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

Charge the battery pack while the notebook is on. To charge the battery pack:

1.Insert the battery pack into the notebook.

2.Connect the notebook to external power through the

AC adapter. (The notebook battery light is on as the battery pack charges.)

3.Leave the notebook connected to external power until the battery pack is fully charged. (The notebook battery light is then turned off.)

Discharging the Battery Pack

ÄCAUTION: To prevent loss of work, save your work before beginning an unattended discharge procedure.

The notebook must remain on throughout the discharge process. The battery pack can discharge whether or not you are using the notebook, but the battery pack will discharge faster if the notebook is in use.

If you use the notebook occasionally during the discharge process described in the following procedure and have set energy-saving timeouts, expect the following performance from your system during the discharge:

■Any unsaved work from your current session will be lost when the battery pack is fully discharged and the notebook is shut down.

■The system will not turn off a connected optional monitor.
