Hi

I have a dell inspiron 7010 with windows 7. It was running hot so I took it apart and put new thermal pads on it. Now when I turn it on it runs for 10-20 seconds and shuts down. Any ideas on what the problem might be?

thanks

Might be the Power Supply Unit. Is it a laptop?


I prefer Linux. Windows 10 is just to invasive for me.

Ok try disconecting the battery from the computer and leave the charger in. Start up the computer and see how long it runs. Tell me EXACTLY what happens when it restarts.

Does it take less time to shutdown every time you start it up? It could be overheating really bad

Were the new thermal pads the same size as the old ones? Did you use any thermal compound?

same thing starts up and then shuts down after getting to windows splash screen.

sort of, got to windows splash screen first then shut down after almost through dell splash screen then seemed to shut down almost the same after that.

the thermal pads were the right size, I did not use any thermal compound.

Hey krazyace,

 

I'm almost 100% it's an overheating issue.

 

If the CPU passes a certain temperature threshold it's designed to automatically turn off to prevent damage. And if the cooling wasn't adequate, that's what I'd expect to see. It'd start up, but heat would quickly build up to the threshold level, and it would soon shut down.

 

I'd try reapplying the thermal pads. When you removed the factory ones was there thermal paste on them? If so, you should use some too when you reply them. The paste is important to properly conduct heat and draw it away from the component.

Ok, I took off the pads and put some paste on, it is working again.

Thanks.
