16 Hewlett-Packard Jornada 420 Palm-size PC

Managing battery power

Because the data and files you save on the HP Jornada are stored in RAM, it is extremely important that you maintain a continuous power supply to the HP Jornada at all times. If the HP Jornada runs out of power, all information you have entered is lost. Although the Windows CE operating system and programs are stored in ROM and cannot be erased, any custom settings and programs you have added are lost.

When taking out the battery, keep in mind that when the P/PC is without power, data retention is guaranteed for only 1 minute. You do not need to take out the main battery except to replace it with a spare battery (F1287A).

The HP Jornada uses a rechargeable lithium-ion battery, which supplies power whenever the P/PC is not connected to AC power. Under normal operating conditions, the battery should last for up to 6 hours of continuous use without recharging. Battery life varies, however, depending on how you use the P/PC.

You should respond immediately when a message warning of low battery power is displayed. When the battery power is low, simply connect the HP Jornada to AC power to recharge.
