If you have extra batteries, rotate their use.
If you will not be using the system for an extended period
(more than one month) remove the battery.
Disconnect the AC adapter 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 adapter.
Store spare batteries in a cool dry place out of direct
sunlight.
Charging batteries
The main battery needs to be charged before you can use it to
power the computer. You can charge the battery using your
computer, or you can use an optional battery charger.
Operate the computer on battery power for five
minutes. If the battery has at least five minutes of
operating time, continue operating until the battery 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 adapter to the computer and the
power cable to a power outlet. The DC-IN (if
applicable to your system) or AC power light on your
computer will glow green, and the battery light will
glow amber to indicate that the battery is being
charged. If the DC-IN or AC power light indicator on
your computer does not glow, power is not being
supplied. Check the connections to the AC adapter
and power cable.
Charge the battery until the battery light glows green.
