Yeah i had the reboot instead of shutdown Problem occasionaly too, activating S4/S5 in BIOS fixed it for me.

What do you mean by activating it? When option is it in the bios?

Thanks

Any way you can give me the dummy walkthrough on this? I still can't shutdown, it's auto rebooting on me too.

Enter BIOS with hitting F2 during boot-up, then go to the Power Tab and there is an option listed "Use S4/S5 Deep"
Activate it and reboot. That helped for me in the Stable 3.2.3 Frodo Build.
Now with Gotham i got a new problem, i always need to shutdown TWICE to keep it off
It always boots up after first shutdown and always stays off after 2nd Attempt..rly weird..
