5.2.5 Charging the Battery
When connected to an electrical outlet, a completely
discharged battery will charge in 3 to 5 hours
(depending on whether your notebook is on or off and
what programs, if any, are running). You can leave the
battery in your notebook as long as you like. The
battery’s internal circuitry prevents the battery from
overcharging.
Before using the battery for the first time it must be charged.
Connect the computer to an electrical outlet and allow the
battery to fully charge, indicated by the battery indicator
light on the front panel of the notebook.
Once a battery pack is fully charged for the first time,
use your notebook on battery power until the battery
discharges completely. This will extend battery life, and
helps ensure accurate monitoring of battery capacity.
If necessary, the battery will be charged whenever your
notebook is connected to an electrical outlet.
The battery will not be charged if it or your notebook is too
hot, either from use or being in a hot environment. If this
occurs the battery indicator
will light red. Disconnect your
notebook from any electrical outlet, and allow it and the
battery to cool to room temperature. You can then
reconnect your notebook to the electrical outlet and charge
the battery. The battery indicator
will also light red if the
battery is bad and needs replacing.
