136 HP Jornada H/PC UserÕs Guide

HP Jornada allows you to run on AC power using the AC adapter or to run on battery power for convenience and portability. HP Jornada uses two types of batteries. The main battery, an ÒintelligentÓ rechargeable lithium-ion battery pack, supplies power whenever your HPÊJornada is not connected to AC power. Under normal circumstances, the main battery will provide up to 10 hours of continuous use without recharging.

The backup batteries protect your data when the main battery runs down. The two coin-sized, lithium-ion backup batteries do not provide enough power to operate your HPÊJornada. They are intended only to protect your data until the main battery is recharged. When the main battery is very low, your HP Jornada will shut down, and you will be unable to restart it until you charge the battery or connect to AC power.

The battery icon in the status area of the taskbar indicates whether the HP Jornada is operating on AC or battery power and displays the status of the main battery.
