Gateway randomly shutting off (overheating?)

Hi everyone. I have a Gateway T-1625 that has started shutting of
randomly. I noticed that when it shuts off the bottom of the laptop i
really hot, hotter than normal. I'm guessing it's overheating. I'v
run some different utilities to see what the temps are like while doin
stuff and it will go anywhere between 65C and 90+C. I took off some o
the stuff from the bottom of the laptop to make sure the fan was workin
and it is so I'm not sure why it's suddenly began overheating an
shutting off. Any ideas on what to do? On another forum I saw someon
suggest to another person having an overheating problem to put som
arctic silver on the processor. I actually do have some and coul
possibly do that if you all think that might help. Somebody els
suggested updating the BIOS because maybe it will fix a fan issue or
processor issue with the processor not throttling back to cool off
bit. Let me know your thoughts.

PS - While on this form the temps been hanging out in the mid to uppe
80's. I'm not doing anything on the laptop but this right here

 

10 degrees shy of boiling seems excessive! If you get to the point of
tear-down...you will probably find the heatsink clogged with dust.

 

Think "compressed air" as a first step.

 

Hi all. So it's been a month and a few days ago this all started u
again. I've noticed that every time the temp starts going up it will g
down immediately if I unplug the AC adapter. Any thoughts on what migh
be wrong

 

Sounds like the AC power supply is what's overheating. Either it's
failing, or the excess heat is causing something else to fail. Might
need to replace the power supply.

Or the battery could be going bad and drawing too much power. Try
running it without the battery and see what happens.

Oh yeah, I don't know what kind of processor you have, but some Intel
and AMD processors can change speeds. And depending on the power
options, it could be set to run at full speed on AC and low speed on
battery. And running at slow speed, the processor cools down really
fast.
