Lenovo desktop suddenly died

Q: Lenovo desktop suddenly died

We have a Lenovo ThinkCentre desktop computer, running Windows 7 Professional. It's a few years old, and for the most part has been running fine. However, it has now inexplicably died and won't come on again.

We've been having a few blackouts and brownouts lately. It's not one of those computers that stays off when the power returns; if it was set to 'on' when the power went out, it'll start back up once the power returns.

A couple of days ago, it had gone into standby or sleep mode, and for some reason wouldn't come out of it. The laser mouse wasn't lit up, which often happens when a computer is in standby mode, but when I hit keys on the keyboard, it still didn't come on. After opening and closing the disc drive, and pushing the power button a couple of times, I finally gave up and held the button until it force shut-down. The next time it was turned on, however, it worked fine, and didn't seem to exhibit any unusual behavior.

So yesterday, the computer was working. It was left running overnight, as it generally is. The following morning, however, it was no longer on. Pushing the power button yields no power lights or sound of anything running. I unplugged it from the surge protector, then plugged it back in again, choosing a different plug on the surge protector. Still nothing. It shouldn't be an issue with the surge protector itself, as the monitor and internet router connected to it work. I don't think there was an outage, either, because no clocks were reset.
Does anyone have a theory on why it might have randomly died in the middle in the night, and whether by some miracle, it's something easily fixed?

Preferred Solution: Lenovo desktop suddenly died

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

The Power Supply Unit may have failed. This is a relatively easy fix if you get the part. Any PSU over 550Watts will do. If that doesn't fix it, you can always return the part.
If you need help knowing how to replace the PSU, there are videos showing you how on YouTube

Hello. I have a problem with my Lenovo Thinkpad P51. During my daily usage of this laptop it hanged up for a moment, so I had to turn it off by pressing the power button. For a second on a laptop screen appeared a message "critical low battery error" or something like that. From this time I can't turn it on and when the power supply is plugged LED which should inform that laptop is during charging, is off.I have been trying to put in and put off battery multiple times and nothing happened. Do you know what can be a solution to this problem?

Hey All.....am new at this so please advise if more info is needed or am doing this wrong.

My problem.....
Bought a new computer 2 months and had nothing but problems with the USB ports. Mother board has been replaced twice, now third one is gone.....only the USB ports.
Thank goodness it was under warranty but they are hesitating on the last one.
The computer came with a wireless keyboard, I had and use a wireless mouse, I have a HP printer connected as well as a Maxtor 100 gig external hard drive (which is seldom turned on) The mouse and maxtor were connected to the old computer and worked great, the only things new are the computer/wireless keyboard and printer.

Initially they thougt it was the Ipod which my daughter had, but that was not used this last time, so now they think it is the printer (which was used but not that much). So, now they don't know what causes the USB port to die (all of them). Also, when they go so does the tuner for Meida Center as well as the Card Read.
CD continues to work and everything else i.e. plug in mouse and keyboard.

So...any suggestions as to what casues USB ports to die.....suddenly with no warning, and all at once.

Thanks for suggestions.

Hello.I was using my t420 just fine, no symptomps or malfunctions, till today.I powered on the laptop and after the light and the caps lock led flashed, the wifi icon went on and nothing else happened. The screen reamained off (not just black, really off with no backlight). I've removed the two dimms (one first, then the other), i removed every drive and pci device, deattached the system battery for a minute, replaced the thermal thing between the cpu and the thing that cools the cpu (sorry I'm not english) and yet nothing. Then, when I've reassembled it entirely, it goes on, giving me the message "machine type and serial number are invalid", then goes normally to the desktop. After I power it off, it is dead again. Sorry for the long post.Can you help me? Is there something I can do, besides throwing it in the trashcan?

I was playing a game online at a friends house, using their wireless, when all of a sudden my wireless died. I thought it was just their wireless but when i went home to connect on mine, i still had a problem.

I've tried turning the switch on and off to no prevail. When i go to connect to a network, my wireless detects nothing. I found an option to find the problem, and it told me my wireless was turned off, so i checked the switch and it was on. i also went to my computer and to device manager, and checked my network devices and they are apparently all working fine, so i really don't know what the problem is here.

A:Wireless died suddenly, help

Quite the mystery!!!

