Lenovo G50-80 died after trying to fix DC power jack

Q: Lenovo G50-80 died after trying to fix DC power jack

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 that sort of thing easily enough as I'm into hobby electronics.Is it likely that it's the battery circuitry that's broken rather than the laptop?

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.

I need information about wiring of the power jack in Lenovo Y50. I mean wiring at the plug which is plugged into the motherboard from the power jack. Please refer to the attached photo. There are 5 wires (counting from left): 1 - blue, 2 - black, 3 - black, 4 - red, 5 - red. I need the following information:1. What is the function of each wire (ground, power supply etc.) and required voltage on each wire once AC adapter is on?2. Are 2 black wires (wires 2 and 3) internally connected? I checked with multimeter and among all pairs of all 5 wires, only those 2 wires are shorted? Is it correct?

Earlier this week I stood up while holding my Y540.  The power brick, which is quite heavy, fell off the desk and ripped the power cord out of the DC-IN power jack.  The plastic clips that hold the power cord in place were destroyed, and now I can't get a stable power connection anymore. I'd like to replace the DC-IN power jack on the motherboard.  The problem is I can't seem to find the part anywhere.  Lenovo won't sell it to me (it's an FRU only part) and I can't find anywhere online that sells an 81Q4 power jack. Does anyone know if there are other compatible DC power jacks I could use for my Y540?  I'm quite comfortable replacing parts on a system board, I only need to find the appropriate part.   Thanks for any help you can provide.

Hi!I accidentally broke my notebook's power jack (2 of 5 wires broke off from their pins). The number of the part I need is DC30100KQ00, but at the moment I hardly find any (ebay's shipping can take up to 2 months, and I don't have that much time).My question is what are the differences between these parts? I mean I've seen many of these with the same looking connectors I need, but they're related to other models. Otherwise, can I cause any trouble if I try to replace it with a part from a different model (e.g. G500)? Thanks,Mozes

Hi!I recently got my hands on my friend's old laptop that hadn't been used for a year. The problem with the G510 was the power jack. It was pushed back and repaired multiple times by professionals but still didn't completely work.I thought that if i bring the power jack outside the laptop it would work. But it doesn't. I plug in the charger and nothing, no led lights no fan no sound. The same charger worked on another computer.So i removed the power jack and i saw no external problem with it. I don't have a multimeter. Next i thought the power jack doesnt really cost much, but then again, the shipping costs would be overwhelming and i can't afford it at the moment.I also tried turning it on with only one memory card, done the 30second thing, charging without battery in case the problem was there but still nothing. The silence is killing me.Could there be any way to charge the battery outside the laptop? Or do you have any other ideas i could try?

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A
 

A:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!

Hello!

My Toshiba Satellite P755-S5265 has not been able to turn on at all. That's because the AC adapter would not be charging the battery nor would it operate the computer.

Whenever I would plug in my adapter, a weird clicking noise would come out from the computer. Also, the AC adapter charging light would blink continuously as well. I

took apart my laptop and discovered that the end my of DC power jack was the source of the clicking. When I mean the end, I don't mean the area where I plug in my adapter, it's the other end that's connected to the motherboard.

Does anybody have any advice on what I should do? Is my laptop dead and done for?

Thank you so much in advance!

When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

When I remove the battery and plug in the charger to the new DC jack, no LED. Hitting the power button results in a flash from the power button light and power LED for an instant but no POST or boot.

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.

Hi. Im new on this forum, but I have a problem with my Inspiron 1545 laptop from Dell pre-loaded Windows 7 Home Premium 64-bit (although I did re-install several times with OEM OS restore disc). Money is tight for us now, so my AC power jack on the side of my laptop (or the end which connects to the jack) is damaged. I don't know what it is or how serious it is. Once for a while we had to protect the cord from slipping out using duct tape. The only thing I really know is that the coded white rim on that end of the cord, a very small part of it is chipped. And my battery needs replaced, do I need to still fork over an expensive sum for a brand new one?

Granted those aftermarket replacements are not necessarily in the same quality as the original parts.
You often trade off quality for price.

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?

Hi all,

my power supply died two days ago. By chance, everything else seems in
order, except for the USB ports which act strangely.

I bought a new power supply and installed it. The computer boots normally
and the OS starts without a problem when there is no USB devices plugged to
the motherboard.

If I try to plug something to the USB ports while the computer is on, there
is no problem and all my USB devices work fine.

But if I boot with the USB devices plugged to the motherboard, the computer
doesn't even try to boot (nothing happens when I press the power button).

Someone have a hint?

If the USB ports are not working properly, should I change the motherboard (in case it blows up something else with time) or just disable USB ports and buy a PCI USB card?

Thanks!

