Every time the monitor turns off the display (when not in use), it is impossible to wake it up. I need to restart the computer every time… it is frustrating! There is no problem with the computer, it is just the monitor that doesn’t seem to receive the signal back from the computer when it resumes activity. The same happened when switching users.
Can anyone tell me if it is a problem with the settings in power options? Or is it the configuration with the monitor (Dell 24 inches E248WFP) or the video card (768MB nVidia GeForce 8800 GTX)?
Thanks a lot for your reply, but unfortunately I could not find the S3 vs S1 option (definitely nothing on power options). I believe I searched in the right place.... Any other suggestion?
According to your manual here
you have 3 options in the bios to check/set...Low power, suspend and Quick resume..
These should be under the power management section of the bios.

What I did was to change the power options S1-S3. Unfortunately though, I rushed a bit my enthusiasm by saying that the problem was solved. Because I tried it once (made the power options changes, put the computer to sleep and then waked it up almost immediately) I thought it had worked. But the problem persists: I am unable to wake the monitor up after it has gone to sleep or anything else that turns off the display (including switching users).
I have tried many things: updated drivers, updated BIOS, changed power schemes. Don't know what elso to do. I have also contacted Dell Support but they are running out of options. I really need some help here.
My impression is that there is something wrong in the configuration of my system. Otherwise, I would assume that it is a very common problem, but I haven't heard of anybody else sharing the same problem (so far).
Now I have my computer with the sleep feature disabled, as you suggest, but that doesn't fix the problem when I try to switch users (and also, in terms of energy consumption, is a very expensive solution!).
