I have a customer who brought in a Sharp Actius Pc-RD10 laptop with random shutdowns.  I tore it apart to find the thermal grease between the cpu/heatsink practically non-exsistant. So i cleaned the heat transfer surfaces and applied a fresh coat of thermal grease. put everything back together, everything wasworking the fan is working perfectly so I then proceeded to reinstall Win XP and about half way through BAM! it just shut itself off!

 

Why??  Anyone have any ideas/ sugestions?

 

thank you!

Well...thermal grease is supposed to be barely applied...it's not like greasing auto wheels or whatever.  It's possible that you have have too much on, I can't tell from reading.

 

Eliminating that...the logical culprit would be the PSU or corresponding component in a laptop.

 

Did you check any temperatures at all when it was working?

taking it apart again....i see i may have too much thermal grease on there. i took out the MOBO to have a closer look at it to see if maybe i missed something.as far as chacking the temps, i have no way, and there is nothing in the BIOS that checks the temperatures being that the laptop is over 12 years old