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.... Read more

My daughter's Dell 1737 refuses to turn on. For the past few days, the computer would turn off without warning but she was able to restart it without issue. At one point, she notice a burning smell. Today it died completely. Pressing the on button has no effect. She cannot recall if she heard the fan running or not or if the computer feels hot.

Other background;

Removing the battery and running on AC does not work.

The power switch is new (due to replacing the back cover six months ago).

The ac charger is new (less than 6 months old) and the blue LED on the cord lights up. When plugged in, the white light on the computer comes on and goes off immediately.

The battery is original. Probably wearing out but running on AC is okay for now. When I push the test button on the battery, I get at least 3 leds lighting up.

Inverter, keyboard and LCD power cable have been replaced.

I am not sure where to start. My gut says power supply board. I would think a bad fan would not prevent the system from trying to start. A dead MB is a possibility but wouldn't I see some signs when trying to power up such as flashing leds?

I would like to fix this since she needs for school every day. I do not want to replace it since she is going to college next year and the college might want a certain brand.

Any ideas?

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?

Old Power Supply: http://www.newegg.com/Product/Produ...ords&cm_mmc=KNC-GoogleAdwords-_-pla-_-NA-_-NA

It's a pretty by the book build. Last night though, I walked into my room and noticed the power off, and it wouldn't turn on. I opened it up, checked all the connectors, gave it another shot, and nothing.

My old computer had a 750 watt Cooler Master (http://www.newegg.com/Product/Product.aspx?Item=N82E16817171024) in it, so i took that out and tossed it into the new system while I wait for OCZ To send me a new PSU. Everything seemed great, I did my normal tasks for the rest of the night. When I launched Battlefield 3 though, the PSU actually makes a very odd buzzing noise. I don't remember this at all from my old computer. The red warning light doesn't go on or anything, it just buzzes. It also happens in Dungeon Defenders. The second I turn either game off, it stops.

Right now I'm back to basic tasks, but is this just due to the extra load from the new system? My old computer probably could have run fine off something much weaker than 750w (it had 8800 gt / Q6600), so I'm wondering if this it's just finally getting a workout or something. It has always run fine, I'm not sure why it would act up in the new comp. I'm sort of stuck until OCZ Gives me a replacement. Is it safe to run this thing?

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 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.

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.

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...

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?

cheers

Mike
 

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.

Oooh, dust will kill in the long run if it's not cleaned...

Bit of a long story for this but bear with me.

I was playing a game this past sunday when my main pc lost it's power, after it died I heard what sounded like metal hitting metal within my case, I took my power supply out and took it apart to find what looked like a coil wrapped around a plastic tube, half burned, so I guess it melted itself off. It was my fault as the inside had tons of dust clogging the fans and vents. Luckily I had a backup for just such a problem, I borrowed the power supply within this secondary pc, it has a 1000watt psu(sli ready) whereas my old had a 600w(also sli ready), I figured it would be a more than suitable temporary psu until the replacement I ordered arrived.

However for whatever reason it won't work in my main pc, whenever I boot it up, everything seems fine but after so much time of being in use the pc just loses power. If I do nothing it will stay on, if I do anything other than idling it loses power. If I scan using MSE it always crashes around 7 minutes or so of scanning but spybot can scan completely, if I browse it tends to take a bit longer to crash (around 30 minutes more or less). I have ran a temperature detector in the background as I scanned and did other things and nothing ever went above 50C so I'm fairly certain that it isn't a heat problem.

To be honest I've been pretty lucky with most of my past pc's, I've had this one for about 8 1/2 months and other than a few random crashes this has ... Read more

THat is frequently a result of a power supply burning out. Especially if it was a lower quality manufacturer PSU

I have a 6.5 yr old e9180t which the power supply died on me this weekend. The unit has an interesting history. The mother board was defective when I bought it and they had to finally replace it along with thousands of others. This unit coined the term inherently defective with google at the time. They rolled it our before really vetting it properly. When I looked inside the box when I first got it I noticed how crammed the interior was compared to my previous unit.  This unit has always run HOT. After years of the heat build up I eventually just removed the side panel due to the heat. So when the power supply died this weekend I discovered another big design problem with this unit. For the first time I removed the top plastic panel . . .  this panel completely hid and covered a vent for the power supply the whole time! The vent was completely covered with thick dust. I literally had to peel the dust off this area. I always used air to blow the dust way inside but since there was no vent visible I had no idea about this issue and never saw the need to remove the top plastic cover.  So I plan to replace the power supply and have two questions. 1. First what is a good replacement? I see that EVGA makes these power supplys where both ends of the wires are plug in which seems like a perfect DIY approach. The current dead power supply was a Samsung 460watt HD642jj. I use two 27" hp monitors with this unit and work on graphics mostly during the da... Read more

A:Need to replace an overheated power supply that died for my ...

