Hi,
ok, it's clear. But isn't it true that in the periods with clock stopped
the CPU consumes much less power than in those with clock running ? Why there
is no at least slight power saving effect then?
BTW I'm experiencing the same. p4-clockmod also doesn't save power on my
Clevo D610SU notebook.
With regards, Pavel Troller
