To connect a USB device
Your computer’s universal serial bus (USB) provide a bi-directional serial interface for
adding peripheral devices such as game controllers, serial and parallel ports, and scanners
on a single bus.
• Attach the device’s USB cable to one of the computer’s USB ports. Windows
automatically recognizes the USB device. Some USB devices can be connected to the
computer in series—this is called a daisy-chain connection.
Note
If you have problems making this connection, contact the device manufacturer and the
HP Customer Care Web site (www.hp.com/go/support) for the latest version of the
driver for the device.
To connect an audio device
Your computer includes a built-in microphone (just in front of the blue sleep button) that
you can use to record voice, sound, and music. You can also plug in a stereo input source
(such as a CD player), an external microphone, external speakers, or headphones.
CAUTION
The audio jacks are three-terminal stereo jacks. They are not compatible with twoterminal mono plugs. Connecting a mono plug into the speaker-out jack may
damage the computer.
• Attach the audio cable to the corresponding audio port on the computer.
Note
When you plug a device into the external microphone port, the built-in microphone
automatically turns off. When you plug a device into the audio out port, the built-in
speakers automatically turn off.
