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 or an optional automobile or aircraft 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
turned off.)

CAUTION: To prevent loss of work, save your work before beginning
an unattended discharge procedure.
The notebook must remain on throughout the discharge process.

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 below 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.
