Power and Power-Up Modes

Note

1. Never remove the battery pack while the Wake-up on LAN function is

enabled. Data will be lost. Before you remove a battery pack, disable

the Wake-up on LAN function.

2. To ensure the battery pack maintains maximum capacity, operate the

computer on battery power once a week until the battery pack is fully

discharged. Refer to the section

Extending battery life

in this chapter for

procedures. If the computer is continuously operated on AC power for

an extended period, more than a week, the battery might fail to retain a

charge. It might not function efficiently over the expected life of the

battery pack and the Battery indicator might not indicate a low-battery

condition.

3. After the battery pack is charged, avoid leaving the AC adapter

connected and the computer turned off for more than a few hours at a

time. Continuing to charge a fully charged battery pack can damage the

battery.

Charging the batteries

When the power in the battery pack becomes low, the Battery indicator

flashes amber indicating that only a few minutes of battery power remain. If

you continue to use the computer while the Battery indicator flashes, the

computer enables Hibernation mode (so you don't lose data) and

automatically turns off.
You must recharge a battery pack when it becomes discharged.

Procedures

To recharge a battery pack while it is installed in the computer, connect the

AC adapter to the DC IN socket and plug the other end into a working

outlet.
The Battery indicator glows amber when the battery is being charged.
