[coreboot] Can boards wake up from S3/4/5 by specific keystroke

[Zheng Bao]

All,

Some customers says ThinkCentre M6600q (lenovo) has the feature of wake up the system by pressing ALT-P on USB keyboard.

I am wondering how it is implemented? Is it done in chipset, BIOS, or a special keyboard?


Or when the BIOS wakeup, it reads the keystroke to see if it matches the pre-defined key. Does it sounds reasonable?
