Diagnosis / Remedy
Battery power is too low to run device.
Connect to AC power, and then turn on
your HP Jornada. (Charge the battery
regularly to avoid running out of battery
power.)
You are using your HP Jornada in ways
that drain the batteries quickly.
See the Managing battery power
section in chapter 7.
The HP Jornada is designed to stay on
while connected to a computer.
This is the correct behavior. No action
is needed.
Batteries are too low to run device. When
a critically low battery-power condition is
encountered, the HP Jornada initiates a
safety shutdown. Connect to AC power
and charge the main battery. Do not
remove the backup batteries before
charging the main battery.
HP Jornada is locked up. Connect the
HP Jornada to external power, and
perform a soft reset. (See the Resetting
section in this chapter.)
(Caution: You may lose any unsaved data
when performing a soft reset.)
