How to Calibrate

To calibrate a battery pack, you must fully charge, fully

discharge, and then fully recharge the battery pack.

Step 1: Charging the Battery Pack

Charge the battery pack while the computer is on. To charge the

battery pack:

ÅWARNING: Do not charge the computer battery pack onboard

aircraft. Charging the battery pack may damage aircraft electronic

systems.

1. Insert the battery pack into the computer.

2. Connect the computer to the AC adapter, an optional power

adapter, or an optional expansion product, and then plug the

adapter or device into external power. (The computer battery

light is turned on.)

3. Leave the computer connected to external power until the

battery pack is fully charged. (The computer battery light is

turned off.)

Step 2: Discharging the Battery Pack

ÄCAUTION: To prevent loss of information, save your work before

beginning an unattended discharge procedure.

The computer must remain on throughout the discharge

process. The battery pack can discharge whether or not you are

using the computer, but the battery pack will discharge faster if

the computer is in use.
