This just started yesterday.
When I click Shut Down from the menu it just restarts and comes back to the Home login screen. Only way I can shut down the computer is by holding the power button.
I have removed the battery. I have done a system restore to a few weeks back when things were fine.
Any ideas? Laptop is only 4 months old, running i5-2430M, 8GB RAM, 64 bit operating system.
