Windows 10 goes to sleep ignoring the settings

sleepwindows 10

My Lenovo laptop's settings:

  • is plugged in
  • no screensaver
  • "never" go to sleep/hybernate set to all settings in advanced power options

When music is playing or watching video everything works fine.
But when nothing is happening pc goes to sleep after ~1 min.
Not sure, but it doesn't happen right after restart, only after I begin working.
Here is the system log for sleep event:

  • System

How can I solve it?

Best Answer

It is the System unattended sleep timeout setting.

By default it is set to 120 seconds and is hidden.

Setting the registry data Attributes under key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0 to value 2 (or 0) makes the option appear in the advanced power settings, under Sleep and can be set to something normal.
