							Chapter 7  |  Optimizing your HP Jornada  |  135
Under normal circumstances, the main battery will provide
up to 7 hours of continuous use without recharging. Actual
battery life will vary depending on screen brightness, what
applications you use, and operating conditions. When the
main battery runs very low, your HP Jornada will shut
down, and you will be unable to restart it until you replace
the main battery, recharge the battery, or connect to AC
power.
When you replace the main battery, your new battery must
be charged before your HP Jornada will turn on. For infor-
mation on charging the main battery, refer to the Connect-
ing the AC adapter section in chapter 2.
Ensure that the backup battery is in good condition before you remove the main battery.
If the backup battery is low or you are not sure, connect to AC power before you remove
the main battery.
To replace the main battery
1. Turn off your HP Jornada and disconnect the sync
cable if it is attached.
2. Slide the audio lock to the left if it is unlocked.(No
green dot should be seen. The green dot indicates
that the audio buttons are unlocked.)
3. Slide the battery release button on the bottom of the
HP Jornada.
4. Pull the original battery pack away from the device.
5. Insert the new battery pack and push firmly until it
clicks into place.
Backup battery
The coin-sized, lithium ion backup battery does not provide
enough power to operate your HP Jornada. It is intended
only to protect your data until the main battery is re-
charged.

Ensure that the main battery is charged before you remove the backup battery. If the
main battery is low or you are not sure, connect to AC power before you remove the
backup battery.
To replace the backup battery
1. Using a small, Philips screwdriver, unscrew the
cover plate from the backup battery compartment.
Be careful not to misplace the small screw.
2. Remove the backup battery.
3. Insert a new 3-V CR2032 coin cell battery into the
backup battery compartment with the positive (+)
side facing up.
4. Replace the cover plate and the screw.
Do not mutilate, puncture, or dispose of batteries in fire. The batteries can burst or
explode, releasing hazardous chemicals. Replace batteries with only the types
recommended in this User’s Guide. Discard used batteries according to the manufacturer’s
instructions.
Using the Power control panel
Use the Power control panel to check the status of your main
and backup batteries and to set options that can increase
battery life. These include setting options for power off or
auto-suspend, setting options for power on, and setting
controls to automatically dim the backlight.
To open the Power control panel
1. On the Start menu, point to Settings, tap Control
Panel, and then double-tap the Power icon.
–or–
Double-tap the power status icon in the status area of
the taskbar. 
						

							Chapter 7  |  Optimizing your HP Jornada  |  137
The power status icon appears in the taskbar only under certain conditions, such as when
battery power is low or when your HP Jornada is connected to external power.
Checking battery status
The power area in the Power control panel indicates whether
your HP Jornada is running on battery power or connected to
AC power, and displays the status of both the main and
backup batteries. In addition, the battery icon in the status
area of the taskbar indicates whether the HP Jornada is
operating on AC or battery power and displays the status of
the main battery:
Icon Indicates
Running on AC power
Main battery charging
Running on battery power, main battery low
Backup battery low
Backup battery very low
It is important that you respond immediately when a message warning of low battery
power is displayed. When the main battery is low, simply connect the HP Jornada to AC
power to recharge. (You can use your HP Jornada while the battery is charging.) When
the backup battery is low, replace it as soon as possible. It is recommended that you back
up your data and run the HP Jornada only on AC power until you have replaced the
backup battery.
Conserving battery power
Under normal circumstances, the HP Jornada Standard
Battery should provide up to 7 hours of continuous use;
however, certain tasks require more battery power and
deplete the main battery faster. Follow these tips to maxi-
mize battery life.

Setting auto-suspend
To conserve battery power, Windows CE will automatically
turn off or suspend your HP Jornada after a period of con-
tinuous idle time.
To set or shorten auto-suspend time
1. On the Start menu, point to Settings, tap Control
Panel, and then double-tap the Power icon.
–or–
Tap the HP settings hard icon, and then tap the
battery icon on the Settings tab.
2. On the Power Off tab, select Enable suspend
while on battery power.
3. In the box that appears, set the time interval before
auto-suspend.
The default idle time is 3 minutes. To change the idle
time, select a number from the list. Increasing the
idle time may decrease your battery life.
Select Enable suspend while on AC line power if you want to suspend your
HP Jornada when it is connected to AC power. You may suspend your HP Jornada while
the main battery is being recharged.
Setting power on options
You can also set options to automatically turn on your
HP Jornada when you touch the screen or open the lid;
however, these options will not cause your HP Jornada to
turn off (for example, when you close the lid).
To set power on options
1. On the Start menu, point to Settings, tap Control
Panel, and then double-tap the Power icon.
–or– 
						

							Chapter 7  |  Optimizing your HP Jornada  |  139
Tap the HP settings hard icon, and then tap the
battery icon on the Settings tab.
2. On the Power On tab, select options for turning on
your HP Jornada.
Setting the dimming control
Dimming the backlight on your HP Jornada display can
conserve battery power. Use the Dimming Control tab to
set options for automatically dimming the backlight while on
battery power or while connected to AC power.
To set automatic dimming
1. On the Start menu, point to Settings, tap Control
Panel, and then double-tap the Power icon.
2. On the Dimming Control tab, select Automati-
cally dim while on battery power and/or Auto-
matically dim while on AC power.
3. Select a time interval from the list to set how long
your HP Jornada must be idle before the backlight is
dimmed.
Other tips for conserving battery power
•
Reduce the brightness of the display—Compensate
for low light by increasing the contrast. (See the Using
the HP settings application section in this chapter.)
Use the Power control panel to set the auto-dimming
feature.
•Suspend frequently—Use the Power control panel to
shorten the length of continuous idle time before your
HP Jornada auto-suspends. Press the On/Off key or tap
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 that your
HP Jornada will not auto-suspend while it is connected.

•Turn off sounds—Use the HP settings application to
mute the HP Jornada speaker, or use the Sound &
Volume control panel to turn on only the most necessary
system sounds.
•Avoid using PC Cards while on battery power—
Some PC Cards (especially PC Card modems) use consid-
erable power and will quickly drain your battery.
Use the AC adapter to plug your HP Jornada into external power whenever possible,
especially when connecting to a desktop PC, when using a PC Card modem, network
interface card (NIC), or other peripheral. Do not let the alarm notification LED flash for a
long time.
