I am really happy running Ubuntu 13.04 but unfortunately i am unable to shut down my laptop at night? When i go to the gear wheel icon in the top right-hand corner and select shut down it does exactly that but within a few seconds starts to reboot? I was fortunate in that i had Puppy Linux Slacko installed on a USB stick and now in order to shut down my laptop at night i must reboot the machine into Puppy Linux Slacko just to shut down.

I know very little about computers or operating systems but there must (in my opinion) be something wrong with Ubuntu 13.04 for this to happen?

Despite the problem with shutting down the machine at night i'm will continue to use Ubuntu 13.04 because i think it is still the best OS around!
