Lenovo y50-70 won’t turn on, fans spin when plugged in while laptop stays off.

Q: Lenovo y50-70 won’t turn on, fans spin when plugged in while laptop stays off.

Hi there,i just unpacked my laptop from a flight and now it suddenly doesn?t turn on anymore.when I press the power button nothing happens, no indicator leds, nothing. When I release the button I hear that thud noise you hear when you manually kill a laptop by keeping the button down. Now the weirdest thing: when I plug in the adaptor the fans start spinning like crazy, immediately when I plug it in, I don?t even need to push the power button.the same thing happens when the laptop is unplugged and I keep the power/reset button down for a longer time, the fans start spinning out of control but no leds, no nothing, and they immediately stop when I let go.If anyone has any clue how this could be or what to do please tell me. I will contact the seller on Monday (I have had this laptop for 2.5 years, thank god the insurance runs for three years) but as I?ve just moved to another country I?m not sure if that?s going to work out.Any help or suggestions appreciated.

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.)

Hiya,
Here's what has been happening:
PC won't POST. I can't get to Windows or even the BIOS.
This has been an ongoing, intermittent (on/off) problem which seems to have now become permanent.
There are no beeps when powering on.
I replaced the PSU with a new CoolerMaster one in an effort to resolve the issue. No luck.
I've unplugged almost everything from the motherboard and tried powering on, which includes:
HDD
RAM (2 sticks: 4GB, 2GB)
CD/DVD ROM
Peripherals (including, embarrassingly, the Power button...)
Mobo fan (which is the one that wavers every few minutes)
The only items I did not unplug/disable are the CPU fan and any onboard ones, e.g. integrated graphics.

Some history now:
The PC has been having this problem for some time now, i.e. months. Eventually, it would POST and then go to Windows until Friday. Now, it just sits trying to POST. The motherboard fan will waver from slow to fast every few minutes. (I timed it and the wavering has no exact pattern.)

Side observation:
When removing the 4 gigs of RAM, leaving only the 2 gigs, PC freaked out and turned on and off several times before finally POSTing and going to Windows normally.

Today, I removed the CMOS battery for quite some time, maybe an hour or more. The PC was unplugged when removing it and after so I hit the power button. After popping the battery back in and turning back on, I still get nothing.

Can I turn the PC on with the CMOS battery removed? Do you think it would help ... Read more

Good day!

My cousin asked me to troubleshoot the problem of his desktop. He was telling me that it is not turning on. I was caught by surprise when i turned on the PC when suddenly I heard some kind of explosion. It sounds like a blown capacitor or something to that effect. I immediately unplug the power cord from the wall outlet. I checked all the capacitors and looking for any damage and fortunately it's all ok. I smell the PSU to check if there's any short circuit occured and there was no foul odor or something. I removed the PSU from the casing for and opened it for inspection. I found out that the fuse exploded and broke into 2 pieces. I don't bother to repair it but instead I bought a new 700 watts PSU.

After replacing the PSU I turned on the PC but i found out that the CPU fan will spin for half a second and turn off. Led green light is on but no post or beep sound. I did some troubleshooting and these are as follows:

1. I removed the motherboard from the casing and put it on top of the table with cardboard underneath.
2. Clean the RAM stick and tried on other slot.
3. Clean CPU heatsink and fan since it was clogged by dirt and replace thermal paste.
4. Replaced the CMOS battery and move jumper pin 1-2 to 2-3 for about 2 minutes.
5. I turn on the PC without the video card, hardisk and keyboard.

Motherboard: asus h81m-c
CPU: Intel core I7

A few months ago i built a system through a popular computer company, ibuypower, and was initially pleased with the performance of my PC. I was then forced to take a few months away from the system due to work, during which it was stored in a safe dry location. Upon returning the system had the issue stated in the title. I have replaced the power supply with a far better one (went from 450w to a 700w) and the same issue peristed with the new power supply, which works with the tester it was shipped with. I've read about it possibly being the Ram, so i have ordered a 16gb ddr3 ram upgrade (2x - 8gb sticks) and they should be here within a week. I also read that it may be the CMOS battery but those are unable to be shipped through the mail so im having trouble tracking those down here in Japan. If somone could help me figure this out i would greatly appreciate it. I've cleaned and tested everything i can and i can't find an issue other than it physically wont function. Also, in case anyone was wondering this thread was written from my laptop, not the PC.

