No shut down always reboots

I just replaced the screen in a Dell laptop. Everything seems fine with one exception. When I click shutdown, the laptop shuts down and then immediately boots up. The properties of the start button is set to shut down. I also retraced my steps of installing the screen and do not see anything like crimped wires or loose connections. Any ideas?


I also set it to not auto reboot to see if I had a code. No code. Still reboots.

Try opening an elevated command prompt and type "shutdown -s -t 00" (without quotes) and see if a forced system shutdown still reboots.
 
Did you check the BIOS to verify that reboot on power failure was not set? I'm not sure if that's what you meant in your last sentence or not.
 
I actually found it. The issue was the wireless network connection. I disabled it and the laptop shut down properly. Enabled it and it shut down then rebooted. Loaded the driver from the dell site for wireless and all is well. Don't know what I did that caused it other than you have to disconnect the antenna when you replace the screen.
 
Yea...well...some BIOSES have an option to wake computer up if network connection is present...so if your wireless connection was on then the computer's BIOS immediately detected it and disabled the computer from shutting down.
But that is rarely the problem and it would be kinda hard that it affects the Windows driver since they all shut down during the shutdown process.
But it's possible since I saw cases like these...,but EXTREMELY rarely lol.

My super old BIOS even have those kind of options to wake the computer up if you do ANYTHING to it...even if you just MOVE THE MOUSE the computer would IMMEDIATELY wake up lol.
