If you are trying to change something related to the device’s power management, but the Power Management tab is missing in Device Manager, here is what you will have to do. You can get back the Power Management tab in the device’s Properties after making a tiny change in the Registry Editor.
Where is the Power Management tab in Device Manager?
To access the Power Management tab for a device, first, open the Device Manager, and expand a device section (say Network adapters). After this, right-click on the selected device, and click on the Properties option. You will see the Power Management tab there.
What is the use of the Power Management tab in Device Manager?
The Power Management tab in Device Manager lets you set which devices are allowed to wake your computer and which devices can turn it off. You can find the Power Management tab for devices like Mouse, Bluetooth, Keyboard, etc. Also, do note that not all the devices support this Power Management tab.
Let’s assume that you want to charge your phone in Sleep Mode with the laptop lid closed. For that, you must uncheck the option saying Allow the computer to turn off this device to save power. This option appears in the Power Management tab when you go to the Properties of any device. Whether it is a network adapter or USB controller, you can find the same tab at the mentioned location. However, if it is not there and you must need it, you can use Registry Editor to get it back.
Precaution: It is recommended to backup all Registry files or create a System Restore point to be on the safe side.

To fix the missing Power Management tab in Device Manager, follow these steps-

Following that, name it as CsEnabled.
By default, it comes with 0 as the Value data, and you do not have to change it.
