Years ago I found a way to disable sleep mode in Windows 7 to prevent users from making their machines inaccessible. Now I need to re-enable it and have not found a way to restore it. Sleep is grayed out in the shutdown options and is no longer listed under any power plans.

  • This is not a GUI setting in control panels. That's no longer available. It was probably a registry entry, a group policy, or via the command line with a tool like powercfg

  • It is not fixed from options under Administrative Templates/System/Power Management/Sleep Settings

  • Trying to force a timeout such as powercfg -x -standby-timeout-ac 10 fails
  • This was done on each workstation, not through a domain GPO
  • Check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power. – Moab May 22 at 5:25
  • If "HibernatedEnabled" is 0, set it to 1. – Moab May 22 at 5:26
  • This does indeed add Hibernate to the shutdown options, but the Sleep option above is still grayed out. – jbbarnes77 May 22 at 16:16
  1. Launch Local Group Policy Editor (gpedit.msc)
  2. Navigate to Computer Configuration > Administrative Templates > System > Power Management > Sleep Settings.
  3. Check if any policy is enabled or disabled. Change it back to not configured.

  • @Moab Did you try it? It is the only policy where sleep can be disabled... – Bhavya Gupta May 23 at 5:03
  • Yes, I did try it. All of them were at default. So I set en/disable appropriately and restarted. However, the "Sleep" option still wasn't listed. Enabling hibernation with powercfg instantly restores "Hibernate" to the menu, even without a reboot. – jbbarnes77 May 23 at 6:04
