Comment 240 for bug 355155

For those of you experiencing both overheating and sluggish/freezing
behavior under DELL E-Series laptops (possibly also some D-Series), I
finally discovered the whole thing could be explained by some heat pipe or
fan-related issue that many of those laptops experience! See the subject:
http://en.community.dell.com/forums/p/19247293/19398983.aspx
So far, nothing seems to help (BIOS update etc), so it seems some of those
laptops need to be send back to DELL for repair. Also, since the problems
worsen with time, it is highly possible that those heat pipes are full of
dust.

This might help dividing this thread into people with real software issue
and those with hardware problems experiencing the same symptoms.
