If you don't engage
apm on newer Compaq laptops, the fan will NOT start regardless even
if you tell the "bios" (and I use the term lightly since the Compaq
BIOS has very little to do with anything happening on the HW) to run the
fan ALWAYS when on AC power. And I know for a fact that the n610c
will overheat VERY quickly. If there's any consolation, at least
it's a P4... so it shuts down before frying the CPU.
ACPI doesn't work on the newer Compaqs... turning both off leaves
you with NO FAN. With just ACPI (though a newer version of ACPI may
actually work... but nothing in any shipping dist that I know of),
the machine will not operate correctly.
Note: The n610c, even with apm and running the fan full blast will
eventually overheat the HD. Just fyi. This laptop needs some
redesign work. You might not have this problem unless you have
