Power Management tab missing in Device Manager on Windows 11/10

If you are trying to change something related to the deνіce’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.

Precaution: It is recommended to backup all Registry files or create a System Restore point to be on the safe side.

Power Management tab is missing in Device Manager

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

1. Search for registry editor in the Taskbar search box.
2. Click on Registry Editor in the search result.
3. Click the Yes button.
4. Navigate to Power in HKLM key.
5. Right-click on it > New > DWORD (32-bit) Value.
6. Name it as CsEnabled.
7. Restart your computer.

To get started, search for “registry editor” in the Taskbar search box and click on the Registry Editor in the search result. It will open the UAC prompt. Click the Yes button to open Registry Editor on your computer. After opening it, navigate to the following path-

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power

Now right-click on Power and select New > DWORD (32-bit) Value.

Following that, name it as CsEnabled.

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

If you are done with the above step, restart your computer and open the device’s Properties. Now you will find the Power Management tab.

In case you want to hide this tab for security or any other reason, navigate to the same path, double-click on CsEnabled, and set the Value data as 1.

Then, click the OK button to save the change. As usual, restart your PC to get the difference.

If this does not help, you could run the Power Troubleshooter as well as the Network Troubleshooters and see if that helps.

Where is the Power Management tab in Device Manager?

Open Device Manager > Expand Network adapters > Right-click on the Network card > Select Properties. You will see the Power Management tab there.

Hope this guide helps.
