Connecting the AC adapter WARNING! To reduce the risk of electric shock or damage to the equipment: Plug the power cord into an AC outlet that is easily accessible at all times. Disconnect power from the computer by unplugging the power cord from the AC outlet (not by unplugging the power cord from the computer). If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded (earthed) 3pin outlet. Do not disable the power cord grounding pin, for example, by attaching a 2-pin adapter. The grounding pin is an important safety feature. To connect the computer to external AC power, follow these steps: 1. Plug the AC adapter into the power connector (1) on the computer. 2. Plug the power cord into the AC adapter (2). 3. Plug the other end of the power cord into an AC outlet (3). Using battery power When a charged battery is in the computer and the computer is not plugged into external power, the computer runs on battery power. When the computer is plugged into external AC power, the computer runs on AC power. If the computer contains a charged battery and is running on external AC power supplied through the AC adapter, the computer switches to battery power if the AC adapter is disconnected from the computer. NOTE: The display brightness is decreased to save battery life when you disconnect AC power. To increase display brightness, use the f3 key or reconnect the AC adapter. You can keep a battery in the computer or in storage, depending on how you work. Keeping the battery in the computer whenever the computer is plugged into AC power charges the battery and also protects your work in case of a power outage. However, a battery in the computer slowly discharges when the computer is off and unplugged from external power. Using battery power 63

Connecting the AC adapter

WARNING!

To reduce the risk of electric shock or damage to the equipment:

Plug the power cord into an AC outlet that is easily accessible at all times.

Disconnect power from the computer by unplugging the power cord from the AC outlet (not by

unplugging the power cord from the computer).

If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded (earthed) 3-

pin outlet. Do not disable the power cord grounding pin, for example, by attaching a 2-pin adapter. The

grounding pin is an important safety feature.

To connect the computer to external AC power, follow these steps:

Plug the AC adapter into the power connector

(1)

on the computer.

Plug the power cord into the AC adapter

(2)

Plug the other end of the power cord into an AC outlet

Using battery power

When a charged battery is in the computer and the computer is not plugged into external power, the

computer runs on battery power. When the computer is plugged into external AC power, the computer

runs on AC power.

If the computer contains a charged battery and is running on external AC power supplied through the

AC adapter, the computer switches to battery power if the AC adapter is disconnected from the

computer.

NOTE:

The display brightness is decreased to save battery life when you disconnect AC power. To

increase display brightness, use the

key or reconnect the AC adapter.

You can keep a battery in the computer or in storage, depending on how you work. Keeping the battery

in the computer whenever the computer is plugged into AC power charges the battery and also protects

your work in case of a power outage. However, a battery in the computer slowly discharges when the

computer is off and unplugged from external power.
