I want to wake-up my PC by USB keyboard connected through PS/2 adapter. According to BIOS settings:
Resume From S3/S4/S5 by PS/2 keyboard ... [Any Key]
it should be working, but doesn't.
If I connect USB mouse as I did for keyboard & set up in BIOS:
Resume From S3/S4/S5 by PS/2 Mouse ... [Enabled]
it works - PC wakes-up when I pressed a mouse button.
Is it possible to wake up my PC with my keyboard?
Check PS/2 standby power jumpers on the motherboard. Try another keyboard. Try to light some of the Caps/Num/Scroll-Lock lights and get you PC into standby - if the lights go off then either your motherboard or your keyboard does not support this mode. Your keyboard may require more power than your motherboard supplies in standby mode. It is also possible that your motherboard resets your keyboard before turning it off, so the keyboard cannot properly detect if it is connected to PS/2 or USB port. – Jack White – 2016-07-19T16:09:04.177
