Extending battery life

To maximize the life of your battery pack:

At least once a month, disconnect the computer from a power source

and operate it on battery power until the battery pack fully discharges.

Before doing so, follow the steps below.

If you have extra battery packs, rotate their use.

If you will not be using the system for an extended period, more than

one month, remove the battery pack.

Disconnect the AC adaptor when the battery is fully charged.

Overcharging makes the battery hot and shortens life.

If you are not going to use the computer for more than eight hours,

disconnect the AC adaptor.

Store spare battery packs in a cool dry place out of direct sunlight.

Replacing the battery pack

The battery pack is classified as a consumable item.The operating life of

the battery pack will gradually reduce through repeated charging and

discharging. It will need to be replaced when it reaches the end of its

operating life.
You might also replace a discharged battery pack with a charged spare

when you are operating your computer away from an AC power source.

This section explains how to remove and install the battery pack.

1. Turn off the computer’s power.
2. Disconnect the AC adaptor and turn on the computer’s power. If it

does not turn on go to step 4.

3. Operate the computer on battery power for five minutes. If the

battery pack has at least five minutes of operating time, continue

operating until the battery pack is fully discharged. If the Battery

indicator flashes or there is some other warning to indicate a low

battery, go to step 4.

4. Connect the AC adaptor to the computer and the power cord to a

power outlet. The DC IN 15V indicator should glow green, and the

Battery indicator should glow orange to indicate that the battery

pack is being charged. If the DC IN 15V indicator does not glow,

power is not being supplied. Check the connections for the AC

adaptor and power cord.

5. Charge the battery pack until the Battery indicator glows green.
