Hi Jeff and all,

I concur with Tom. Most likely possibility is the rug of dust and hair
you're going to find blocking the exhaust vents. You'll need to open the
machine to get to that. Blowing air into the system will dislodge some or
most of the rug, but its still in the system. Everything Tom said is
mirrored in my experience. I also run a shop, and we specialize in
notebook repairs. Good clue with the fans changing speed and probably
frequency. You should replace the processor's thermal paste as old paste
could be the cause of or another symptom from the heat.

Hi Jeff,
In my experience it is a dirty air intake. I get a few of these in shop
for the same reason and this is the most common problem. I take the
thing apart and blow out the air ducts, I have an air compressor but
canned air will work. I sometimes have to remove the heat sink and clean
it and the cpu with alcohol then reapply heat sink compound ( I prefer
Arctic Silver *http://tinyurl.com/8mod5* )and reinstall the heat sink.
Careful removing the heat sink, make sure the pc is hot so the old heat
sink compound is soft, then carefully insert a small thin putty knife
between the heat sink and cpu so as not to pull the cpu out of the zif
socket . Sometimes it is nearly impossible to avoid pulling the cpu out
without the heat sink sticking to it. Just be careful don't want to bend
any pins they are difficult to straighten and break if you even look at
them. Old batteries run hotter so it contributes to the thermal load so
this may be a problem as well. Maybe a new battery if this one doesn't
hold a charge or lacks capacity.
