Maintaining your battery

Fully discharging your battery pack will allow better accuracy of
the battery meter.
To fully discharge your battery pack:
❖
Periodically, 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.
❖
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.
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 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/cable to a power outlet. The DC-IN or AC
power-light should glow white, and the battery light
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/cable.
Charge the battery pack until the battery light glows white.
