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.) For information on charging the
main battery and checking battery status, refer to
the Installing the main battery section in chapter 2.
Remove the main battery and disconnect the AC
adapter, and then reinsert the main battery and
normally, and the Welcome screen will appear.
You are using your HP Jornada in ways that drain
the batteries quickly. See the Managing battery
power section in chapter 7.
Backup battery has not been activated. Check that
the tape has been completely removed from the
backup battery compartment. If necessary, remove
the cover from the backup battery compartment,
remove the tape, and reinstall the backup battery.
For more information, see the Replacing the
backup battery 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.
Main battery is too low to run device. When a
critically low-battery condition is encountered, the
HP Jornada initiates a safety shutdown. Connect to
AC power and charge the main battery. Do not
remove the backup 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 will lose any unsaved data when
performing a soft reset.)
