PC Repair Windows
Device Manager

The power management on your computer manages which devices will receive power in specified conditions (like Sleep or Hibernation mode). It also controls which hardware can wake the computer up from sleep. If you can’t find the power management device on your computer, don’t worry.

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 several methods to get it back.

Why is the Power Management Tab Missing in Device Manager

By default, the Power Management tab should be accessible when you open Device Manager. There is no specific reason why the Power Management tab is missing in Device Manager of Windows 10. However, this is usually the case when you are using an Always-On/Always-Connected (AOAC) platform.

In this scenario, you will notice that the Power Management tab is no longer available within the advanced driver properties. This behavior is by design. With AOAC platforms, Windows needs to systematically manage the adapter’s power state to achieve Connected Standby. Thus, the Power Management tab is not provided for the user to uncheck the Allow the computer to turn off this device to save power option. On non-AOAC platforms, the Power Management tab is retained.

But sometimes the error can be caused by a faulty update that has broken the Power settings of your computer. If you’ve recently installed an update when you encountered this issue, then that’s probably the culprit behind this error.
