This Toshiba Satellite A135-S4656 laptop was given to me with the complaint
that it shuts off after a few hours. I had it on for a few hours last night
and it worked fine. The owner said that before it shuts off, the mouse
pointer starts behaving erratically and the entire system slows down. To me
this sounds like the heat sink might be getting clogged with dust causing an
overheating problem. I also noticed that the fan is quite noisy at times and
you can hear the speed vary. Before I take it apart I'd like to know, are
there any other common issues with this model that would cause shut down
problems?

Sounds like a fan/dirt/heat sink compound problem.
I've found thick gun oil to be good for noisy fan bearings.

from your excellent description it sounds like you need to replace the fan along with cleaning any dust accumulation in the heatsink ... fans go bad from wear and there is no way to lubricate them back to being operational except for maybe a short period of time ... try to find an original replacement fan because most of generic replacements are junk and will not last.

I was able to remove the keyboard after lots of nudging with several small
screwdrivers. I'm not down to the bare motherboard yet but at first glance,
I don't see much dust in this case. A new fan is going to be at least $20. Throw in a couple of hours for labor and testing and this nearly seven year old laptop may not be economical to repair. The part about the erratic behavior of the mouse makes me think that there may be an additional hardware failure other than the heat problem. Thanks for your reply.

Also around the intake on the bottom of the machine. Hit it with compressed air and watch the dusty fly.$6 if you don't mine used. \$15 for new.

Right. Just toss it because you can't find a way to get rich fixing
it. Repair is always better than recycling:

It's caused by either too many mouse drivers installed or a broken
"enhanced" pointer precision:

Hi Jeff,

First of all, I value your opinion quite highly. I mentioned the "not
economical to repair" part because I wasn't sure the motherboard was stable.
I try as hard as anybody to keep things running for as long as possible.
Since you said it's more likely the mouse problem is a software issue then
the motherboard should be in good shape and it will be economical to repair.
I didn't want to go to the trouble and spend my customer's money and time
replacing the fan and finding out a few weeks later that the motherboard was
not stable.
