Issue:
The HP Jornada 680/680e Handheld PC may not display the welcome screen properly when connecting to power for the first time (main battery or AC power) or after a full reset. The screen may appear blank, display only a portion of the picture, or display vertical lines. If this occurs, the LCM display is not defective.
Solution
Perform the following steps:
  1. Remove the main battery/AC input.
  2. Replace the battery/AC input.
  3. Press the reset button to perform a soft reset. The unit will now boot up normally and the welcome screen will appear.
