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.
Using the Power control panel
The Power control panel displays information about the current
state of your battery and allows you to control options that can