If your card was disabled or not working it wouldn't show up with this much information in the ipconfig /all report.

It also looks like you're on Windows Vista of some sorts since your home path is: C:\Users

Your Wireless card's network stack is also working. It's assigning itself an Automatic Private IP Address. (APIPA) That's the weird little address that you get starting with 169.xxx.xxx.xxx in the IPv4 Address line. Usually to me, it means that you computer tried to ask the network for an address but nothing was configured to respond to it. So it gave itself an address - which is mostly useless in this case.

I think, maybe, could you try to disable any firewall settings? (Just turn your firewall(s) to Off and test again to see if the problem went away.) If it goes away, then you know that some rule in the firewall is doing this to you. Do you have Symantec Anti-virus installed? Because I've seen that come with a firewall that screws up a computer on more than one occasion. It wouldn't be the right way to configure a firewall, but it might be blocking the broadcast responses.

I was just browsing the web and transferring some photos from my camera when my computer suddenly turned off in an instant, and now it won't turn back on.

I have had to replace my PSU twice already so I suspect that that may be the problem, but how can I be sure? And what can I do to stop it happening again?

was carrying my lenovo flex 4 in a laptop backpack from point a to point b in a sleep/hibernation state. Upon removing it to use again, the power wouldn't come on as well as the power button led wouldn't/won't lit up.

Did a hard reset, removing battery, pressing power button for 1 min etc, still dead.
I thought it might be the adapter which looked burnt by the two prongs, hence ordered a new oem adapter, still to no avail.

Geeksquad apparently charges a good $50 just for a diagnostic, hence I'd like to know if it's the motherboard or other component based on the symptoms and circumstances.

How can a motherboard die simply from carrying a laptop without dropping it or bumping into anything, which i didn't.

Otherwise, what would be a good diagnostics, that's cheap, including diy?

Hi everybody,I have a Lenovo yoga 2 11'. Windows 10 1511. About one month ago I shutted it down, I don't remember if it was charged or not. I turned it on some days ago and seems that the battery died. What can we do?EM is installed and says that everything is fine. The computer works fine if plugged, but if I unplug it doesn't. Windows and EM say that "battery is charging at 0%". The LED is orange and blinks.If you need other details feel free to ask.EDIT: Latest BIOS installed, Windows is updated, there is no "USB Always on" option in the BIOS.?

Earlier this evening Windows started throwing the "Unrecognized USB device" error in the system tray. Clicked into it and disabled the device, found nothing deactivated, and went about my business.

The system kept throwing the error over the course of the next half hour or so, even after a reboot, and then my USB keyboard and mouse both cut out simultaneously.

So, things I know for certain:

(1) My USB ports are not blown entirely. Speakers still work. External is getting power when I connect it, but not autoplaying or showing in My Computer (external works fine on Ubuntu box).

(2) It is not an issue with just this particular mouse and keyboard. I've tried three of each peripheral (all USB); nothing works. On a reboot, the keyboards' Lock keys give a brief flash, but don't allow any input whatsoever.

Any ideas? I haven't yet tested with a PS/2 mouse or keyboard, as I can't find one, but if I can pick some up I'll give those a run as well.
update: PS/2 hardware does work.

This is on XP SP2.

A:Keyboard / mouse suddenly died

Either your USB circuitry is faulty or, more likely, the USB software has corrupted. Go into device manager and uninstall everything listed under the USB section. Shutdown and reboot to allow Windows to find the hardware and reinstall the software (will require no intervention from you). Once done, test.

A day ago, I was having trouble with my apartment modem, and due to a busy schedule, was only able to do a quick "Unplug and reset" which seemed to work at first, but eventually it stopped working all together. Today, I traveled from my apartment to my "home" home, where the wireless network is set at a "Home" security level. However, my wireless now will not connect at all.

It continues to cycle through "Identifying" yet cannot make the connection. It works through a LAN connection however.

So far, I've attempted the follow:
- run>ipconfig/all, ipconfig/reset, etc
- winsock reset
- system restore

I've searched all over, and haven't been able to find anything helpful. My computer is a Samsung RC512, running windows 7. Here's the paste from my ipconfig/all:

I'v been having some problems with BSOD's lately (BCCode 116) and had been told to do a stresstest of my GPU(GTX 760) with Furmark, which caused BSOD immediately. I then tried swapping out my GPU with my brothers GPU(GT 730), and the test ran for 10-ish seconds, then my computer shut down, and now it wont start up again.

