Calibrating a Battery Pack
When to Calibrate
Even when a battery pack is heavily used, calibrating it should
not be necessary more than once a month. It is not necessary to
calibrate a new battery pack before first use. Calibrate the battery
pack under the following conditions:
■ When battery charge status displays seem inaccurate.
■ When you observe a significant change in battery run time.
■ When the battery pack has been unused for one month
or
more.
How to Calibrate
To calibrate a battery pack, you must fully charge, fully
discharge, and then fully recharge the battery pack.
Charging the Battery Pack
A battery pack can charge whether the notebook is off or in use,
but it will charge faster when the notebook is off.
To charge the battery pack:
1. Insert the battery pack into the notebook.
2. Connect the notebook to an AC outlet or an optional adapter.
(The battery light on
the notebook is turned on.)
3. Leave the notebook connected to external power until
the
battery pack is fully charged. (The battery light on the
notebook will then be turned off.)
