With a can of dust cleaner, available at any computer store, blow back
through the *exhaust ports* to remove dust from the heat exchanger on
the cooling pipes. Do this thoroughly. You should see an immediate
improvement. The next step is to find out how to open the case, remove
the keyboard, remove the shielding, and have a good look into the heat
exchanger inlet. Many of these laptops accumulate balls of fibers or
even a mat of fibers covering the heat exchanger inlet, on the outlet of
the CPU fan, and this *must* be removed.
