Sleep/standby: how do I know if this is the state my machine is in?
Kernel 22.214.171.124, Slackware 12.0
I do not know if the main integrated circuits (aka chips) on the motherboard can be put in a low power consumption (LPC) state, and this doubt includes the CPU itself. A couple of questions:
(a) Can the OS put the CPU in LPC?
(b) If it can, how do I know, at a given time, that the CPU is in LPC?
Perhaps a fairer question would be: how do I know the CPU will be put in LPC at a given time. At any rate, I presume it would be the kernel who would signal the CPU to go to minimum power consumption.
