I manage a couple of hundred GX260 desktops by Dell. I normally don't have any problems with setting the power options on the pc to never suspend or hibernate. However, I have 3 that no matter what I set the power options on go into sleep or hibernate.Once they are suspended it takes 3 or 4 reboots to wake them. I tried setting the BIOS setting to S3 and checked all my desktop settings but I am stumped on just these 3 units. Unfortunately the warranty has expired and I cannot contact Dell for a resolution. Does anyone out there see what I so clearly do not?
