Note1: The backlight of LCD should be off when WOL from S3 as it is remote wake up.
Note2: the S3 -> S4 transition results in the system transitioning to the S0 state first so OS can
save the context to the hard disk. The system BIOS/KBC will not be involved for S3 ->S4
transition. The system power scheme will wake the machine from S3 and then transition to S4
Hibernation. The backlight of LCD is off during this transition.
