 Hi,

I'm a newbie, and trying to understand the power control over linux.

It looks that the basic power control would be achieved by /sys/power/state,
but I can't find the starting point to look at it.

Could somebody help me to find where takes the input from /sys/power/state
in linux kernel code, please?

(I've posted this before, but it doesn't look it appear in the list, so I
re-post again.)

Cheers,

- Joy
