Turn off sounds—Use the HP settings application to mute the HP Jornada speaker, or use the Sound & Volume control panel to turn on only the most necessary system sounds.

Avoid using PC Cards while on battery power— Some PC Cards (especially PC Card modems) use consid- erable power and will quickly drain your battery.

Use the AC adapter to plug your HP Jornada into external power whenever possible, especially when connecting to a desktop PC, when using a PC Card modem, network interface card (NIC), or other peripheral. Do not let the alarm notification LED flash for a long time.
