Removing and Installing Parts
The drive activity light is on when the computer reads data from the CD or DVD
drive.
(On computers with an optional floppy drive.)
The hard-drive light is on when the computer reads data from or writes data to the
hard drive. The light might also be on when a device such as your CD player is
operating.
Use the headphone connector to attach headphones and most speakers for
listening to all sounds in your computer, including your CD player and system
sounds such as beeps.
Use the front USB connectors for devices that you connect occasionally, such as
joysticks or cameras.
It is recommended that you use the back USB connectors for devices that typically
remain connected, such as printers and keyboards.
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.
The power light illuminates and blinks or remains solid to indicate different states.
For more information, see page 28.
The floppy-drive light is on when the computer reads data from or writes data to
the floppy drive. Wait until this light turns off before you remove the floppy disk

Move the dial to adjust the volume of your CD or DVD disc.
Use the headphone connector to attach headphones to the CD or DVD drive.
Your headphones won't work if the drive is operating in digital mode. To disable
digital mode, see "No sound from headphones" on page 32.
The tag is used to identify your computer when you access the Dell Support
