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 spe=
cial keyboard?

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

Zheng
