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 chapter2.
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.
