Taking care of your battery
❖
Do not expose the battery pack to fire. The battery pack could
explode.
Maximizing 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

❖
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.
Turn off the computer's power.
Disconnect the AC adaptor and turn on the computer's
power. If it does not turn on, go to step 4.
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 light LED flashes or there is
some other warning to indicate a low battery, go to step 4.
Connect the AC adaptor to the computer and the power
cord to a power outlet. The DC IN or AC power-light
LED should glow green, and the Battery LED should
glow amber to indicate that the battery pack is being
charged. If the DC IN or AC power-light indicator does
not glow, power is not being supplied. Check the
connections for the AC adaptor and power cord.
Charge the battery pack until the Battery LED glows
green.