Much Apreciated

I see others have had this problem, but the classic ?hold the power button for 10 seconds? trick isn?t working. This has happened numerous times in the past and typically it just eventually turns back on, seemingly with no rhyme or reason behind it. This time, it has been well over an hour. It?s turned on twice, gotten to the lock screen, then turned off again & I cannot get it back on.  It is certainly not an issue of wear and tear-I use it minimally, however when I do use it, I really need it to actually work.  What is going on and how can I fix it??

Hello everybody,
I have the following problem:
I have an Alienware 17 laptop. When the charging cable (while attached to the laptop) is put into the socket, the laptop makes a beeping noise, and switches on - well, something is switched on.
There is no proper boot, but I can can hear the harddisk spinning. It will stay like that, until i push the Reset button, upon which the laptop boots properly.
I wonder, what is the reason for this behaviour & is there a chance that this will damage my hardware?
At any rate, I would very much like to stop this behaviour.
Your help is much appreciated.

It seems like every time the cpu goes past 50c, the cpu turns on to full blast for 5 seconds than cools down again. Theres no reason for that, the fans should stay on low every time. This is just when having multiple tabs open in chrome, its very distracting. It just goes from 0 to 100. No ramping up the fan speed. Is there any remedy for this? Changing the thermal paste?

I have a custom pc wich has developed a fault. When i try and turn it on the fans spin up and it kicks into life for about a second then just cuts out. After about 3 seconds it then tries again. At first i thorough it would be the power supply but I tried replacing that and nothing. When you start it with no ram the computer starts up successfully and beeps implying the memory error. Also, when you boot without the 4 pin connecter going to the CPU plugged in it also starts up ok ( but without cpu ). For this reason i would think its the CPU that has gone. I have tried re beding it and the heat sink. Any ideas??

Hi there, and welcome to Techspot.

When you placed the CPU back in the motherboard, did it just slide in softly, or ..... did some pins bend?

I'd take the CPU out again and have a look at the CPU pins to see if any are bent.

When you put the heatsink back on the CPU, did you clean off the old thermal paste and apply some new goo? You need to. Thermal pads/paste are usually no good once you break that seal. You need to buy some thermal paste and after cleaning the old stuff off, apply the new.

Also, what do you mean when you say:

Hi...,

After intensive search in this forum I?m posting my problem?
I'd assembled a System in Oct 04 with OS Win2K. It worked well for an year. I decided to upgrade the OS to WinXP. While upgrading I noticed during one of the reboots that the welcome page before POST began, had shown as Celeron D, whereas the system I had built was Pentium IV 2.4Ghz. .. Anyway, I completed upgrading the System to WinXP. During subsequent restarts, I observed that at least 1 out of 5 times welcome page showed as Celeron D. Out of curiosity, I opened the heat sink to reconfirm the make of the CPU. It was marked as Pentium IV 2.4GHz. Reassembled everything back.

Configuration of my system is as below:
----------------------------------------------
CPU-Intel Pentium IV 2.4 GHz
MB-Intel D865GBF
RAM-256MB 266MHz (Now 2 x 256MB 400MHz)
Seagate 80GB
PSU 300 Watts
ATX Tower Cabinet with 1 In Fan, 1 Out Fan
LG CD writer

Now, I started facing the series of actual problems: :unch:
------------------------------------------------------------
1. The System works well, as long as I run ordinary programs.
2. Idle conditions, the CPU zone temp is 46 to 48C max. Any low end games will raise the CPU temp to 54 to 56C max. And high end games will raise temp above that & system will freeze!
3. Well the system can be used for several hours in idle condition or with ordinary software, but the system DOES NOT START even after normal shut down..
4. After norma... Read more

A:All fans spin but NO POST

The first thing I would do in this case is reflash the BIOS with the latest update from the motherboard manufacturer's site.

Because the Celeron D is a dual-core processor and the installed processor is a standard Pentium 4.

But you have only done a BIOS recovery, which is flashing the same BIOS file.

Did you get a new BIOS file from the maker's site, even if it isn't an update?

How does CPU-Z from http://www.cpuid.com/ ID the processor?

