    Any way to know why my laptop reboots (while sleeping)


    A lot of times, when I come back to my laptop, I find that it has restarted. I'm using a Dell XPS 15 with Windows 10 Build 18363.

    How can I troubleshoot why it happened?

  2. Audio device unrecognised after waking from sleep


    From time to time I wake my laptop from sleep and find that the audio driver (Conexant Venice) is no longer loaded. The audio hardware is listed in the Device Manager as just "base system device" (or two base system devices, to be precise). Rebooting fixes the problem each time, but it takes a while. Is there a quicker way to make the audio work again than rebooting? I've tried obvious steps like running the troubleshooter and disabling and then re-enabling the devices.

  3. Laptop will not sleep or hibernate

    Sleep mode is a great way of keeping your PC ready to go at a moment’s notice without wasting power. If it stops working, we suggest that you run the Power Troubleshooter. See steps below:

    • Type Troubleshooting on the search box. Click on the
      Troubleshooting
      from the search results.
    • On the left panel, click on View all and select Power.
    • Follow the on-screen instructions.

    You can also update all the drivers
    of your PC.

    Let us know if you have any other questions.

    Waking PC up from sleep mode causes a reboot

    Problem:





    I have a small group of Dell Latitude E7470 (Bios Version 1.11.3) laptops that have and sleep mode issue.





    When a user closes the top cover of the laptop and puts the machine to sleep all appears normal and the power light begins to pulse. Then, when the user opens the top cover to begin using the laptop
    once again the laptop fails to wake up from sleep mode and restarts causing the user to log into the laptop each time. The laptop behaves this way regardless of the way it entered sleep mode, e.g. via the power button or from the start menu.





    • The laptop power settings are defined by group policy.
    • All of the affected laptops are running Windows 10 1809 Enterprise.
    • The issue does not appear to be a user problem as the issue occurs whether or not a user signs into the laptop.
    • The bios was updated prior to imaging the laptop in the spring of 2017. v1.11.3




    Troubleshooting:





    The following steps have had limited success.





    • Bluetooth on/off. Sometimes if we leave the Bluetooth off the issue goes away, but not always.
    • Changing what closing top cover does, e.g. change the setting of the top cover to do nothing when closed and then return the setting back to sleep when the top cover closes.
    • Swapping SSD from one computer to another identical make/model computer and then back. In this step, we move the affected SSD to another laptop and boot the computer. then log in and test sleep mode.
      at this point, the issue is not present. Then, we place the SSD back into it's the original laptop, so far, this has been successful, however, we are still not confident this is a long term fix and we would like to understand why this step would have the
      effect that it does.
