Activating the backup battery

The backup battery protects your data when the main battery runs out of power. The backup battery does not provide enough power to operate your HP Jornada, but it will preserve your data while you replace the main battery or while you connect to AC power to recharge. The 3-V CR2032 coin-cell backup battery is preinstalled. When you begin using your HP Jornada, you do not need to remove the cover plate or install the backup battery—simply activate the backup battery by using the following procedure.
