Problem with system automatically turning back on 1-2 seconds after shutdown

gksdy2000

I bought Beelink SER7 about 4 months ago and used it well. But recently, Windows 11 started to automatically turn on after shutting down. I tried to fix it and ended up formatting and reinstalling Windows 11. It seemed okay at first, but after several tasks and several bootings, the same problem occurred again. Reinstalling Windows after that didn't help at all. In short, when I take certain actions, it seems to work for a while, but eventually the problem occurs again.
The same thing happens even if I update the BIOS, clear the CMOS, or remove and reconnect the part where the motherboard battery is connected.

Hello there,
1.Disable Fast Startup

In Control Panel, click the Power Options. Select the Choose what the power buttons do. Uncheck the “Turn on fast startup.”, click save changes.

2.Disable Automatic Restart

One of the best solutions to fix the sudden restart error is to switch off the Automatic Restart option. This solution is a temporary solution, though.

When you disable the automatic restart feature, it blocks the operating system from rebooting. However, if misused, that can harm system functions more than fix the issue, so proceed with the steps carefully on Windows 11.

Step 1: Open the Settings menu > System > About.

Step 2: Choose Related Links and tap on Advanced System Settings.

Step 3: Under the System Properties sections, go to Advanced > Startup and Recovery > Settings.

Step 4: Then, uncheck the Automatically restart choice under System Failure and press OK.

3.Reconfigure Network Adapter.

Right click start---device manager--network adapter--wireless/WiFi--properties--power management--Disable the option about allowing the device to access the computer system wakeup. Press OK.