I tried removing the GPU to see if that would help, but no. When I press the powerbutton nothing happens at all. I had a similar problem before, that my PC wouldn't boot, but back then when i pressed the powerbutton the fan on the PSU would move ever so slightly. Now nothing happens.

I dont know what to do now. Any help?

I've searched a bit on the internett and found that people say to disconncet all periferals, and try to boot with just mobo, psu and CPU. That didnt work. I decided to try with my brothers PSU. When I press the powerbutton, the LED at the front of the case lights up briefly, the fans rotate 1/4 of a full spin, and the it shuts down.

Does this indicate that both PSU and the mobo is defect?

My pc suddenly died while I was using it. At the time I was doing nothing more than surfing the net with one browser open. I heard a pop (like a balloon popping) and the pc slowly died like the current was being drained. There was no power outage at the time, plus it was connected to a surge protector. All other things connected to the power bar are still working fine. There was no smoke or burnt smell. When I opened the case I could hear something loose in the power supply so I figured that was the prob & replaced it with a brand new one. The pc is still dead. Nothing happens when I try to turn it on. I have tried removing all of the components one by one & still no luck. The only sign of life is the little green light next to the PCI slots on the mobo. I have not tried to remove the processor as of yet... Is the problem the motherboard or the processor? How can I tell? (I don't have another pc to test with.) Any help would be greatly appreciated, thanks.

A:PC suddenly died, motherboard or cpu problem?

When your PSU fried it may have taken the motherboard and anything attached to it with it. If you don't have a new core two duo or a new socket AM2 processor now is the perfect time to consider an upgrade if you have the money. Rebuilding old technology is often wasted money; it just depends how old you're talking about.

Replace your motherboard and attach just the devices you'll need to boot your computer. You'll need your PSU , processor, video card, hard drive, memory and CD ROM. You'll probably have to reinstall Windows too.

During playing Diablo3 my PC all of a sudden shut down. No bieps, no messages, nothing, just black ... shutdown. Because it was this sudden my first reaction was a power outage in the house. As I was about to check the basement I noticed my screen still was powered on, so it couldn't be an outage.

I tried to turn the PC back on, but pressing the power button didn't do anything.

I did notice the top of the case was pretty warm (not auch warm) but still pretty warm. It's always been like this ever since I bought the PC.

I opened the side of the case and didn't really notice any burning smells or anything, but again, the inside of the case was pretty warm.

Now after a couple of hours the PC still won't power on, so something is probably broke.

I'm a complete hardware noob, so how do I go about checking what is broken?
Is it the PSU? Or the motherboard?

When the PSU is 'on' I can see a green LED light on the motherboard. Is this possible when there is something wrong with the PSU, that the motherboard still gets power?

I'm willing to make the bet and buy a new PSU (because the current one is an unnamed PSU that was included with the low budget case).

Is there anything I can do to check components as a newb?

A:PC suddenly died on me, won't power on anymore

It sounds like your computer has overheated which is why the computer all of a sudden shut down. Try checking to make sure you've got some grey thermo stuff on the CPU.

Last Monday I turned my PC on and after 45 minutes it slowly crashed to a complete freeze up, so I manually retsarted, and it happened again 45 minutes later. Since then, whenever I turn it on, it powers up but does absolutely nothing. There's no beep, nothing appears on screen but it stays powered up. So I thought it's probably the graphics card, so I bought a new one only to find it's not that. The PSU is fairly new, so I don't think it's that. I don't *thinik* it's a hard drive problem because I tested another hard drive in the machine and the same thing happened.

I'm guessing something's burnt out, and I'm worried it's probably the motherboard or something.

I've got a problem that I hope some of you can help shed some light on.

On tuesday afternoon I was working heavily to create a basic linux shell in c, using Bloodshed Dev-C++ and an putty (SSH) connection to the linux servers on my university.

The OS is XP home german version.
The connection was using the built-in wireless connection to a D-Link wifi router. It had a fully charged battery, but was using the the power adapter.

Now, everything was working just fine, I leave the computer for a little while and when I return, it's turned off.
When I try to turn it on, nothing happens. I pull the plug, reseat the battery and nothing happens. When I reconnect the power line, I get a very brief light on the power led, but that is that.