Have you checked the processor and the socket with a magnifying glass to make sure that there is nothing in the socket or on the contacts on the CPU that is making that happen?

Have you attempted to connect an external display to see if you can get some sort of display? That will help make the determination if it is the motherboard itself or if it is the screen or a cable that could be having an issue.

Hey all.

Been having this problem for a long while now. Just started up suddenly and can't remember if it occurred after installing a software or if it's something hardware related. Any help is appreciated.

Problem:
After I shutdown the computer, maybe 2-3 minutes later, all the fans (PSU, CPU, Rear + Side case) start spinning; the hdd led flickers; and if my speaker system is on I can hear a flickering sound on there too (kinda hard to explain the sound). This continues for about 8-15 seconds and then it all stops, then after another minute or 2 it starts up again and stops. This continues unless I turn off the PSU power switch.

Also, the rear case fan (think 80x80, it's the smallest size that'll fit since there's 2 mounting hole levels above that one) went out yesterday after I air cleaned the system. I went and got an Arctic Cooling 12 PWM fan to replace it, but the connectors seem to be totally different (Arctic seems to use 4 pins while I can only see 3 pins on the Mobo) so that one doesn't work. But a while later I retried the rear fan and it seems to work for now. Dunno if something was lose of it it is truly dying.

I don't know if it's my Mobo (ASUS K8N) or something else. Only things I've upgraded since I purchased this system about 4-5 years back, was the ram. Upped it from 1 GB (2x512) Kingston Value Select to 2 GB (2x1GB) OCZ Platinum.

Sounds as if something has moved in it's socket, as you moved it from room to room. Most likely the graphic card. I would power off, and lift out the graphic card and refit it. Check that, if no different, remove the RAM and refit it.

Hi,
My computer has recently encountered a problem, whereby when i on the power at my CPU, lights will be lighted up and fans start spinning. But that lasted only about 1 second. After that, everything stops. There are a few times whereby all of them will start working once again, after stopping, but usually they stopped again, with very few times successfully boot up.

I had brought it to the service center and what that guy did is remove my ram and place it back. To my surprise, my CPU boot up. However, a few days later the same problem occur again. And I did what that guy did, but this time round I did clean my RAM metal piece (I don't know what do you call the thing that attach the RAM to the motherboard). It failed a few times, but boot up eventually after several tries (took out the ram, put it back).

I had totally no idea what is going on. This does not solve the problem, as it is going to come back and haunt me once again.

I have no idea what is causing it thus I could not bring it to the service center once again, as he will tell me this if he is able to boot up my computer: "so what do you expect me to do?" It really hurts.

Desperate for help, hope someone know what is exactly going on. Thanks.
 

A:CPU boot up, all fans spin and stop

If there's a faulty connection, there's a faulty connection... There isn't a whole lot you can do... But try this:

Get a Computer Duster can (A "Can of Air") for $2, remove the RAM, and carefully put the tip of the spray extension (They usually come with a little straw thingy, stick it in the nozzle) near the RAM Slot and blow out any dust or loose dirt/debris/whatever.

Be careful and use short bursts. Too much air friction can actually cause a buildup of static electricity, especially on plastic components (I have fried many a motherboard with this... so really, be careful)

After moving my pc about to get at the wall behind it something seemed to get knocked loose inside it. When I turned it on I could hear the fans spinning and the power light was on but now signal was being sent to the monitor. I thought the graphics card had become loose so I pushed on it, even tho it appears secure and this helped it. Every so often it stops working so I do this again but I don't think the problem is the graphics card because if I leave it when there's no signal it never gets to the point where the windows start up music starts. The video signal also never goes off while the pc is on but sometimes when I have to restart when it comes back on the problem has happened. I think it's something to do with whatever hardware starts the PC up and pressing on the graphics card is also pushing whatever it is back into place but I have very little knowledge about pc hardware beyond changing graphics cards. Does anybody know what it is that might have come loose please?

My computer died on me about a month ago. The screen suddenly froze one day while idling, I tried to restart and I got no post, no display, no beep code, only the fans spin and power button light goes on.

It's an old used gaming rig, I did not build it, I got it for free 6 years ago (ancient!!) from a tech guy I used to know. I've had problems with it before and had to replace a few parts over the years, the most recent being a new Power Supply from newegg.

