Hi.
While reviewing 2.6 on my laptop, I noticed something very odd. Average power consumption is about 200 mA higher compared to 2.4.
I measure this via the /proc/acpi/battery/*/state interface.
Under 2.4, when idle my laptop consumes about 720mA, sometimes even below that.
Under 2.6, the average idle power consumption is about 900mA.
iN both kernels, I have set Performance state 1 (400mhz) before measuring the average power consumption.
Can anyone confirm this observation?
If so, what is causing this? 200mA is quite a lot of difference, and if this is a true measurement (no ACPI bug), this might be a serious problem for laptop users.
