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

    We need to run a battery report just to check if the battery itself is having a hardware issue. To do this, kindly follow the steps below:

     

    Search for Command Prompt or Terminal> right-click and select “Run as administrator”

    Copy, paste, and enter the command:

    powercfg /batteryreport /output "C:\battery_report.html

    Then go to: Drive C: or C:\ and look for “battery_report”

    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

    If your laptop does not turn on without being plugged into the charger, it may indicate a problem with the battery or the charging system. Here are a few steps you can take to troubleshoot and potentially fix the issue:

    1. Check Battery Health: Ensure that the battery is functioning properly. If the battery is old or has degraded, it may not hold a charge effectively.
    2. Power Cycle the Laptop: Disconnect the charger, remove the battery (if possible), and hold the power button for about 15 seconds. Then, reconnect the battery and charger and try to power on the laptop again.
    3. Check Charger and Connections: Make sure the charger is working correctly and that the connections are secure. Sometimes, a faulty charger can cause these issues.
    4. Battery Calibration: If the battery is recognized as fully charged but the laptop won’t turn on without the charger, you may need to calibrate the battery. This can involve charging it to 100%, then letting it discharge completely before charging it back to full.
    5. Update Drivers: Ensure that your battery drivers and firmware are up to date. Sometimes, outdated drivers can cause charging issues.
    6. Run Diagnostics: If your laptop has built-in diagnostics (like the Surface Diagnostic Toolkit), run it to check for any hardware issues.

    If these steps do not resolve the issue, the battery may need to be replaced, especially if it is not holding a charge despite showing 100%.
