Calibrating a Battery Pack

When to Calibrate

Calibrate the battery pack whenever battery status display seems
inaccurate or whenever the battery pack has not been used for
1 month or more. It should not be necessary to calibrate the
battery pack, even if it is heavily used, more than once a month. It
is not necessary to calibrate a new battery pack before first use.

How to Calibrate

Calibration requires 3 steps:
1. Fully charge the battery pack.
2. Fully discharge the battery pack.
3. Fully recharge the battery pack.
Charging the Battery Pack
You can charge the battery pack while the notebook is in use
or off, but the battery pack will charge faster while 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
Automobile Power Adapter/Charger. (The battery light
turns on.)
3. Leave the notebook connected to AC power until the battery
pack is fully charged. (The battery light turns off.)
