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?

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!

    I have a brand new Acer Aspire S7-392 doing the same thing.  Goes to sleep--can't wake up.   I thought it was an Acer problem and have been on the phone with them several times and we were not able to fix the sleep problem.  I was ready to send this computer back even though I really love it otherwise.  Now I'm thinking maybe this is a Windows problem and I should wait for a fix.  I have tried many of the suggestions in this thread and none of them have worked.  Is Windows going to find a solution to this problem or should I go buy the MacBook Air that I was considering since Windows 8 is on all the new computers?  This is frustrating.  Please help!

    Me too. Dell Inspiron 7000 series. Updated to Win 8.1 Fell asleep while I was downloading a huge and very important file. That hurt! Changing the power plan does NOT help. I currently have NEVER SLEEP with or w/o power plugged in. Please fix immediately. I have applications that need run all day whether I'm with my laptop or not. Thx!

    One way that I make sure that my computer doesn't go into sleep mode when I don't want it to is to run a nifty little program named Mouse Jiggler ( https://mousejiggler.codeplex.com ) .  When run this program simply generates "fake" mouse input to Windows, which jiggles the mouse pointer back and forth.  Mouse Jiggler doesn't need to be installed.

    Just to follow up, updated with Windows 8.1

    It changed the startup background.

    Set the power settings back to try sleep mode. Will report on the results laer.
