Windows 7: ASUS laptop restarts instead of shutting down

My new ASUS laptop will not shut down. I saw a thread a couple of days ago where a Richc46 said to try disconnecting the internet connection and then trying to shut down and if that worked he knew how to fix it. However, the thread ended there. I tried this and disconnecting the internet connection worked. Can someone please tell me how to fix this problem. I think Richc46 said it was something to do with the device manager, but I may be remembering that wrong. All of the other shut down menu options work (hibernate, sleep, restart, etc), it just won't shut down and restarts instead.

UPDATE: I had tried the disconnection of the internet and it worked and successfully shut down ONCE. I just tried it again and it is restarting like it had been, so it's not as easy as just stopping the internet connection.

Hello amigraarm and welcome to Seven Forums.

You may find there are several possible reasons why a computer restarts after shutdown. I'd suggest going through these Microsoft forum threads. Before attempting any of the suggested fixes it would be a good idea to create a restore point (or even better, a system image) just in case things get worse than they are.

Please post back if any of this helped or not.

If it's new then you have a full hardware and tech support warranty for one year. I'd call them to fix or replace it, or take it back to the store for another model.

following the steps and using the installer in the blue link to get it perfect. If it solves the issue then we can help you remove the bloated factory preinstall to use the test install permanently.
