Chapter 3 Managing battery power 17
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.