One or two days earlier I had a problem waking up from the sleep state, where the computer stopped loading XP and gave me a black screen instead of the login screen. After a hard off (4 sec power button) it worked like it should.

Does anyone have any idea on what the problem could be?
I called a shop that sells rebranded MSI notebooks, and this was the first time they'd heard of such a problem.

I'd call MSI, but they don't have a support office in Norway. I will use the warranty, but since I bought the computer abroad, it takes some planning, and thus if there is an easy fix I can do myself, I'd rather do that.

Any help you can give is appreciated!

I got my computer back from a friend but i noticed the case fans weren't working. I sent him a txt and he said it was working fine when he had it and my brother said it suddenly stopped working when he was on it so i'm guessing it didn't die due to my friend cleaning it for me.

Only the CPU and GPU fans are running. I have a fan on the side panel wall, back, top and one in front.
The side panel fan works when i connect it to the motherboard and not the power supply.

The back and top fans dont work at all and they are connected to the motherboard via the 4 pin connector? 4 holes made to a square(hope you can understand this).

oo <- like this.

the front and side fans have both oooo cord or ... (3 pin?)

This PC is custom built but the place i bought it from did it for me so everything is neatly done and i cant rearrange most things without cutting the tags that are holding the wiring.

I dont know where to go from here so I need some help.

Heres a link to some photos imgur: the simple image sharer

Pic 1 shows back and top fans not running.

Pic 2 just shows the side fan

Pic 3 dont know if you can see it properly but usually the side fan cord connects to the cord labelled "1" and that cord is connected with the front fan aswell which then is connected to the power supply.

pic 4 just general pic of my comp.

Hi all,
Lately I've had my laptop plugged in a lot because I've been running some design analysis software thats required a long time to solve. Anyway my laptop suddenly just cut off today whilst on battery. Straight away I assumed it was the battery as I had a similar issue back in 2010 with my old device. I've had my current laptop for about 2 and a half years. I ran a battery report which came up with the following information:
Cycle count: 489Design capacity: 48840Last full charge: 38373
So its obvious my battery isn't at full capacity as expected. However, could this be the cause of it randomly losing power? I'm thinking more of a calibration issue. Any ideas on how to calibrate?

Many thanks in advance!

I run a dual monitor setup with two 19" widescreen LCD's. This morning my primary monitor wasn't turning on. After some messing with the cord I got it to turn on. Later on it did it again, but I couldn't get it back on. I ruled out the cord by using a different one, something happened to the monitor itself. At first I thought the screen went out itself, but I managed to set both monitors up as clones and there's a very faint image on it still. I can see the things I'm doing on it, but just barely.

Hi everyone,

I went to my PC this morning to discover it refused to turn on, and no response of any kind happening (no sounds, lights or fans operating).

My initial thoughts were that the PSU had died... so I went and picked up a new PSU, which didn't change anything. Still no response.

I'm now assuming the motherboard is faulty.


some factors that may or may not have anything to do with the cause of the problem:

- Dust - when I opened up the case there was a lot (almost a blanket) of dust in my zalman CPU fan, graphics card and also a little generally within the case. Although I hadn't experienced any artifacts suggesting stuff was overheating (plus it's damn cold in my house this time of year, so that probably helped)

- There was a powercut during the night - somehow this might have triggered what's caused the fault? I also had set my PC to sleep as per usual, instead of switching it off.

- The extra Front panel USB ports on the top of my case stopped working about 2 days before. I accidently tripped over a USB device plugged into it, and it twisted the port slightly, but still carried on working for the rest of the day, but at some point it stopped and I had to only use the back ports.

Is there any suggestions you guys have to find the cause of the problem?



A:Suddenly died - no power or motherboard response

Hi Mike. The power cut you mention is interesting. Did the fuse in your house trip? Are other items in the room working off the same plugs?..because thats happened to me before.

