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 main battery, keep in mind that when
the P/PC is without power, data retention is guaranteed for
only 1 minute, and only if the backup battery level is “good”
(check the Status tab of the Power panel; see the Using the
Status tab section in chapter 3). 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.
