The last thing you can try is try to reconfigure your BIOS. There
are some settings (I have no desktop currently) that enable/disable
S1/S2/S3 states and change ACPI/???'s version. Disable legacy USB
support (be sure to have PS2 keyboard just in case) and... try...
A friend of mine got his PC suspending to RAM after changing
something in the BIOS, but I never asked what exactly. Luck.
Thanks, Doncho. After having changed from S1 to S3 in the BIOS, my
computer can suspend to RAM. However, I cannot resume it: I use the
power button and I see activity in the computer, but the screen
remains black forever. Any ideas?
