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.
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.
