My computer no longer can shutdown without resorting to holding the power button in. Also, the restart and logoff buttons in the start menu do not work. I'm dual booting Windows 7 which shuts down perfectly so it must be a OS problem and not a hardware issue. Even if Windows asks to reboot (updates or that type of stuff) it still won't work. Any ideas would be greatly appreciated.
I found that you can FORCE a logoff or reboot or shutdown by holding the CTRL key while clicking on Logogg/Reboot/Shutdown. It's a work-around, but it's a nuisance. I've been looking for the solution for about a week now. Ray-N4GYN