After posting this I thought about the issue with the power supply and HP must have installed the power supply upside down and that is why this power supplied died and why this unit was always super hot. I just looked at the power supply and yep I think it was upside down. For years I have been plugging this in on the upper right hand side not the left hand side. The only person who has worked on this computer was the guy who was hired by HP to replace the motherboard after two months since the board was defective from the get go. I wonder if he had taken it out and put it back in wrong? I don't know since I thought HP and the guy knew what they were doing and I had no idea to keep a close eye on how the power supply should be. Unbelievable!

Hi. This is the story. In the middle of my son using the computer, it just shut down. I came down to the room where it was a minute later, tried flipping the master switch on the surge protector off and on, then pressed to power button on the case. It started up. A few minutes later my son called me again because it had shut down again. The former trick didn't work. Here's what I've tried:

Flipping the I/O switch on the power supply both ways and trying to power up.
Unplugging the power supply from the surge protector and plugging it with another cord directly into the wall outlet. Then flipping that I/O switch again.

Nothing happened. Does this sound like it's the power supply?
 

A:Computer died!! Is this a power supply problem?

I`m afraid it does sound like the psu has gone bad.

However, the only way to tell for sure, is to try another psu, and hope that`s all it is.

Regards Howard

2 days ago the power outlet that my computer was placed into was kinda half exploding. And the "lightning protector" that was attached into it died. I was trying to connect the computer to a different power outlet , and the computer won't turn on.
Not sure what happend... So Idk what to do... Should I buy a new power supply and see if everything is ok? Or just give the computer to some lab and have em to "make it work" ??
 

A:computer died / power supply replacement

Anyone? No sense? It's not like a genius question. Just kind of a "your opinion"

ok so my pc bas been running fine since i built it- no errors. Then to day i was playing an online game when the power kicked out then back on. My comp is on a surge protector so i figured no big deal. I turn it on it starts to boot, then I get this

For Realtek RTL8111B/8168B Gigabit Ethernet Controller.
Pxe-E61: Media Test Failure, check cable
PXE-MOF: Exiting

I've tried switching the boot up order and all and it doesnt tell me anything different. Some I think said they could still log onto their pc but i cannot- any suggestions?
the reason I posted this again because I did find a few threads on this, but mine seems to be different in the fact my pc was working and already built.

I have 3 computers; the one I'm on now which is plugged into a surge protector, one in an office that is just for checking email and such, and a system behind the TV running linux and MythTV for PVR functions. Besides the one I'm on now the other two are just plugged into the wall, due to the fact that I'm lazy and didn't buy more surge protectors. Please do not patronize me about not hooking them up to surge protectors...I really don't care right now.

After last night both computers that are not on surge protectors exhibit the same exact problem (which to me is very strange). The power button has no effect, they will start if you plug the cord into the power supply and its switched to ON. Obviously it won't start up if the power supply is switched off. So as soon as you plug in the cord they turn on, all the lights on the front panel (power, HD activity, etc) remain on but the monitor will not turn on and it won't make the "everything is cool" beep sound.

Both computers exhibit that EXACT same problem which allows me to rule out various things such as individual component failure (though I suppose it is possible yet highly improbable).

Are these symptoms of a computer damaged by a power surge or something else? Solutions?

*note: I know my way around computers (I built all three machines from parts) and have checked all the usual things (connections, etc.). Yes, I'm an ***** for not plugging them all into surge pro... Read more

Try a working PSU in those dead bodies. If you're lucky, the fuse inside the unprotected PSUs may have blown. Worst case, you can play Scrapheap Challenge.

So i had my pc tech stick my mini ITX board into a new case and all is working good, but i notes he turned off a setting in the bios he told bios to not halt on errors, i went and turned it on and i see the reason he did is due to the power sensor not being there anymore, as it had a power board in it that distributed power to the system, and i can see on the mini itx board were it would have been. so i called him up and he said it wont hurt anything he set it like that so it would not be annoying to me, that the board is fine and working correct it just had a sensor that is not there anymore. so should i leave the halt on all errors off, or turn it back on and just hit the F1 key to bypass it. does it hurt anything to have it off he says it does not, and mine was a special case as there was nothing we could do about it. as the sensor was on the dead power board and dell wanted way to much money for it so i just gutted the x51 and the machine has been working great, and runs even better.

A:so i gutted my alienware x51 as the power board died had ?

I always use "Halt on all errors" because I want to know in advance of OS loading if something is amiss, but it really has nothing to do with reliability and speed of going thru POST or loading OS and it's further operation. If everything is working right it all comes down to personal preference.

Hi all,

Recently purchased a Y700 15isk
Specs:
(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.
