HP Jornada 820 Series Handheld PC - How to Conserve Battery Power
How do you conserve battery power in an HP Jornada 820 Series Handheld PC?
Under normal circumstances, the HP Jornada Standard Battery should provide up to 10 hours of continuous use. However, certain tasks require more battery power and deplete the main battery faster. Follow the tips below to maximize battery life.
Reduce the brightness of the display. Compensate for low light by increasing the contrast.
Shorten auto-suspend time. Use the HP battery control panel to set the length of continuous idle time before your HP Jornada auto-suspends. Press the On/Off key or click Suspend on the Start menu to turn off your HP Jornada when it is not in use, even for a short time.
Always use AC power when connecting your HP Jornada to your desktop PC.
note:Your HP Jornada will not auto-suspend while it is connected, so you must be careful not to allow the batteries to run down.
Turn off sounds. Use the HP Jornada settings application to mute the HP Jornada speaker, or use the Sound & Volume control panel to turn on only the most necessary system sounds.
Set the screen to dim automatically after a short time. Use the HP battery control panel to set the auto-dimming feature.
Connect to AC power when using an external monitor. Using an external monitor consumes considerable power and can drain your battery.
Avoid using PC Cards while on battery power. Some PC Cards (especially PC Card modems) use considerable power and will quickly drain your battery.
Disconnect USB device when not in use. USB devices use considerable power and will quickly drain your battery.
