The Power Management tab may be missing on the later versions of Windows 10 and 11. To bring it back, go to the Registry Editor (as shown in section 6), and paste this path: "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Power." Right-click on the white space on the right, and select "New -> DWORD (32-bit) Value." Name it "PlatformAoAcOverride." Double-click the value, and ensure that the "Value data" field is set to “0.” Finally, click "OK." Restart your computer to apply the changes.
