FIX Missing Power Management Tab in Device Manager (10/11)

Is the Power Management tab missing in Device Manager? It is one of the most common problems in modern Windows systems. Here’s how to deal with it.

In the Device Manager, most devices have a dedicated power management tab that allows you to configure whether the computer can turn off the device to save power or if the device can wake the computer. For example, when you put your computer to sleep, moving the mouse or pressing a key on your keyboard can wake up your computer. However, if the Power Management tab is missing in the Device Manager, you cannot easily control this behavior.

In this guide, I will let you know why the power management tab is missing and what you can do to fix the problems caused by this. Let’s get started.

Before You Start

• On older versions (pre Windows 10), creating a registry key called “CsEnabled” generally fixed the problem. But on Windows 10 and Windows 11, Microsoft has removed this feature, and it no longer works.

Missing Power Management Tab in Device Manager

On Windows 10 and Windows 11, if the Power Management tab is missing, there are three main reasons. They are as follows:

• Your computer is using Modern Standby (S0) mode instead of the older modes like S3.
• Your device driver doesn’t support power commands.

In both cases, you need to follow the workaround shown below. Though it doesn’t restore functionality, it eliminates the annoyance of not being able to configure power commands.

Check If Your Computer is Using Modern Standby (S0) Mode

Unlike older, more popular standby modes, such as S3, which puts your computer in deep sleep and suspends almost all activity, Modern Standby (S0) keeps your computer or laptop ON but in a very low-power state. This not only allows the device to wake up instantly but also lets it maintain a network connection to receive notifications, check email, sync data, and more.

Since Windows takes full control of how your device behaves when you put it to sleep, the Power Management tab is no longer required, and it is automatically hidden. That’s the reason why you don’t see the Power Management tab when your computer uses Modern Standby.

To check if your computer is using Modern Standby (S0), follow these steps:

1. Open the Start menu.
2. Search for “Command Prompt” and click “Open“.
3. Type “powercfg /a” and press “Enter“.
4. If it says Standby (S0) under the “following sleep states are available”, then your computer is using S0 Modern Standby.

Important note: Do NOT forcefully switch to S3 mode, especially if the above command says “The system firmware does not support this standby state”. This is unsafe and may cause overheating and damage hardware.

The Device Driver Doesn’t Support Power Management Features

If you see the Power Management tab for other devices but not for a specific device, it might be because that device doesn’t support this feature.

To make sure your driver isn’t at fault, I recommend reinstalling the driver downloaded from the manufacturer’s website. Do NOT use the generic Microsoft driver as it often lacks the advanced power management features.

If the Power Management tab is still missing even after installing the driver recommended by the device manufacturer, the device doesn’t support advanced power features.

In both cases, follow the workaround shown below. Even without the Power Management tab, you can prevent devices from waking your system at random.

Safe Workaround to Fix Missing Power Management Tab

Even if the Power Management tab is missing, we can use the command line to find which devices are waking up your computer and stop them. Here’s how:

1. Open the Start menu.
2. Search for “Command Prompt“.
3. Select the “Run as administrator” option.
4. Run the “powercfg -devicequery wake_armed” command to list the devices that can wake your computer.
5. Run the powercfg -devicedisablewake "DeviceName" command to stop a specific device from waking the computer. Rename “DeviceName” with the exact name of the device you get from the first command.

With that, that specific drive is disabled from waking your computer. If you have more devices, run the second command on each device individually.
