[Windows 11] PC turns itself back on immediately after shutdown - All standard fixes already tried

Hi everyone,

I'm dealing with an infuriating issue on my Dell Latitude E7470 running Windows 11. Immediately after shutting down, the computer stays off for a few seconds/minutes and then turns itself back on.

I can't isolate the cause. I've already gone through all the standard troubleshooting steps (both OS and BIOS level) with no success. Here is the detailed list of what I have already tried, so we can rule out the most common causes:

  1. Windows Power Settings:

Disabled "Fast Startup" in Power Options.

Set the power button and lid close actions to "Shut down" (Sleep and Hibernate disabled).

Disabled "Wake Timers" for both battery and plugged-in states in Advanced Power Settings.

Unchecked "Allow scheduled maintenance to wake up my computer" in Security and Maintenance.

  1. Command Prompt & System:

Completely disabled hibernation via powercfg -h off.

Ran powercfg /lastwake: it shows no active wake devices (nothing is plugged into the USB ports either).

Disabled "Automatically restart" upon system failure (sysdm.cpl > Advanced > Startup and Recovery) to rule out a BSOD during shutdown. No blue screen appears.

  1. Network & Peripherals:

In Device Manager, unchecked "Allow this device to wake the computer" for all network adapters (LAN and Wi-Fi) and mice/keyboards.

  1. Hardware & BIOS/UEFI (Dell Latitude E7470):

Accessed BIOS > Power Management and disabled: Wake on AC, Auto On Time, Wake on LAN/WLAN, USB Wake Support, and Power on Lid Open.

Performed a Hard Reset by holding the power button for 30 seconds while unplugged from AC power.

Deep Shutdown Test: Forced a full shutdown bypassing the OS by holding SHIFT while clicking "Shut down". The PC shut down completely but still turned itself back on.

AC Adapter Isolation Test: Shut down the PC and, the exact second the screen went black, physically unplugged the AC adapter. The PC still turned itself back on using only battery power.

It seems a low-level trigger is bypassing all software/hardware blocks. Is there any hidden registry key in Windows 11, or a specific Event Viewer log I can check to track down the exact process triggering the boot? Has anyone experienced similar anomalies with Dell power management drivers and Windows 11?

Thanks in advance for any help.

    Hello

    There is a good chance this has nothing to do with software/Windows/Microsoft products.

    But just to be thorough, can you launch Powershell admin mode, and copy paste this command, and share a screenshot of the results please,. 

    Get-WinEvent -FilterHashtable @{
    LogName='System'
    Id=12,13,41,1074,6005,6008,6009
} -MaxEvents 30 |

    Given the steps already completed, the most useful next check is Event Viewer immediately after the unwanted power-on.

    1. Open Event Viewer → Windows Logs → System.
    2. Look at entries around the exact shutdown/restart time for these event IDs:
      • 41 (Kernel-Power)
      • 6008
      • 1001
      • 1074
    3. If 1074 appears, check the recorded Shutdown Type and the process that initiated it.

    A key distinction from the available guidance:

    • If the system is coming back because of a forced power-button action, Windows can log Event ID 41 with a nonzero PowerButtonTimestamp.
    • A dirty shutdown or forced power-off can also be associated with Event ID 41.

    Based on the documented behavior, an immediate power-on after shutdown is not explained by standard Windows wake behavior if the machine is truly reaching S5 soft off. Wake-on-LAN is supported from S3 sleep or S4 hibernate, but not from fast startup or S5 soft off shutdown states. Some BIOS implementations may still arm the NIC for wake independently of Windows, but Windows is not involved in that process.

    For Windows-side troubleshooting that is still supported by the available guidance:

    1. Check Device Manager for any device with an exclamation mark and update, disable, or uninstall the affected device.
    2. Install the latest Windows 11 updates from Start > Settings > Windows Update.
    3. If the issue continues, start in Safe Mode and test shutdown behavior there.
    4. If shutdown/restart problems persist, use Recovery options in Windows 11 or a system restore point.

    If Event Viewer shows BugcheckCode = 0, no minidump, and no BSOD, the documented Q&A guidance points more toward a hardware or firmware-level reset/power event below the OS than a Windows process or hidden registry setting.
