136 | HP Jornada H/PC User’s 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 “intelligent” rechargeable lithium-ion
battery pack, supplies power whenever your HPJornada 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
HPJornada. 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.
