XPS 15 (L501X) Won't shut down or restart

This question is not answered

The issue is that once Windows shuts down, the machine itself will stay powered up, and won't shut down completely, or won't restart when I select restart, and I need to hit the power button in order to get the machine to power down.  When selecting shut down, I need to hold the power button down for a few seconds before the machine will power down, and when I select restart, touching power instantly powers down the machine.

I've looked as some other topics, seeing to unplug all USB peripherals, and I've done so, yet it still happens. It's not a major issue to me, but it would be nice to have things work properly. Any help would be appreciated.

  • Hi Guinness79,

    Ensure that the wake timers are disabled. Follow the instructions below to disable the same.

    1. Left Click on the power icon at the bottom right of your start bar

    2. Click on "More Power Options" (or just search for "power options" on your start bar)

    3. Click on "Change plan settings" on either Balanced or Power Saver (depending on which one you use)

    4. Click on "Change advanced power settings"

    5. Once your Power options panel opens, scroll down and select “Sleep"

    6. Click on "Allow Wake Timers" and then click on "Enable" and scroll down to select it as "Disable"

    Also Load the Bios defaults and if the issue persists flash the latest Bios from the below link.

  • Nothing changes after that. I had already set the power options to disable as you had mentioned. Loading the BIOS defaults didn't change anything, and the BIOS are already updated and the utility won't flash them when it's already up to date.

    Any other ideas?

  • Hi Guinness79,

    This could be a motherboard issue. You could also run a diagnostics to check for hardware issues.

    Kindly find the steps below to perform the Hardware diagnostics.

    Turn the computer off >restart the computer , At the Dell logo screen, start tapping the F12 key a few times until you see the ‘One Time Boot Menu’ appear. At the one time boot menu, press the down arrow key to highlight ‘Diagnostic’, and then press Enter to begin the PSA diagnostics. If the test fails, please make a note of any error codes listed. You can also refer to the link below.

  • I am experiencing the same problem, I have updated the BIOS version to A8,installed latest chipset drivers and even tried the diagnostic as you have suggested and it completed without any errors.As a last resort I reverted to the old version of BIOS (A04) after reverting to the old version of BIOS the laptop restarted correctly but the consequent attempts to restart failed and the problem still persists. Any help is appreciated

  • as per your suggestion when i have try to shutdown in safe mode windows stops responding and hangs until I forcefully shutdown by pressing the power button for some time,and when i try to restart in safe mode it simply shuts down.

  • Hi skidibidi,

    I would suggest you to run hardware diagnostics on the system for hardware functionality, by following the steps below:

    • Reboot and press F12 to enter the Boot Menu
    • When the boot device list appears, highlight Diagnostics and press Enter
    • The computer begins to run the Pre-boot System Assessment, a series of embedded diagnostics that perform initial testing on your system board, keyboard, hard drive, and display
    • In case any hardware component is bad, you will get a corresponding error

    Please create another user account as mentioned above and share the results.

    Keep me posted with the information. I will be glad to assist further.

    Thanks & Regards

  • I have already run the PSA diagnostic and it completed without any errors or warnings,Please let me know if you have any other suggestions

  • Hi skidibidi,

    It seems the issue is with the operating system. You may restore the system back to factory settings. Please refer to the link: http://dell.to/1980CrK.

    * Note: This step leads to complete data loss including pictures, music files, videos, documents and applications. Please disconnect any external peripherals as well.
