Chapter 2 Getting started 21

Use the AC adapter to plug your HP Jornada into external power whenever possible, especially when connecting to a desktop PC, using a PC Card modem, NIC, or other peripheral, or letting the LED indicator flash for extended time periods.

Installing the backup batteries

The two CR2032 coin-cell backup batteries protect your data when the main battery runs out of power. The backup batteries do not provide enough power to operate your HPÊJornada, but they will preserve your data while you replace the main battery or while you connect to AC power to recharge.

To prevent loss of data, replace the backup batteries as soon as a warning message appears on your screen indicating that backup battery power is low. See the Managing battery power section in chapterÊ7.)

To install the backup batteries

1.Slide down the cover plate from the backup battery compartment on the left side of your HP Jornada (see diagram).

2.Remove the battery tray from the compartment by pulling the ribbon attached to the cover plate.

3.Place the two backup batteries in the tray with the positive side facing up.
