Windows device does not stay in sleep mode

Certain applications or OS changes can modify power options to keep a device in a highly ready sleep state, which can wake up Windows more easily.

The Window 10/11 Settings app will not show all the fine-grained adjustments made to a sleep setting, but Control Panel has options that might be able to reset them.

1. Open Start, type Control Panel, then open it.
    
2. Click System and Security, then Power Options. 
    
3. You will see your current power plan used. In this example, click Balanced (recommended) then click Change plan settings.
   
   
    
4. Click Restore default settings for this plan. Then Save.
   
   

When done restart your computer.

There are times where sleep settings cannot be adjusted back and remains in a highly ready sleep state. Consider shutting down Windows for such devices when placed in a confined space to not being used for a prolonged period.
