POWER SUPPLY
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.
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 nor-
mal, but may cause injury with prolonged contact.
Keep the adapter connected whenever possible. The AC adapter charges the battery when it is connected,
whether the computer is on or off.
Do not attempt to disassemble the AC adapter. The AC adapter has no user-replaceable or service-
able parts inside. Dangerous voltage in the AC adapter can cause serious personal injury or death.
The AC adapter is intended for use with a computer and must meet EN609050 standards.
Replace the cord if it becomes damaged. The cord must be rated for at least 250VAC at 10 amps,
and must indicate international safety agency approval. The plug must be a type appropriate for the
country where it is used. Check with your local dealer for HAR type 18 AWG, 2 conductor cord, or
better. Obtain replacement cords at an authorised service centre. The replacement must be of the
same type and voltage rating as the original cord.
Connecting the AC Adapter
Connect the AC adapter as follows:
The power port on your computer is indicated by this
symbol:
1. Connect the AC adapter cable to the power port on your
computer.
2. Plug one end of the AC power cable into the AC adapter
and the other end into a properly grounded 120- or 240-
volt, 50 or 60-Hz wall outlet (the adapter automatically
detects and adjusts to the input voltage).
