^^^^ oops, original, not this one
Siegfried certainly advertised the many shutdowns/slowdowns/"freezes". I just hypothesized:
<pats self on back>
"I wonder how/whether the percentage calculated is affected by power management
that slows down the CPU clock to keep it cool? Wonder if that could be happening.
I've never looked into power management stuff. I guess there is a temperature
where it just shuts down too, to protect itself?"
</pats self on back><Need it today ;-p /> RPM1 was apparently also onto it when he
cryptically said, "Just curious, is your laptop a Hewlitt Packard?"
