Dear Ridly,

Greetings, this is ASRock TSD.


We have validated this function in our lab with a PS/2 Keyboard and it did work.

Please notice that this function only works with PS/2 keyboard, USB keyboard is not supported.

Please enter Device manager > your PS/2 Keyboard > Power management and make sure "Allow this device to wake your system" option is checked.

If PC stills no response with this feature, please load BIOS default and only set PS/2 keyboard wake to enable to verify.

If possible, please use other PS/2 keyboards to verify.


Thanks!

All the best,
ASRock TSD
