[arch-general] Monitor not going to "power save" mode in suspend

[Madhurya Kakati]

Hi,
I am using pm-utils to suspend-to-ram and suspend-to-disk. In both the
suspends my LCD monitor goes black but doesn't go to the "power save
mode" i.e the light doesn't turn orange. This happens only in
archlinux though. On Windows when i standby (suspend) the monitor
properly goes to "power save mode". Also in both the OS I can't wake
up from suspend-to-ram by pressing any key on the key board or moving
the mouse. I have to press the power on button on the CPU cabinet. I
guess theres a BIOS setting to enable that but i can't seem to find
it. Please tell me how to solve both the problems. My motherboard
model is Biostar TA785G3 HD and BIOS is AMI BIOS.
Thanks.