Hello All

Alienware M17X R4  died suddenly after “passing all diagnostics”
My  M17X R4  does not turn on either with or without A/C adaptor
But attempts to boot with the battery alone. But shuts down after the keyboard light flickers twice

Disconnect all the external peripherals from the computer including the battery and the ac adapter and release the flea power by pressing and holding the power button for about 30 seconds.
 Tried  to turn it on with with the cable plugged in without the battery,  which didn't work
Re-install the battery with the cable unplugged
Turn on the computer and check. Nothing happened except the keyboard light flickered twice without response
Just before the 2nd flicker, you would hear a “click or flicker” as if something is trying to kick in which could not.
What I am saying here is that something is failing before it even gets to POST.
What is it?
It is a shame that a gaming lap top as solid and expensive  as M17X R4  should disappoint and fail just like this.
Experts should tell me what going on.
Could the GPU thermal tape or CPU thermal paste help??

My 2 year old moderately used laptop battery suddenly died after a windows update. Everything was working fine, the battery still held charge for over 2 hours and now it doesn't work at all. When I hover over the battery icon it says '79% available (plugged in, not charging)'. If I pull out the charger my laptop stops as though it doesn't recognise there's a battery. I ran the HP battery test and it told me the battery is dead. How can a normally functioning laptop battery suddenly die after a standard update? I see there are a number of customers complaining about the battery not charging when switched on but my battery doesn't work at all - although it apparently is 79% charged. Is this normal for HP laptops?

I've been using this laptop for a few years now, and while it has its fair share of small problems (track pad not working, keyboard coming loose and sometimes not working, speakers slowly dying, start ups where the screen doesn't turn on.) Despite those issues I always found a way to either fix or at least work around the problems until today.I was just watching YouTube videos when the laptop without any warning shut off instantly, even though it was plugged in, and mostly charged. After that none of the power lights would go on at all, not even the charging one. I tried unplugging it, removing the battery, holding down the power button for 30 second, and every combination of those steps I could think of. Is there any hope of saving this laptop, or is it bricked?

Hi All, My laptop (E50-70)  is almost 3 years. The battery behaves normally most of time. But sometimes it died suddenly without plugging into mains after 5 minutes used when it was waken up from sleep mode. This happened many times even the battery was fully charged before entering sleep mode. But everytime, when I took out the battery from laptop, and put it back then plugged into mains to charge it. It behaved normally again until unexpected same incident happened again. Do you have similar experience? Any idea what's wrong? Many thanks,Cheers,J

Hey everyone,

My laptop (i'm not sure the make or model matters) suddenly died, it was working fine one minute, left the room for around 30 seconds, came back and has seemingly has no power. The machine has been running purely off the power adapter because there is no battery. There's no lights on, indicating an electrical connection; it's completely dead. I used a phase tester to confirm a good power adapter, so the problem seems to be with the computer. I don't think the electrical input socket (?) is at fault cos it's not loose.

Does anyone have any suggestions? Maybe it has something to do with that internal coin-shaped battery?

I'd really appreciate any help because i'm completely at a loss as to what i should do next...

Hi jgraves12, Kind of unsual for it to shutoff and not able to turn it on all of a sudden. Does it have no signs of life at all? No lights on any of the indicator. If that's the case there are couple of things you can try.? Remove AC adapter, press and hold power button for 30 secs, replug AC adapter, turn it on using Power Button/Novo Button (Button beside the power button). If you're able to turn it on using Novo Button, go to Normal Startup.? Test with a different AC adapter, make sure you charged it for more than an hour, or test the AC adapter on a different computer, see if it will charge.   Hope this will be helpful.

16 month old Lenovo B50-30 All-in-One - Type F0AU00CLUS powered off abruptly whilst in use today and refuses to power on. No activity except a light in the power switch. I've tried unplugging, waiting, holding the power button whilst unplugged, holding the power button whilst plugged in. The machine refuses to power on, it won't POST, there is no "beep", there are no fan noises and no hard drive spinning up. Of course it's about 16months old and out of warranty. This computer has been lightly used as a family PC with only an hour per day on it at most. No heavy duty applications, no over heating/over-clocking. Completely disappointed that it would die like this. I've built PCs from parts before so if there are any diagnostics or known issues with easy fixes I'd be fine to try those out.  What are my options and what kind of support should I expect from Lenovo?

Here's what happened. We use Avaist. The other day, a window came up and said that Avaist was expired and we needed to enter a new registration code, but Avaist was last installed in Nov., and should have expired yet. Well, sometime between it expired and we reinstalled it, something must have gotten in, because when we rebooted, the boot scan came up and just about every file that it scanned was put in the chest and then it said the chest was full, so we escaped out and rebooted. Now it loads up to the user name/password login box, you hit ok, and it says loading personal settings, and then immediately logs back off to the login box. Does the same thing when trying to load in safe mode and from last good known configuration.

