thank you for the tips!igalan said:For hibernation to work, all hardware must be able to support it. That includes PCI cards. It's possible that you have a PCI card which don't support it making the computer unable to hibernate (an old TV tuner for instance). With my Asus A7N8X Dlx (1.04) I was able to hibernate, but suspend didn't work (S1 or S3). There is a tool from MS to monitor this process and see where it fails, it's the same that optimizes boot speed.
therefore a modified version of Maschine`s WakeOnLane tool could be a great alternative to the hibernate mode.
