Before using battery power, charge the battery overnight by connecting the AC adapter (see the Connecting the travel cable and AC adapter section in this chapter). While charging, you may see backup battery low messages. These do not appear once the battery is fully charged. If you do not charge overnight, the backup battery low messages may continue to appear. You can use the P/PC while charging.
About the backup battery
The rechargeable backup battery is a permanent part of the HP Jornada, so you do not need to install or replace it.
The backup battery is being charged automatically when the P/PC is connected to AC power.
Make sure you connect to AC power to charge as soon as you see a backup battery low warning. Continue to charge until the backup battery level is “good” (check the Status tab of the Power panel; see the Using the Status tab section in chapter 3).
Do NOT replace your main battery when the backup battery is low.
Connecting the travel cable and AC adapter
You can operate the HP Jornada on AC power using the AC adapter. The AC adapter accepts voltages from 100 V to 240 V, so you can use it anywhere in the world. However, you may need a plug adapter to accommodate different electrical outlets.
