5 USB 2.0 connectors (2) For quick connections, Dell recommends using the front USB connectors for USB
devices such as digital cameras, gaming controllers, and scanners. Use the back-panel
USB connectors for USB devices that are seldom disconnected, such as USB mouse
and keyboard devices.
NOTICE: This computer supports the use of a USB hub. However, do not
connect two or more USB hubs to a USB connector. Doing so may cause the
computer to unexpectedly restart.
HINT: If you attach a USB device that was not included in your original
computer order, you may need to install a specific driver to make the device work.
Check the documentation that came with the device or contact the USB device
manufacturer for more information.

all sounds from your computer, including your CD player and computer sounds such as
beeps.

hard drive. The light might also be on when devices such as your CD player are
operating.

NOTICE: To avoid losing data, do not use the power button to turn off the
computer. Instead, perform a Windows shutdown.
