the hard drive. The light might also be on when devices such as your CD player
are operating.
Press to turn on the computer.
NOTICE:
To avoid losing data, do not use the power button to turn off the computer.
Instead, perform an operating system shutdown.
Open the door to use the front-panel connectors.

The front door is removable; if you remove it or accidentally knock it off its hinges,
it snaps back in place. For instructions on how to reattach the door, see page 58.
