Laptop goes to sleep randomly

Soon after I upgraded to Windows 10, my laptop started to randomly go to sleep even if it hadn't been idle. Sometimes, it'll fall asleep within seconds of being started and sometimes it won't fall asleep for hours. But at some point, it falls asleep and it does so continually. I've tried literally everything I could find on the internet, including wiping my computer clean and starting over. So I'm completely lost now.

Hi Rebecca,

Welcome to the Forum.
  • Press windows key + S key together to give focus to your Search/Cortana field
  • In the Search/Cortana field type comm
  • In the search results locate and right-click on Command Prompt and select Run as administrator
  • When the User Account Control prompts you, click Yes
  • In the Administrator: Command Prompt console type or copy & paste the following command:
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0" /v Attributes /t REG_DWORD /d 2 /f

Press Enter key

Type exit then press Enter key to close the console.​
  • Now right-click on Taskbar and select Task Manager
  • Scroll to bottom of window, and right-click on Windows Explorer in the Processes column and select Restart. This will cause your monitor to darken/flash briefly as Explorer.exe restarts.
  • Close the Task Manager window
  • Press windows key + S key again to give focus to your Search/Cortana field
  • In the Search/Cortana field type Edit power plan then press Enter key
  • In the window that opens click the Change advanced power settings link
  • Expand the + Sleep
  • Expand the + System unattended sleep timeout then click on the 2 minutes and adjust to 30 minutes or whatever timeout you prefer to use.
  • Click Apply then click OK

At this point if you want you can adjust other settings to do with Power Plan if you wish. The above steps is an alternate method to using the Restore Default Settings button within the Power Plan when it has no affect.

Report back on any progress.​
