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.
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 Battery indicator should glow orange to indicate that the
battery pack is being charged. If the Battery indicator does not glow,
power is not being supplied. Check the connections of the AC adaptor
and power cord.
5. Charge the battery pack until the Battery indicator glows blue.
■
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.
■
Store spare battery packs in a cool dry place out of direct sunlight.

Replacing the battery pack

When the battery pack reaches the end of its operating life, you will need to
install a new one. The life of the battery pack is generally about 500
recharges. If the Battery indicator flashes orange shortly after fully
recharging the battery, the battery pack needs to be replaced.
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.
