Troubleshooting

Resolution
Recharge the main battery (see
"Connecting the AC Adapter" in
Chapter 1).
Connect the AC adapter to the unit when
using PC cards that require large
amounts of energy.
Make sure that the main battery is
installed (see "Installing the Main
Battery" in Chapter 1).
Check that the AC adapter connections
are secure.
Verify that the AC outlet being used is
working. Do this by plugging in another
electric device, such as a lamp.
Check that the battery lock is in the
locked position (see "Installing the Main
Battery" in Chapter 1).
Reset the unit (see "Resetting the
MobilePro" in Chapter 4).
If you have installed handwriting
recognition software, be sure that you
have not set the "disable keyboard"
parameter in that software.
Check that you installed the USB driver
from the Application and Driver CD (see
"Loading USB Files" in Chapter 1).
Verify that the MobilePro PC Connection
setting is set to "USB Connection" (see
"Connecting to Your PC via USB Cable"
in Chapter 1).
