Toshiba satellite a75-s229 notebook problem

for some reason, my friends laptop shuts off out of no where. we are pretty sure its a overheating problem because rite now we have a HIGH power fan under it and its fine but when it doesnt, it turns off randomly. Is there a utility that i can get to change how many degrees it takes till it shuts off, if thats even the problem?

eek.. are all the fans working? yes it sounds like a over heating problem... i would not turn up the turn off temp as you coud fry the cpu if it gets to hot.. cheak the fans and see if thay are all working and cheat for dirt and dust..

ya, its probably just dirt and dust, the fans are possible upside down as well.

did i say that? i think someone changed my post..

You never would want to change the temp. it shuts off at, that is set that way for a very good reason.

i have the same unit with the same symptoms(overheating and shutting down).
i went and brought a can of compressed air and blew the fans out and especially the copper heat sink at the rear(the heatsink fins are very close together and trap dust easily).
i did this with the unit on so it blew the dust out and not back inside the machine.
this seems to have fixed it, been givin it a floggin for bout 5 hours now, normaly it wouldnt last ten minutes.
