12 Hewlett-Packard Jornada 420 Palm-size PC
This view of the left side of the HP Jornada shows how to
insert the battery.
To install the battery
1. Release the battery door by pushing the stylus into the
small hole above the door. Then, slide the door down and
off.
2. Slide the 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.
3. Replace the battery door, and slide it up until it snaps
shut.
After you install the battery, the HP Jornada turns on
automatically. Before using your P/PC on battery power,
though, you should 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. For information on
connecting the AC adapter, read the next sections.
