This my output from sysctl and apm when running on the lowest clockspeed:

This is the output when i use apm -H:

hw.sensors.acpithinkpad0.fan0=1972 RPM
hw.sensors.itherm0.power0=6.00 W (CPU power consumption)

The energy consumption is the same which is odd.
Are you running with the latest bios (1.40-1.15) from Lenovo?
Yes it is the latest bios.
Hmmm. Smells like a bug, to me. But by changing hw.setperf your
self you should be able to go to other speeds(?). And of course, the
real test is to see if you get longer life at setperf 0.

It seems like that's the same output. If the processor throttles down it
should also consume less energy, but it says 6W all the time though.