Anyways, I guess it's finally time for an upgrade. Money is tight for me right now and I gather it's more cost efficient to just build a new system from current low-end parts rather than buying old parts for an old system. So I plan to buy new MoBo/CPU/RAM and recycle as much as I can from the old computer (Case/Power Supply/Video Card/HDD etc). Which is why I want to know what could have caused this kind of failure in case it's one of the parts I plan on recycling. I suspect it's the CPU that died but I'm a bit of noob when it comes to hardware and I'm not 100% sure. Could it be the Video Card or Power supply that caused this?
 

A:no post, no beeps, no display, only fans spin

CPUs are actually pretty hard to hurt unless you overclock/overvolt them or physically damage them while installing.

First of all, post ALL of your parts; no one knows what you are working on except you. In addition, post the exact pw supply you installed. Just because it is new does not mean it is working or that it is a quality unit. Newegg sells high end pw supplies and they also sell junk pw supplies.

If you are intending to replace the mb, cpu, and ram, I would also add a new case and hard drive. Both cases and hard drives have come a LONG way in the last 6yrs.

Hey guys, I'm new a the HP forums so dont be to hard on me. I'm having problems with my Desktop PC Envy 700-203ed.  About a week ago I came home and I tried to turn my pc on, somehow it wasnt able to boot. (no bios nothing whatsoever) The fans did spin and the power led turned on but only for like a second and then it shut off and it tried to boot again. Again with the same results, fans spin for a second, power led turns on and boom shutdown and boot again, also no error beeps or anything like that.. I tried a different power outlet because their might be some problems with some of them (which is a different problem on its own). Somehow after I moved to the different source it was able to boot this time.. So I figured maybe it is a issue with this specific outlet or whatever. A couple days later when I was playing a game with a friend, and suddenly my pc switched off, it automatically tried to reboot after the sudden shutdown, but the same issue occured.. fans spin for a second and the power light came on and.. boom.. shuts off and tries again and again and again... So now my system was unable to boot. I've read on another post on this forum that i should try to boot without hdd and ram and other subhardware. This time I got a 5 beeps when it tried to boot.. I believe this means the bios was recoverd (rolled back the bios driver or something and please do correct me when im wrong about this) Next I reattached all the hardware... Read more

Greetings, Could not find product specs on your PC at the HP Support site. However, I did find some specs elsewhere. Did your PC ship with Win 8.1 64 bit OS? It appears to have been introduced by HP sometime in 2013 or early 2014. How much time elapsed between upgrading to Win 10 versus the onset of your problem? The intermittent problem you are experiencing could have any number of causes. Is the PC continuing to boot successfully or booting when it wants to since reattaching the hardware you disconnected? I am unable to determine this from your problem description. Exactly what hardware did you disconnect? You have to systematically troubleshoot each component and eliminate it as the cause. The first item to tackle is to run a check disk. Then run UEFI boot time hardware diagnostics. Then reinstall or update the graphics drivers. I can provide a general flow to use to troubleshoot the other components. Let me know if you are interested. Cheers!

After troublshooting an Inspiron 620 which was not displaying anything on monitor and not posting I decided to remove the motherboard from case and attempt to fire the system up with only power supply, memory, CPU, USB connections to board plugged in. I deliberately left the case power button jack disconnected and used the tip of a screw driver to momentary short the power pins on the board. The system booted straight away. It seems whenever the case power control pushbutton wiring jacket is connected to the motherboard, the system would only spin the fans and not successfully power up. I disconnected the black "loop" wires on the power button jack and it now starts up. Does anyone know what those looped wires are on the jack?

So I was watching a video from my 'Nix box last week while running some pretty heavy CPU intensive apps and the computer froze on me twice, My CPU never freezes so I thought that it was odd but the PSU and GPU were running a little hot so I thought I would tone down the usage as I had just installed some new cooling fans a day before and a new CPU about a month earlier. Then the computer shut down and wouldn't start back up. I replaced the PSU originally thinking that since it had been running hot maybe it just died. Installed and no power no fans nothing. Replaced the mobo with the same results, I'm at a loss right now as to what the problem could be. I even switched out the push button in case that burned out somehow and nothing. Any ideas where to go from here?

