Introduction
This document describes how to remove the main and backup battery
from an HP Jornada, Palmtop, or Omnigo device.
CAUTION: Removing both the backup and main
batteries will permanently erase all data if the device is not attached
to AC power.
Backup
batteries
The backup battery protects the data when the main battery runs out
of power. The backup battery should be replaced at least every six months:
sooner if the device is operated with a low main battery. If the backup
battery becomes drained, the device will begin to lose data and behave
abnormally. All backup batteries are CR2032 batteries that are generally
found wherever batteries are sold.
Main
batteries
The main battery provides power to the device when it is not
connected to AC power. Click here to buy
replacement batteries online from HP or other
retailers. Removing the main battery is one of the steps in resetting all
information on a device.
Removing HP Jornada
batteries
The information in the following table applies only to HP Jornada

CAUTION: Replacing the batteries in proper order is