Please help.

4 year old laptop wasn't charging properly, it was being very fussy about the exact position of the power cable in the socket. It has what looks like a pretty common power connector for lenovo, which is a USB sized hole with a single centre pin. I looked into the laptop socket and saw that as well as the conductor for the centre pin and the outer sides, there was also 4 little tines on each side between the centre and the edge which were clearly all bent off in wrong directions (looked like an old toothbrush inside) I'm guessing the centre pin is +ve, the tines are -ve and the outer connections are just mechanical/shielding. I straightened these all out with a pencil but I think I must have momentarily shorted something as now the laptop shows absolutely no signs of life when I hit the power button. Tried various tricks I've read online about various sequencies of hitting the power button with the battery in and out but no luck. The laptop was fully charged before I started this, but I didn't disconnect the battery before starting which I probably should have. So I'm guessing I've shorted the power rails on that connector. What damage have I likely done? I'm amazed that there can be a design where very flimsy pins inside an external connector which are clearly easily bent can cause such damage if they touch another pin 2mm away from them. Is there any way to save this laptop? If it's a case of replacing an SMD fuse soldered onto the motherboard I can do th... Read more

I made the mistake of using my laptop without the charger and letting the battery run down. I launched The Sims 4 before getting up and grabbing my charger. I didn?t check to see if the laptop was actually charging after I plugged it in, simply because I?ve never had an issue before. So I set my laptop down and walked away, letting my game load. I left the computer alone for nearly 20 minutes. I came back and as soon as I went to use it, the screen went black. Luckily though it wasn?t entirely dead. I pressed the power button and it came back on briefly. The battery symbol had an ?X? and it said 0%. I noticed then that my charger wasn?t completely plugged into the machine. So I plugged it in properly and  I didn?t see a little charging symbol or anything but it didn?t shut down immediately - The Sims was still running in the back ground. I loaded up a world and after a minute or two it died. I tried to turn it back on but I wouldn?t turn on. So I let it sit unbothered, charging for several minutes. I tried to turn it back on and nothing happened. The power button wouldn?t even light up. However, when I do press it, there?s a little red light that blinks at the bottom of my laptop. I went online and tried to find some solutions. I tried the one where you detach the battery and the charger and hold the power button down for 30-60 secs and that produced no results. I think it might be a charger issue, but how do I know for sure? Any...

I bought my Lenovo Yoga 2 Pro in end of March2014.Yes, 2014.I used it happily for about 3 months and then suddenly I got the blue screen and then it never turn on again ... NEVER EVERI bought it in USA in Knoxville, TN at a best buy, but at that moment I lived in Berlin, Germany. So I tried contactng Lenovo Customer service there and they say becuase i did not buy the extended warranty, they could not do anything I have to solve it with US Customer Service.In February 2015 i travelled again to USA for work, and then I tried solving my problem. Only to find out Best Buy did not recognize my purchase because I did not have the ticket and they could not look me up on the systme... that was a lie... which I beleived... So i returned to Germany with my "brick" ( that's how i call my Lenovo Yoga since then).I live in Argentina for the past 2 years, I took the brick to a couple of services (even Lenovo "official" Services in Buenos Aires) and they both said there is no solution is motherboard problem is completely dead and useless...I am in USA one more time for travel, this time in Atlanta and back in Knoxville. I wouldlike to have a solution for this, whatever works... I do not want to carry the brick with me anymore. I am leaving to Argentina on Monday morning, I tried contacting Lenovo through Support but they did not answer so I am talikg my last shot through here in the forums (I just read some people got their problems fixed in the last month or so).I don't mind what I g...

