I have a Dell desktop with Windows 8 and it will wake up from sleep mode if not in use for awhile but if left for longer periods it goes into sleep mode and will not wake up. I have tried to wake it touching mouse touching power button using windows key + C no results unless I do a hard power down Now it has started to download windows updates without installing them The best I saved for last...it will not shut down it only goes into Power Save mode very frustrating...suggestions please?

Finally found a "workaround". I noticed that everytime this happens and after I do a hard reboot. There's always a Windows Update. So, I turned off Windows Update. And it never happened again. :)

Just manually install your updates daily. The auto-update causes many problems.

Same problem here on new sony vaio pro 13, happening multiple times a day (about 1/2 the time it enters sleep) since a recent bios update haven't tried windows update changes but maybe I will. planning on sending it in for repair hopefully sony can fix something anyone else have any other suggestions?

once i had the same and i sort it out by disabling some power management option inside my dell optiplex 760 bios, i cant tell you the exact option but it was inside power management section, try doing the same.

Was having this same problem and I fixed it. Check to make sure it's actually not waking! In my case the computer itself was waking but the display adapter was not. I could hear the processor fan come back on, the hard drives spin up, but nothing on my screen. In my BIOS, there was an option to not let the integrated graphics adapter sleep. It was called "RC6 Render Standby" and I turned it off -- fixed!