Update: just an update after posting I found the POST walkthrough and followed it step by step and still nothing. Would a bad CPU cause there to be no power through the whole board? I replaced the CPU fan as well to be sure and I can't seem to find any other possibility.
 

A:Computer shut down, no reason, no fans spin, new PSU and mobo

Yes a bad CPU would cause the board not to function, but bad CPU's are very rare unless they are damaged by handling or installing. What type of CPU is it? The socket type can matter for damage

I went to take a look at a Dell Dimension 4700C (pictured below). The power switch on the front doubles as a power light, which was blinking a steady on-off-on-off. When you pressed the button, you could hear the CPU heatsink spin up, slow down gradually, until eventually it wasn't spinning at all. While the fan is spinning down, the light adds an additional blinking in (almost looks like it hard drive activity).

The entire time nothing appears on the monitor. You can hear the hard drive spin up when you hit the power button but it's brief and spins back down pretty quickly. From the moment you press the power button till the time it's finally powered down, about 15 or 20 seconds goes by.

Part of me is leaning towards this being a power supply issue. It's not your standard power supply, but a long slim one (which I really can't see how to remove properly). The inside of the computer had a moderate amount of dust built up and after thoroughly blowing it, the same problem persisted.

For what it's worth, I took a video with my cell phone of what happens after you press the power button (3GP format inside a zip file).

So I've been abroad and my computer hasn't been touched for 6 months and it was brand new before I left. When I started it today it worked for 15 minutes before freezing. Then it wouldn't boot past the BIOS screen. Now the monitor doesn't even respond but the fans spin really fast and constantly until I manually turn it off. Needless to say, I'm gutted. HELP ME PLEASE! I already tried reseating everything and removing the mobo battery.

SPECS:
CPU: intel i7 920
MOBO: ASUS p6t
PSU: 650W seasonic S12
RAM: 3x2GB kingston
HDD: SATA-300 1TB 32MB samsung
CASE: CM690
GPU: MSI GTX 275

Thanks

Replaced failing Radeon 5770 with Radeon 6770 and now it won't work.

Motherboard LEDs turn on, CPU and case fans turn on. Graphics card fan turns on and then keeps cycling faster-slower every five seconds or so. No signal through VGA or DVI.
The problem persists even when I put the old card back in. What could have gone wrong?
 

A:Tried switching HD 5770 to HD 6770, fans just spin and no display

Any ideas, anyone?

Tried:

Reseating RAM
Resetting CMOD
Reseating both cards
Different cable from PSU to card
Dusting all components thoroughly

I have a HP Pavilion dv6 dv6-3122sa
Windows 7 home premium (64 bit)

I've had it for about 8 months, and then today all of a sunden whilst ~I was browsing the web, it started to freeze and was taking ages to load/ respond to clicks. [I did not install anything today, did not download anything, was not opening an email] I was literally just browsing the web like I always do, and out of no where it started playing up.

Then out of no where, I got a blue screen saying there was an error- if this is the first time I've have received this error just let it restart. And it was the first time, so I did let it restart.

But now it keeps going to a blank screen, it as a blue background picture with white rays and I can move the cursor but nothing happens. In other words The screen background just stays blue with white rays, but I can move the cursor.

Just as soon as it loads up to the screen background that just stays blue with white rays, there is a loading bar on the cursor, followed by a transparent grey pop up box that appears for about a second before vanishing.. then nothing happens. I can move the cursor that is all.

I've tried restarting/ taking the battery out etc no joy..
So I went to start up repair (normaly I would get a wizard that gives me the chance to do a system restore)
Anyway it does the same thing, it takes me to the blue screen,shows a grey transparent popup box for a second before disapearing.

A:HP laptop will turn on, but screen stays blue with moving cursor?

Can you enter into safe mode? Normally by hitting the F8 key on start up. Then you can select safe mode with networking and go look for the latest video driver for you system and check to see if it's better than or the same as your current driver.

I've had my inspiron 15 7567 for little over half a year and have already had several major problems with it, all of which have been able to fix myself up until now.
When the laptop enters sleep mode(either by closing the laptop, or entering it manually) the fans kick on at full speeds, and remain on until i open the laptop again. I have also found that the fans will do the same thing even if my laptop is completely shut down, as long as it is plugged in.
Any help or suggestions would be appreciated, thanks.
