Reapplied thermal paste to the heatsinks in my P151HM1 and now my system will automatically shut down after a minute or two.

Well I took apart my Clevo P151HM1 because I was getting the dreaded artifacts/kernal crashes associated with the vid card. I removed the heatsinks from the cpu and gpu, blew dust out of the fins/fans, cleaned off the old paste, applied new paste, and tightened everything back up. But now, when I boot up the machine it'll automatically shut down after about a minute or so. I should time it to see if it's always the same amount of time, but I'm certain it is. Doesn't matter if im in the bios or booted into windows.

I did forget to remove the battery when I was reapplying thermal paste/cleaning the innards, so I don't know if that may have done something

 

I once cleaned my machine while keeping the battery in and it scared me to death. But thankfully my machine worked fine after that. I did NOT disconnect/reconnect anything except the fans though... so I can't say. It might be the reason. You should check if the fans are blowing out hot air when you turn it on. If they aren't, then overheating is likely it. But the fact that you can get into the BIOS means you can probably get it working.

Either way, contact your warranty guys and see what they say.

 

Fans turns on. GPU fan turns on instantly, while the CPU fan takes a little while before it gets going, but it does indeed start up (not sure if that's normal as I never noticed it when it was working properly). However I tried running it without the CPU heatsink on it and it shuts down roughly the same time, so I don't think it's heat based.

 

im no expert but you could well have blown something on your mother board having the battery connected. sadly all it takes is one spark.
ive heard of problems before while the battery was removed but the person had not drained all the power by pressing the power button for 10-15 seconds first. im guessing you didnt have an earthing cable connected to your wrist as well did you.
open it up again and remove the cmos battery for 20 seconds. please remove the battery first though.
cant guarantee it will help but its worth a shot.

 

Nope I did not have an earthing cable :\

Anyone know where the cmos battery is located on this laptop?

 

no idea but if its like other models its under the keyboard somewhere. they dont make it easy to get to.

 

If your fans work right, have you tried running it without the battery installed? And with only the battery (no power cord) as well? You gotta do some basic elimination; make sure it's an internal problem not related to power or heat. Since you've already ruled out the fans and it isn't bluescreening, power may be one of the issues. Unless you send it for an RMA (and HOPE it's covered to fix under warranty), then you best get to playing guess the problem. If you can figure out what it is, you may be able to get the right fix without an RMA, even if you need a new part.

 

Yeah I tried it with both just the power cord, and with just the battery. Shuts down at approximately the same time. I am still under labor warranty, but parts has expired a few months ago. I'll have to send it in if the cmos reset doesn't work.

 

Good luck then.

 

Just curious, why is the reason to removing the CMOS battery to repasting the heatsink? I've never done that and never ran into any problems when building a new computer, removing CPU, repasting thermal paste... etc. I've never even heard of people advising to do that too.

 

I was referring to removing the laptop's main battery not cmos battery in my initial post.

 

but i wasnt.
did you leave the battery connected Mighty_Benduru.
i suggested the cmos as ive seen a cmos reboot help with lots of problems in the past.
maybe leaving the battery connected has shorted something. just a small screw dropped onto board can cause a short.
as i said in original post im no expert but its worth a go before a rma which could cost mega money as op is only covered by labour.
unless you have any better ideas on what to try next.

 

Oh I see. Then that will make sense. My bad. Yes, I've heard of CMOS rebooting helping to resolve mobo crashing issues. I thought it was removing the CMOS battery when reapplying thermal paste. That will be a big pain.

 

It also resets the EC which can get corrupted if you get a short.

 

exactly what i meant but in a long winded way

 

Did you try reseating the heatsink of the GPU, too?
Maybe the heatsink doesn´t sit in the correct position, and then the GPU gets too hot and shuts the system down. I had this once, that´s why I am asking.

 

Nope. I will try that as well.

 

This sounds like the most probable cause. I've done something similar with a desktop cpu. Sometimes it isn't seated properly, sounds like thermal protection.
