Maintaining power to the HP

 Jornada Jornada  Jornada
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.

The rechargeable backup battery is a permanent part of the
HP Jornada, so you do not need to install or replace it.
The backup battery is being charged automatically when the
P/PC is connected to AC power. Continue to charge until the
backup battery level is “good.” While charging, backup battery
low messages may continue to appear.
Do NOT replace your main battery when the backup battery is
low.
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.
Viewing the remaining battery power

To charge the batteries
1. Connect the HP Jornada to AC power.
The AC Charging LED indicates the charging status of the main
battery:
•Amber—Indicates that the battery is charging (connected to
AC power).
•Green—Indicates that the battery is fully charged.
The AC Charging LED is illuminated only if the P/PC is
connected to AC power.

Changing the main battery
Changing the main batteryChanging the main battery Changing the main battery
Follow this procedure when you replace the main battery with a
spare battery (accessory F1287A).
Do NOT replace your main battery when the backup battery is
low  or data loss may occur.
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).
To change the main battery
1. Turn off the P/PC.
2. Release the battery door by pushing the stylus into the
small hole above the door. Then, slide the door down and
off. See the figure in the
Installing the battery section in chapter 2.
3. Slide the old battery out of the battery slot.
4. Slide the new battery into the battery slot. If the battery
does not slide in easily, check the battery orientation
and try again. If you are putting the battery in correctly,
you do not need to force it.
5. Replace the battery door, and slide it up until it snaps
shut.
6. Turn on the P/PC.
The rechargeable backup battery is a permanent part of the HP
Jornada, so you do not need to install or replace it.
Before using battery power, charge the battery by connecting
the AC adapter.
You can use the P/PC while charging. Charging the battery
takes approximately 3 to 4 hours.

The switch on the battery does not have any electrical function.
When the battery is drained, you can flip the switch so that the
red dot shows. This can help to remind you that the battery
needs to be recharged, which is convenient if you have other
batteries.

The Power tab lets you customize how and when your P/PC
suspends operation to help maximize battery life:
•Touch screen to power on—Select this option to allow your
P/PC to awake from suspend mode when you tap the screen or
hard icon panel.
The Touch screen to power on option is checked by default.
When you uncheck this option, you are no longer able to use
the hard icon panel to power on the P/PC.
•Suspend while on battery power—To conserve battery
power, your P/PC automatically suspends operation after a
period of continuous idle time while running on battery power.
Select the amount of idle time from the dropdown list.
•Enable suspend while on AC power—Select this option to
automatically suspend operation after a period of continuous
idle time while running on AC power. Select the amount of

conserves battery power by automatically dimming the
backlight.
•Automatically dim while on AC Power—Select this option
to automatically dim the backlight after a period of continuous
idle time while running on AC power. Select the amount of

wait for the P/PC to start up or shut down; you can start working
immediately by pressing the On/Off button at the lower right
corner of the P/PC.
Alternately, you can turn on the P/PC by:
•Pressing the Start button
•Pressing the Record button
•Holding the stylus down on one of the hard icons
•Tapping the screen
When you are finished, turn off the P/PC by pressing the On/Off
button. Turning off the HP Jornada simply suspends operation.
When you turn it on again, you can start working where you left
off.

To conserve battery power, you can set the HP Jornada to
auto-suspend after a preset period of continuous idle time. By
default, the P/PC auto-suspends after 3 minutes while running
on battery power. (For more information on auto-suspend and
tips for conserving battery power, see the Optimizing
battery life section in chapter 3.)
