I put the thermal past. I'll check for an update. Expenditures are "urgent only" for the time being. :-( The cooling unit has a pressure plate and liquid conduit tube to the heatsink. > > > But the fan had to be in on the bad information too.

It always does. Thereby a constant 85'C was a misreport. Things were more likely either normal or approaching 102'C, the red line. That blowing out some dust fixed it only confuses things, really. :-) > > > BTW, this is a Pentium M, 1.6 GHz., which is suppose to handle heat > > well. > > IIRC, Pentium M saga was not very "wattage hungry", I mean, it had a very > low TDP (<30W) :-? This one is 24.5W at 0.956 - 1.484 V. It steps at .6 .8 1.0 1.2 1.4 & 1.6 . I really like these machines, two little Dell Inspiron 600m's. Of course, at 5 & 6 years of banging around town with me, I have to expect maintenance like this. The other is headless but runs a 1440x990 desktop LCD without problem. -- Kind Regards, Freeman Microsoft is not the answer. Microsoft is the question.
