Hi. I have a Sony Vaio with USB mouse and keyboard attached. I also
use an external monitor. I can use Fn & F7 to switch between the LCD
screen and the external monitor, and I can use both simultaneously.

What I'd like to be able to do though is close the LCD screen and use
only the USB / external monitor *without* the laptop shutting down /
hibernating but I can't figure out how to do so.

Can somebody help me please?
