This Toshiba Satellite A135-S4656 laptop was given to me with the complaint
that it shuts off after a few hours.

Sounds like a dying fan or it's clogged with dirt. If you're going to
tear it apart, you might was well replace the fan.

One common problem with this style of fan and associated heat pipe
radiator is that dirts, dust, and hair get stuck BETWEEN the fan
outlet and the radiator fins. Tring to clean out this dust with
compressed air blowing inward or outward doesn't work. The filth gets
stuck in place and needs to be mechanically removed with a brush,
tweezers, or scraper. Photo:

The heat pipe radiator is to the left of the fan. The dirt is
probably in between the radiator and the fan.
