Next, one responder mentioned that a laptop
is the wrong CPU to do the heavy lifting on
anyway. Massive use of the cpu on a laptop
can cause overheating, which I recall will
then cause a smart cpu these days to drop
its clock speed.
That's scary. Could anybody confirm this? Even when the
plugged with AC power?
The power source is not the issue. It is not a
battery issue. It is the amount of heat generated
by your CPU. Since laptops have no active cooling,
they can overheat. And a CPU running flat out
will apparently generate more heat than one
in a no-op state.
I can testify to this. Our sales/support guys all run our
software on laptops, since mobility is required. And being
competitive sales types, they all want to have the fastest
machine - there are regular sulks when one of them blags an
upgrade. However, the "fastest" machine varies from day to
day and there are constant complaints about machines
slowing down.
