To replace the battery:

1.  Observe the precautions in ‘Before You Begin’

(Chapter 2).

2.  Turn off all peripheral devices connected to the

computer.

3.  Turn off the computer and unplug the power cable.

4.  Remove the computer top and access covers.

5.  With your fingers, gently pry the battery free from its

socket. Note the "+" and "-" orientation of the battery.

6.  Install the new battery in the socket, orienting the “+”

and “-” correctly.

7.  Replace the computer cover.

USB Interface Support

The USB ports permit the direct connection of two USB
peripherals without an external hub. If more devices are
required, an external hub can be connected to either of the
built-in ports. The motherboard supports the standard
universal host controller interface (UHCI) and uses standard
software drivers that are UHCI-compatible.

Features of the USB include:

♦ 

Support for self-identifying, hot-pluggable peripherals

♦ 

Automatic device configuration

♦ 

Support for synchronous and asynchronous transfers
over the same set of wires

♦ 

Support for up to 127 physical devices

♦ 

Bandwidth and low latencies appropriate for telephony,
audio, and other applications

♦ 

Error handling and fault recovery built into protocol
