Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

Just to confirm, do you encounter a Blue Screen error with the error message failed WIN32k.sys? if yes, can you please check if you have minidump files on the PC so I can further examine the root cause of the issue?

 

Press Windows key + E (To open File Explorer)

 

Click "This PC" > then follow the file path:

 

C:\Windows\Minidump

 

Copy the Minidump files and save them to another location, like the Desktop or Documents.

 

Then please upload it to Cloud storage like OneDrive or any cloud storage you are using, and please share the shareable link here.

To upload and share the link using OneDrive:

Go to this link: https://onedrive.live.com/, then upload the file.

Then provide the shareable link by following the steps from this link: https://support.microsoft.com/en-us/office/share-onedrive-files-and-folders-9fcc2f7d-de0c-4cec-93b0-a82024800c07

    Hi Edd, thank you for that information. The CPU test is all good. However, if there is a charging error, kindly follow the steps below:

    Method 1. Reinstall Battery Drivers (Skip this process if you have already tried to uninstall all drivers under the batteries)

     

    -Press the Windows key + X

    -Go to Device Manager

    -Expand the Batteries

    -Right-click, then uninstall all drivers there.

    -Restart the PC and check it again

     

    Method 2. Restore default power options

    -Press Windows key + R, then type:

    powercfg -restoredefaultschemes

    -Restart the PC and check.

     

    Method 3. Run power, Troubleshooter

    • Press Windows key + R then type:

    msdt.exe /id PowerDiagnostic

    • Click OK, then follow the prompts to run the power troubleshooter.

    -Restart the device after.

     

    Note: If the issue persists, I suggest contacting a local technician to physically check the device for any hardware-related issues.
