Delete files and voice memos you do not need, or transfer
them to your desktop PC for storage and delete them from
your HP Jornada.
You can increase the storage memory by adding a memory module on a CompactFlash or
PC card. For more information, see the Accessories section in this chapter.
Managing battery power
Because the data and files you save on your HP Jornada are
stored in RAM, it is extremely important that you maintain
a continuous power supply to your HP Jornada at all times.
If your HP Jornada runs out of power, all information you
have entered will be lost. The Windows CE operating system
and programs are stored in ROM, and cannot be erased;
however, any programs you have added and custom settings
in existing programs will be lost.
Data stored on a PC Card or CompactFlash Card will be saved, even if your H/PC loses
power. To protect your data, back up regularly to a PC Card or CompactFlash Card by
using HP backup.
HP Jornada uses two types of batteries. The main battery
supplies power whenever your HP Jornada is not connected
to AC power. The backup battery protects your data when
the main battery is not installed (for instance, while you
exchange the main battery).
Main battery
The main battery is the HP Jornada Standard Battery, a
rechargeable lithium ion battery pack. Use only the
HP Jornada Standard Battery (HP F1281A) or the
HP Jornada Extended Battery (HP F1282A) with your
HP Jornada. These batteries are designed only for use with
the HP Jornada 680/680e and should not be used to power
other devices.
