Powering Your hp Jornada

Because the data and files you save on your hp Jornada are stored in RAM, maintaining a continuous power supply to the hp Jornada at all times is extremely important.

The preinstalled programs will not be deleted even if your hp Jornada suffers a loss of power; however, any custom settings and programs you have added will be erased.

To safeguard data against loss in the event of power failure, you can save or back up files to the hp safe store folder. The hp emergency backup application automatically saves your PIM databases to the hp safe store folder. For more information, see “Backing Up and Restoring Data” and “Managing Memory” in chapter 6.

Main Battery

The hp Jornada lithium-polymer battery pack (the main battery) provides power to your hp Jornada while it is not connected to ac power. Under typical usage conditions (if you do not use the backlight), the fully charged main battery should provide power for up to 14 hours of use. Actual battery life will vary depending on how you use your hp Jornada. Some functions, such as listening to music, using the backlight, or operating CompactFlash cards, use considerable power and may reduce this time significantly.

The hp Jornada extended battery pack, which offers twice the battery life of the standard battery, is available as an optional accessory.

The main battery is charged whenever your hp Jornada is connected to an ac power source—either the ac adapter or the USB cradle. Connect your hp Jornada to ac power or place it in the cradle when it is not in use, to
