Repeated sudden shutdown on battery – Kernel-Power Event ID 41 despite firmware updates

Dear Support Team,

I am writing to report a serious and recurring issue with my laptop that I have been unable to resolve despite extensive troubleshooting.

Problem description: My laptop shuts down suddenly without any warning when running on battery power (even at 50–70% charge). The screen goes black instantly with no shutdown animation or error message. The system only powers back on when I press the power button again.

Observed behavior:

  • The issue occurs only when the charger is unplugged

Battery health is 100% (confirmed via battery report)

No overheating is observed

Windows Event Viewer consistently logs Kernel-Power Event ID 41, indicating an unexpected power loss

No blue screen or Windows crash is recorded

Troubleshooting already performed:

Updated BIOS, Embedded Controller (EC), and Intel Management Engine firmware (successfully)

Adjusted Windows power settings (CPU throttling, PCI Express power management, battery thresholds)

Verified battery condition and capacity (new laptop, battery is healthy)

Checked Device Manager for driver rollback/disable options (not available due to firmware control)

Issue still occurs after all updates and configuration changes

Impact: This issue makes the system unreliable and unusable on battery power, which defeats the purpose of a portable device.

Request: I would like your assistance to:

Identify the root cause of this sudden power loss on battery (firmware, driver, or hardware-level issue)

Provide a permanent solution or official guidance

Confirm whether this behavior qualifies for repair or replacement if it is a known hardware or firmware defect

Please let me know what additional logs, tests, or information you require from my side. I am available to cooperate fully to resolve this issue.

Thank you for your time and support.

Kind regards, BasitDear Support Team,

    Open File Explorer.

    Go to C:\Windows\LiveKernelReports\WATCHDOG

    In that folder or any sub-folder in there, is there any watchdog dump (dmp) files created?

    If there are, copy any available dump files onto your Desktop, then zip those up.

    Upload the zip file to the Cloud (OneDrive... etc.), then choose to share those and get a share link.

    Then post the link here to the zip file, so I can take a look for you.

    The issue you're experiencing with your laptop shutting down unexpectedly while on battery power, despite the battery showing 100% health, can be quite frustrating. Based on the details you've provided and the context of Kernel-Power Event ID 41, here are some potential causes and troubleshooting steps:

    1. Power Supply Issues: Even if the battery health is good, there might be an issue with the power supply circuit or the battery management system that causes the laptop to shut down unexpectedly. This can happen if the power supply is underpowered or faulty.
    2. Firmware and Driver Updates: Since you've already updated the BIOS and other firmware components, ensure that all drivers, especially those related to power management and chipset, are also up to date. Sometimes, specific driver updates can resolve power-related issues.
    3. Power Settings Configuration: You mentioned adjusting Windows power settings. Ensure that the settings for sleep and hibernation are configured correctly, as aggressive power-saving settings can sometimes lead to unexpected shutdowns.
    4. Overheating: Although you’ve stated that no overheating is observed, it’s worth double-checking the internal temperatures of the CPU and GPU when the laptop is under load. If thermal throttling occurs, it might lead to sudden shutdowns.
    5. Hardware Malfunctions: Since the problem persists despite extensive troubleshooting, it could indicate a hardware malfunction. This could involve the motherboard, power circuitry, or even the battery itself, despite its reported health.
    6. Testing with Different Load Conditions: Try running the laptop under different load conditions (e.g., with minimal applications open) to see if the shutdowns still occur. This can help identify if the issue is related to specific software or hardware loads.
    7. Event ID 46: If you encounter Event ID 46 in the logs, it indicates a failure in crash dump initialization, which could suggest issues with the pagefile configuration or the system's ability to write dump files. This could further complicate diagnosing the root cause.

    Given the circumstances, if the issue continues after following these suggestions, it may be advisable to contact the manufacturer for further assistance, as it could qualify for repair or replacement if it is a known hardware defect.
