C840 laptop chronically overheating
I have blown-out and dusted the interior of the case with a feather brush, reseated the heat-sink with lots of paste, reseated the heatsink with a thin layer of paste, I've disabled speedstep in the BIOS to get the thing to run @ 1.2ghz instead of its' rated 2.0ghz, I've cleaned and lubed the fans with 3-in-1 oil...
yet...
she still overheats.
It goes like this. I'm running Slack -current BTW.
Boot ok...
XFCE4 starts ok...
gkrellm starts ok...
THM shows anywhere from 28 to 44C at this point...
Konsole starts ok...THM kicks up to 48C
Seamonkey starts...THM kicks to 50C
load a youtube video to give the processor a workout
within 2 mins THM spikes to 74C and fans start...THM drops to 50C within a minute or so and then fans stop...
just let the machine sit for a minute...and...lockup
hard reset
THM shows 66C during boot sequence
this pattern repeats every time I try to use this machine.
Is it possible that the processor has suffered damage and needs replacing? I need some hints or clues here...
