  1. Unexpected Laptop Shutdowns

    My laptopis getting unexpected shutdowns, totally out of the blue when left idle. I have ran HP Hardware Diagnostics, Memory Diagnostics, Monitored CPU Temperatures, Updated Windows, Created Custom Power Plans but unable to pinpoint what is causing the shut downs. On checking the event viewer I found the following Critical Errors just about the time it shuts down.

    Event 142, Kernel Power: The system has rebooted without cleanly shutting down first. The error is caused because the system stopped responding and the hardware watchdog triggered a system reset.
    Event 41, Kernel Power: The system has rebooted without cleanly shutting down first. The error could be caused if the system stopped responding, crashed or lost power unexpectedly.

    Also, in the Error List, I can also find Event 13, HAL: The system watchdog time was triggered, happening just at the same time.

    Here's my Administrative Log: Administrative Log Please let me know if you need any more information to help me troubleshoot.

  2. Unexpected Shutdown


    Please see response to your questions below

    • Did you make any changes on the computer prior to this issue?
    No changes other than about a month ago reinstalling W10.

    • What troubleshooting steps have you done so far?
    Other than checking updates have successfully installed, none as not sure approach to take.

    • What was the exact error code/message you have received?
    No error code or message received. On the first occasion I was looking at outlook and without any warning the PC shutdown. It was almost as if it was a desktop (it is a laptop) and the power stopped. The laptop was plugged into the mains and in addition
    the battery had a full a full charge.

    On restarting the laptop no error message came up and I only noted a small difference in boot up, that for a short period a blue screen was displayed (not normally seen on boot up) and then the start screen appeared for me to log in.

    As mentioned previously the only reference to this is from the log which in the summary states that there was an unexpected shutdown.

    PC is Suffering Unexpected Shutdowns

    Most important detail to me would be whether these shutdowns are sudden, in which case it's likely a short or PSU issue (capacitor aging maybe?) or graceful windows style shutdowns, which suggests software interference.

    It could also be overheating components if it's a sudden shutdown. What are your thermals like?
