Using the battery
Your notebook’s battery lets you use your notebook without having to plug it
into an electrical outlet. The battery recharges when the AC adapter is plugged
into your notebook and an electrical outlet.
The battery has the following characteristics:
■ Employs current battery technology standards
The computer uses a Lithium-Ion (Li-Ion) battery which does not have the
memory effect problem of Nickel Cadmium (NiCd) batteries. Li-Ion
batteries consistently provide the longest battery life.
■ Battery-low warning
When the battery charge level becomes low, the status indicator on your
notebook flashes at regular intervals. This tells you that the battery power
is critically low (and you should save your work). You can correct this
situation by recharging the battery.
Whenever possible, use the AC adapter. The battery will come in handy when
you travel or during a power failure. We recommend that you have an extra,
fully-charged battery available as backup.
Using the battery for the first time
To use the battery for the first time:
1 Plug the AC adapter into the notebook and an electrical outlet, and let
the battery fully recharge.
2 Disconnect the AC adapter and run the notebook on the battery until the
charge is used up before recharging again.
You only need to do this once or twice with a new battery or with a battery
that's been stored without being used for a long time. If the computer is
to be stored for more than two weeks, we suggest you remove the battery.
Battery power from a fully charged battery depletes in roughly a day with
the computer in Standby mode or a month in Hibernation mode or when
power is off.