I have been having issues with my computer since the day one. When I powered up the computer for the first time Polish (Machine was set to have Polish language for somewhat reason) BSOD with message MACHINE CHECK EXCEPTION greeted me. I restarted the computer and everything seemed to be fine. However, an hour later another BSOD with message saying CRITICAL PROCESS DIED was displayed. I updated the bios and re-installed Windows to make sure this is not a software related issue. That did not help. I am still getting BSOD's with MACHINE CHECK EXCEPTION, CRITICAL PROCESS DIED or UNEXPECTED STORE EXCEPTION. The progress counter stays at 0% and I waited for two hours for it to load. I have noticed that one occasion when errors occur are when I plug in my machine for charging. But, it can also throw an error with nothing specific going on. I ran Lenovo diagnostics tool(Check the attachment) everything seems to be fine. I contacted the seller (they claim to be Lenovo Platinum PC Parter) and they offered to send the laptop for diagnostics. They were not able to find the issue and as a consequence of that I had to pay for the shipping and diagnostics and the problem still remains. I contacted the seller one more time and they offered me to send the laptop for diagnostics again. I asked them to replace the unit, but they refuse to do it because computer "works fine". At the end of the day I have a computer that I cannot use and I have no idea how to solve this problem. It is m... Read more

A:Lenovo Yoga 720 Critical Process Died

Welcome to the forum.
Sorry to hear about this experience. This should not happen with a new system.
From what you have described this system did not work out of the box. It is not your job to debug new PCs. It seems to me that you should contact Lenovo in Lithuania, explain your experience with this Platinum PC Parter and request a new system.

We have lenovo V580c notebook which HDD has died - it was already refubrished 2 times lol and it has died again. It has Windows 8/8.1 preinstalled and we have upgraded to Windows 10 recently. But since HDD has died, we needed to reinstall the system on the new drive (we have msata ssd for that). Anyway, I tried to boot notebook with DVD with burned clean Windows 10 ISO image but notebook don't want to boot from the DVD all of a sudden. No changes in BIOS could help to solve it - notebook just not recognizing any drive now. It goes through all boot options and stopped at network boot which we don't have. And then we see just a small windows with booting option which are not working any way. Here are some pictures: http://imgur.com/a/6R185 http://imgur.com/a/112HY http://imgur.com/a/K1k8Q I already tried lall posible BIOS modes, loaded safe settings, used UEFI/Legacy/Both, disabled/Enabled Secure boot. Nothing helps and the notebook is literally unusable now because it is not acepting any storage/disc to boot from. I even tried to remove any booting unit like HDD, DVD and new msata I tested before. Notebook just not even trying to boot. Obviously it is out of warranty now. What can I do to fix it and make it acept to boot from DVD again? I don't want to bring it to the perair service because it wil cost us the money. This product should just work at the first place. We had so bad experience with lenovo with this notebook that I won't buy any other their product anymore.

I have a Lenovo Thinkcenter i7 M92 that worked a while ago and when I turned around to work on another computer, it apparently turned off and now the power will not come back on. The power button wont even light up, nor will the lights where the network cable plugs in. Have tried different outlets, different power cords. I am thinking it is a power supply issue but I cannot find a power supply to order. Any suggestions would be greatly appreciated.

Hi all,

Recently purchased a Y700 15isk
(i7 6700HQ (2.60 GHz) 8 GB Memory 1 TB HDD NVIDIA GeForce GTX 960M 4 GB GDDR)

The machine came with windows 10 and I partitioned the system and installed fresh copy of windows 7 and windows 10 (dual boot).

So over the weekend I decided to build overviews (via software) of my music collection. Since the laptop has 8 cores, it was building 8 at a time. So I imagine that the system was working full throttle. About 2 hours into the project, the laptop completely went out. Suspecting a heat issue, I checked the brick, it was hot but still was giving me a power reading via my ohm meter.

Plugged the brick back into the laptop and the lights on the front of the system did not turn on. Anyways pulled the battery from the laptop and did a discharge cycle and nothing.

I suspect my motherboard or cpu went toast! Seeing that I will be using this new laptop to dj professionally, obviously I am glad this happened at home.

Anyone have any thoughts on this? I can't believe that a new gaming laptop would fry while working all 8 cores. Fans also seemed to working while this was happening. In the power settings I also remember setting it "performance".

What are people using to stress test laptops? I will be sending this one in for repair and then stress test the one I get back.

A:New Lenovo Laptop Died While Rendering Files (All 8 Cores Being Used)

Laptops never has a good cooling system and always run hot.
The CPU has a temperature trigger that will shut down the computer to self protect.
As it also has a battery, I would say that is probably the internal power supply. When plug ed in, does the charging led goes on?

