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 10/11. However, this is usually the case when you are using an Always-On/Always-Connected (AOAC) platform.
Pro Tip: Run a dedicated PC optimization tool to get rid of incorrect settings, junk files, harmful apps, and security threats that can cause system issues or slow performance.
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.
What To Do If Power Management Tab Is Missing in Device Manager?
If your Power Management tab is missing from Device Manager and you want to get it back, there are several things you can do. But before you do so, make sure you optimise your computer using Outbyte PC Repair and backup your files in case something went wrong. This is highly recommended when you are going to edit the Registry.
Solution #1: Modify the power management.
You can modify the power management for the hardware devices on your computer to get back the Power Management tab on Device Manager. To do this:
- Press the Windows + R buttons. This should open the Run dialog.
- After that, type in main.cpl and click on OK.
- Once the Mouse Properties appear, go to the Hardware tab.
- Click on Properties to modify it.
- Now, click on the General section.
- Then click on the Change settings.
- Next, locate the Power Management tab. Click on it.
- Uncheck the Allow this device to wake the computer option.
- Click on OK to save the changes on your computer.
- Once you are done with the mouse settings, you have to do the same with the keyboard settings.
- Right-click on the Windows key and click on Device Manager.
- After that, expand the Keyboards device.
- Right-click on the keyboard driver and click on Properties.
- Go to the Power Management tab. Click on it.
- Uncheck the Allow this device to wake the computer option.
- Do not forget to click on OK to save this change.
Put your system in sleep mode and check out if the fix has worked out for you.
Solution #2: Enable USB Wake support.
You can also try enabling the USB Wake support option on your computer by following the steps below:
- Turn off your computer.
- Turn it on again.
- While your system boots up, simply press the Delete key from your keyboard to open the bios setup on your computer. The actual key to access the BIOS settings may be different for your system. This key varies from manufacturer to manufacturer. Here are some of the keys you can try: Esc, F1, F2, F10, F11, F12 or Delete
- When the BIOS setup opens up, go to the Advanced settings.
- Check if there are any options called USB wake support.
- Click on the drop-down and set it to Enabled.
- Save your settings by pressing F10.
- Select Yes to finally save and exit the bios settings on your computer.
Let your Windows 10/11 system boot up normally and see if the Power Management tab has been restored.
Solution #3: Edit the Registry.
Take note that editing the registry might cause damage to your computer if not done correctly, so you need to closely follow the instructions below:
- 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.
- Navigate to the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
- Now right-click on Power and select New > DWORD (32-bit) Value.
- Name it as CsEnabled. By default, it comes with 0 as the Value data, and you do not have to change it.
- Restart your computer and open the device’s Properties. You should 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.
The Power Management tab is useful for managing and customizing the power settings on your computer. Although there are other options that allow you to tweak your power settings, this tab makes all these settings accessible in one place so you don’t have to go around and open other windows. If you can’t find the Power Management tab under Device Manager, the above solutions should help you get it back in no time.
