This issue affects users who experience their computer restarting unexpectedly when shutting down, with the only reliable method being to immediately turn off the monitors or use a shutdown command. This can be frustrating for those trying to shut down their computers without interruption.

The problem's root cause is not yet fully understood but may be related to the BIOS settings or a specific interaction between hardware components and Windows 10. A reinstall of the operating system did not resolve the issue, suggesting that it might be a more complex problem requiring further troubleshooting.

⚠️ Common Causes

  • One possible reason for this behavior is an incorrect or out-of-date BIOS setting related to monitor control or power management. When the computer is shut down and the monitors are not turned off immediately, Windows may attempt to send a signal to the monitors to turn them off, which can cause the system to restart if it fails. This could be due to a faulty monitor connection, a misconfigured BIOS setting, or an issue with the graphics card.
  • Another potential explanation is that there's a conflict between the Windows shutdown process and the power management settings of the computer's hardware components. In some cases, the computer may attempt to shut down other devices connected via USB or other interfaces while shutting down the main system, which can cause it to restart if these devices are not properly disconnected.

🔧 Proven Troubleshooting Steps

Disable Monitor Synchronization in BIOS

  1. Step 1: Enter the BIOS setup by pressing the designated key (usually F2, F12, or Del) during boot-up. Navigate to the 'Advanced' or 'Monitor' settings section.
  2. Step 2: Look for an option related to monitor synchronization or power management and set it to 'Disable' or 'Off'. Save the changes and exit the BIOS setup.
  3. Step 3: Restart the computer and shut down normally without turning off the monitors. Check if the issue persists.

Use a Shutdown Command with Monitor Turn-Off

  1. Step 1: Open the Command Prompt as an administrator. You can do this by searching for 'cmd' in the Start menu, right-clicking on it, and selecting 'Run as administrator'.
  2. Step 2: Type the command `shutdown /s /f /t 1` (or a shorter version like `shutdown /s /f`) and press Enter. This will force Windows to shut down immediately.
  3. Step 3: While the shutdown process is running, quickly turn off all monitors. Check if the computer does not restart after shutting down.

✨ Wrapping Up

To resolve this issue, try disabling monitor synchronization in the BIOS settings or using a shutdown command with monitor turn-off. If neither method resolves the problem, further troubleshooting may be necessary to identify and address any underlying hardware or software conflicts.
