Chapter 3. Using External Devices
Your computer has many built-in features and connection capabilities.
Attention:
Do not connect or disconnect any external device cables other than USB cables
while the computer power is on; otherwise, you might damage your
computer. To avoid possible damage to attached devices, wait at least five
seconds after the computer is shut down to disconnect external devices.
Connecting a Universal Serial Bus (USB) Device - - - - -
Your computer comes with three Universal Serial Bus compatible with USB 2.0
or USB 1.1 devices such as a keyboard, mouse, camera, hard disk drive, printer,
and scanner. USB allows devices to be connected and disconnected without
rebooting the computer (hot swapping), and allows specific classes of hardware
to be used without requiring individual device drivers to be installed.
