Battery Packs

Plug an optional Aircraft Power Adapter into the notebook and into the in-seat power supply available on some commercial aircraft. (The optional Aircraft Power Adapter can run the notebook but cannot charge a battery power.)

Dock the notebook in an optional Port Replicator.

When No Power Source Is Available

To resolve a low-battery condition when no power source is available, select one of the following options:

Initiate Hibernation.

In Windows 2000 Professional, select Start > Shut down > Hibernate, then select the OK button.

In Windows XP, select Start > Turn Off the Computer > Hibernate. (If the Hibernate option is not displayed, press the shift key).

Save your work and shut down the notebook.

When the Notebook Cannot Exit Hibernation

To resolve a low-battery condition if the notebook lacks the power to exit Hibernation:

1.Insert a charged battery pack or connect external power.

2.Exit Hibernation by briefly pressing the power button.

Calibrating a Battery Pack

To calibrate a battery pack manually, follow the instructions in the following sections. To initiate an unattended calibration in an optional Universal Charger, follow the instructions included with the device.
