Solution 8: Use the Registry Editor

If you are still having the issue, then you can use some Registry edits to sort out the system’s wake up issue.

Warning: Proceed at your own risk as editing your system’s registry requires a certain level of expertise and if done wrong, you may cause everlasting damage to your PC/data.

Before moving on, make sure to create a backup of the system’s registry. Then launch the Registry Editor as administrator and check if the following registry edits resolve the system’s wake up issue.

Open Registry Editor as Administrator

Set the CsEnabled value to Zero

  1. Navigate to the following path:
    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
  2. Now, in the right pane, right-click in the white area and select New > DWORD (32-bit value).
    Create a New Dword (32-bit) Value of CsEnabled
  3. Then name the new entry as CsEnabled and set its value to 0.
    Set the Value of CsEnabled to Zero
  4. Then exit the editor and check if the system is clear of the wake-up issue.

Create the PlatformAoAcOverride Registry Key

    Open Command Prompt as Administrator
  2. Now execute the following:
    reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0
    Add the PlatformAoAcOverride Key to the Registry
  3. Now reboot your PC and check if the wake-up issue is resolved (you may have to use the S3 power state).

Solution 9: Disable the Scheduled Tasks

The issue may arise if a scheduled task is triggering the wake up of your PC. In this context, disabling the scheduled task (or its ability to wake up your PC) may solve the problem.

  1. Launch an elevated Command Prompt and execute the following (one by one):
    powercfg -lastwake
    
    powercfg /waketimers
    
    powercfg -devicequery wake_armed
  2. Now check which services/processes are triggering the issue. Then disable the service causing the issue or its ability to wake up your system.

Some users reported that the Update Orchestrator Service caused the issue. . For illustration, we will discuss the process for Update Orchestrator Service.

  1. Hit the Windows key and in the Windows Search box, type Task Scheduler. Then open the Task Scheduler.
    Open the Task Scheduler
  2. Now expand the Task Schedule Library > Microsoft > Windows and then, in the left pane, select Update Orchestrator.
    Expand Windows in the Task Scheduler Library
  3. Then, in the right pane, double-click on any of the tasks (e.g., Backup Scan) and navigate to the Conditions tab.
    Open the Backup Scan Task in the Task Scheduler
  4. Now uncheck the option of Wake the Computer to Run This Task and click on the OK button.
    Uncheck the Option of Wake the Computer to Run This Task for the Backup Scan
  5. Then repeat the same to any other task that can wake the computer and check if the system’s wake-up issue is resolved.

If the Wake the Computer to Run This Task is greyed out, then you may have to use a utility like PsTools, PsExec, or PowerRun that can enable a user to launch the Task Scheduler with System or TrustedInstaller privileges.

For illustration, we will discuss the process for the PsExec utility.

  1. Download the PsExec utility and then extract the contents of the downloaded file to a folder.
  2. Then launch an elevated Command Prompt and in the Command Prompt, navigate to the extracted folder by using the CD command.
  3. Now, execute the following in the Command Prompt:
    psexec.exe -i -s %SystemRoot%\system32\cmd.exe
  4. Then a new Command Prompt will be launched with the System account privileges. Now, in this new Command Prompt, execute the following to launch the Task Scheduler with the System account privileges:
    taskschd.msc
  5. Now repeat the process discussed above to disable the Wake the Computer option for the problematic task.

If that did not do the trick and you are tech-savvy, then you may create a scheduled task that executes a Command Prompt/PowerShell script/batch file to stop the task causing the issue.

Solution 10: Edit the System’s BIOS Settings

If none of the solutions has worked for you, then disabling the devices’ ability in the system’s BIOS to wake the PC may solve the problem. But keep in mind that the instructions mentioned below may differ a bit for you.

Warning: Advance at your own risk as editing the system’s BIOS requires a certain level of proficiency and if not done properly, you may brick your system and cause everlasting damage to your data.

  1. Boot your system into the system’s BIOS and navigate/expand the Power Management tab.
  2. Now open Auto on Time and disable it.
  3. Then open USB Wake Support and select Disabled.
    Disable USB Wake Support in the System’s BIOS
  4. Now apply the changes and open Wake on LAN/WLAN.
  5. Then select Disabled and apply your changes.
    Disable the Wake on LAN WLAN in the System’s BIOS
  6. Now boot your system in Windows and check if the wake-up issue is resolved.

If the issue is still there, then check if switching your monitor’s connection mode from HDMI to analog resolves the issue.
