Your computer requires a constant, stable power source to keep running. If you are at home then the AC adapter
can be connected to a mains socket and used for as long as necessary. On the road, or if you simply want to avoid
trailing wires, your computer's battery can power the computer.
AC Power Adapter
Your computer can use the supplied external power adapter (a power 'brick') to run
on AC power. A power cable is provided that is appropriate for the country where
the computer was purchased.
The power adapter provides adequate power to run your computer and recharge
the battery pack at the same time.
Warning: Do not cover or place objects on the AC adapter. Keeping the
adapter clear of objects allows the adapter to cool properly during use.
Only use the AC adapter that is supplied with your computer. Although other adapters may look
similar, using them can damage your computer.
The AC adapter and the underside of the computer can become hot after prolonged use. This is
normal, but may cause injury with prolonged contact.

removed, which allows you to carry multiple batteries for long journeys, or to replace an aged battery that has lost
Note: Although the battery is charged at the factory, transit and shelf time may reduce the initial battery
charge. The first time you use your computer, connect the AC power adapter and charge the battery
Check InfoCentre to learn more about your computer's battery.
Battery life depends on how the computer is used, the battery's capacity and the computer's design. Batteries will
start to perform less effectively with age.

main battery. Turning down the screen brightness extends battery life (most computers reduce screen brightness
automatically when using battery power). Battery life is best under the following conditions:
The battery is new and fully charged.
No peripherals (such as ExpressCards) or options (such as Wireless LAN features) are active or connected to your
The computer's hard disk drive, optical drive and processor are idling or under low load.
