If the display of your Windows 10 computer turns on all of a sudden no matter how put it to sleep over and over again, it always wakes up, read on as this post will guide you in resolving this peculiar issue.
In case you don’t know, the Windows 10 computer Sleep state is made in such a way that if it’s really important, it wakes up. You may have configured this kind of behavior or there could be some hardware component that’s interrupting its Sleep state. Thus, this post will give you some troubleshooting tips to fix the Sleep state issue caused by the Legacy Kernel Caller. The Legacy Kernel Caller points to the external hardware that’s causing your Windows 10 to wake up even when it’s in a Sleep state.
Step 1: Find out what’s keeping your computer from going to sleep.
To figure out what really is keeping your computer from going to sleep, you can execute the “powercfg –requests” command instead of checking the power configuration of your computer. This command will look for requests from applications and drivers that prevent the computer from turning off the display or from going to sleep.
To execute the command, simply open Command Prompt and type “powercfg –requests” and hit Enter. After that, you will see part of the result that looks like this:
“SYSTEM
[DRIVER] USB AUDIO DEVICE
An audio stream is currently in use
[DRIVER] Legacy Kernel Caller.”
Step 2: The next thing you have to do is remove all the external hardware connected to your computer.
In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used.
Step 3: Try using the request override option
The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.
Powercfg -requestsoverride Driver "Legacy Kernel Caller" System
Step 4: Check the streaming and media applications
You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services.
Step 5: Check the devices that can wake your computer
If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.
powercfg –devicequery wake_armed
After you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties
Step 6: Check the Sleep Advanced Settings
On the other hand, you could also run the Power Troubleshooter to resolve the Sleep state issue. This built-in troubleshooter will automatically fix any power-related issues in your computer.