No reason to work on performance profile settings.
You can run on balance profile settings and adjust the minimum and maximum CPU clock. I suggest 20 & 100%. The clock then will automatically be set as necessary.

The i7 6700HQ has 4 cores and Hyper-Threading makes two tasks share one core, simulating 8 cores.

Hyper-Threading is only effective with high multitask programs, like Photoshop, Autocad, games etc, that split a complex task into multiple tasks.

Just got this laptop 2 months ago via amazon. I am a DJ and use Serato DJ software. I have only played 1 party with the new laptop. I am running windows 7 and windows 10 (difference partitions) Today I decided to build the overviews of my music collection. The software uses all 8 cores (8 songs at a time) to build them. I had the laptop running for about 2 hours. Everything was running fine. I even have the laptop slightly elavated in the back to get extra air flow. All of sudden the laptop shut off. I noticed that the charge light on the front of the laptop was no longer while. Power brick was pretty hot which seems normal for the intense core usage. Called tech support and went through some tech support, have to call back since there database was down. I suspect something on the laptop motherboard or memory etc went toast. This is my first Lenovo laptop ever. I have been a Dell guy for over 10 years, never ever had any hardware issues in 4 other laptops.  What can I expect from Lenovo warranty service? Anyone have any other thoughts on what the heck could have happened. This is probably the most intense I have run the laptop. DJ with the software isn't as intense as building overviews. Think of it as rendering.

I'm posting on my laptop... desktop (WIN XP) just died... Was just watching a divx file... then all of a sudden, complete freeze. No response with ctrl-alt-delete, no mouse movement, no keyboard keys work. I had to hit the reset button on the tower. But nothing... no POST beeps at all and the video is blank.

I've got 3 HDDs and so I left my primary master plugged in and unplugged all others. The harddrive (Maxtor) doesn't seem to make the power up sound. I plug my slave drive (Western Digital) as master and it makes the power up sound, but still no POST beeps. I try the 3rd drive, also a Maxtor and don't hear a power up sound (maybe that's normal)... no beeps.

I try every combination of the 2 RAM, leaving 1 RAM, leaving no RAM... nothing changes, no POST beeps.

Any leads ? What usually could cause a complete freeze like that ? Video card ? HDD crash ? RAM problem somehow ?

Im in need of some advice, my computer died today when i went to shut it down instead of going through the normal process of windows shutdown it just instantly turned off, and one of the lights on the front strated flashing i have to lights onthe front one is the hard drive and tbh im not sure what the other light indicates its just on all the time pretty much when my pc is on.

anyways iv tried changing he power cables and letting my pc cool down but no luck its still dead as a dodo. im thinking its not the power supply unit as the ligh on my network cable slot is still lit up so it must be getting power right, perhaps its the switch? i dont know im really worried incase its a problem with my hard drive and i might have lost all my uni work on there!? but i really dont know hope someone on here can give me some advice, i just went to a local pc repair shop and the guy didnt want help me at all because he said he didnt have enough time to fix it anyways any advice would be great

thanks alot

A:Desktop just died, wont switch back on please help

When you attempt to boot up your pc what happens? do you have anything displayed on the screen, do you hear the computer being turned on at all or is it just not starting up at all?

Indeed my guess would be a Bugged PSU if nothing pops up on screen and you don't hear the pc turn on. If you hear the pc turn on (fans spinning and all) but do not get anything on screen followed by a shutdown then its most likely the motherboard.

You might be running a cheap PSU and that has a potential to even fry your computers parts and components. If it boils down to the PSU, i suggest investing in a reliable PSU like Antec perhaps or Silverstone

Installed a wireless network at my sisters house about a year ago. HP desktop pc (win7), Dlink router, Comcast Internet cable modem, and (1) toshiba Satellite notebook pc (win7). About a week ago, the mobo on the hp fried, and my sister doesn't want to replace it. She wants to keep the notebook only. I can install the ethernet cable directly into the toshiba, or (I believe) continue using it wirelessly without the desktop, but either way, should I re-install the software that came from Dlink directly onto the notebook? I believe the answer is yes, but would like some advice. Thanks.

A:Desktop died, need to re-install router software?

I have never installed software that comes with a router, when used with a cable modem. You should be able to configure the router settings using the routers web interface.
