Solved Why is my laptop turning on and the shutting off right after

June 27, 2019 at 11:49:11
Specs:
A while ago I realized my laptop turns on for a few seconds and then shuts itself off. I tried many things throughout a couple of weeks that worked but only temporarily.

First I took out the ram and battery and then reset the laptop by holding the power button for 10 seconds. After that the laptop worked but only for a day. The next day I opened it up and removed the cmos battery and reset the laptop, again, it worked but only for a day. Next I went to the store and bought a new cmos battery, I replaced it with the one inside, reset the laptop, and then it worked but only for a day.

I’m running out of solutions here so if someone knows more about this sort of problem than me or if you’ve gone through something similar please let me know what I can do to solve this problem, thanks.

"Did you remove or disturb the CPU heatsink when you opened up the laptop? If the heatsink isn't installed properly, the CPU can reach the auto-shutdown temperature in a matter of seconds."
That would be my thought as well.
Remove heat sink, clean off all thermal compound, reapply with correct amount:

Most likely overheating & shutting down to protect itself from burning out. Either the cooling vents are clogged or the CPU cooling fan has failed. Try blasting compressed air thru the vent openings. If a cloud of dirt/dust blows out the other end, you've probably found (and solved) your problem.

I don’t think it’s overheating because it’s never hot, usually always cool even while running games but I’ll try it out and let you know what happens.

You say it turns on for a few seconds and then shuts off but whenever you opened it up to do something it would then work for a full day. Is that correct? How old is it--model #, etc?

It'd still be a good idea to blow any dust out while you've got it open--you can't necessarily go by how it feels. Does it have any temperature sensing ability? Can you tell if the cooling fans are spinning?

DAVEINCAPS I blew the dust off of the fans (there was none) and tried turning it on and it didn’t work.

The laptop is a Sony vaio SVE151D11L and I believe it’s a 2012 laptop. And yes I can tell that it’s fans are spinning, either way it wouldn’t be a heating issue because it’s trying to turn itself on from a cold/cool start point.

Have you tried booting into safe mode?

Did you remove or disturb the CPU heatsink when you opened up the laptop? If the heatsink isn't installed properly, the CPU can reach the auto-shutdown temperature in a matter of seconds.
