Are there any decent 'beat up the cpu' test I can run to see if I can 
peg the heat?

I am doing screen off tests, so it is running nice and cool right now!

There is something not right about power management on this system for 
sure.  Thing is it is hard to find a decent 12" monitor / duo core / 
keyb with pointer notebook for cheap.  This is now my fourth? x120e and 
as much as I dislike them, I have not found anything else that I can 
afford.  Particularly if I get cut at the end of the month as things now 
stand.  So I have to work with the 2 systems I have...

No.  It is REALLY easy to pull the drive; that they did nicely. Getting 
to the fan, for example is a real pain.  Had to do that on the first one 
of these I owned.

Probably just a poor design for when the unit is going full out.  It 
works OK if it is half-way being used, not at full CPU demand.

OK.  I will have to work with that.
