How to Fix Missing Power Management in Device Manager

If you cannot see the Power Management tab in Windows 10 Device Manager, you can fix the problem using the steps below:

Open Registry Editor. I suggest you take a Registry backup before proceeding.

Go to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Power.

Right-click the empty area of the right pane. Select New > Dword (32-bit) Value.

Enter CsEnabled as the name, then press Enter.

Restart your computer.

That’s it.

Note: If you want to hide the Power Management tab, double-click CsEnabled, change the value from 0 to 1, and click OK. Restart your PC.
