Display problem on NEC MobilePro 900

Hi, I just purchased a NEC MobilePro 900 used and within 15 minutes, I vertical lines appeared in the display making it difficult to see. I had fully charged it and put in a new backup battery (2023), and I tried to adjust the display every way I could think of, but the lines will not go away. Since the unit works great otherwise, I would like to know if there is a way to fix this problem since I could not find the issue in the manual. Maybe a component has gone out? It's very strange that the display was fine while I tried out a game of solitaire on it and then the display went south when I exited the program.

Backup Battery is 2032, which needs to be replaced every 2-3 weeks depending on use. Here is also a great resource for information: http://www.foxpop.co.uk/hpc/mp900_05.htm

I just bought a 900C on eBay and had the same problem. According to the seller "the video cable on the right under the hinge cover gets loose..if its reseated it will be fine..you could just press on the bottom of the hinge cover right and it will make it go away but best to reseat the cable." I haven't tried his solution yet. Mine seems to intermittent since it is working fine right now.

"Backup Battery Very Low"


NEC has identified an issue where the system can erroneously generate the "Backup Battery Very Low" message. There are two possible solutions that will eliminate this erroneous low battery warning message (the first method is the preferred solution, the second method can be used if the update file is not available). Solution I. Install a new version of the driver that controls the battery monitoring circuit. 1. Download the Low battery warning fix to your desktop. 2. Using ActiveSync or a compact Flash Card, copy FixBatt_HPC2K.EXE to the MobilePro internal disk. 3. On the MobilePro, double click the FixBatt_HPC2K icon. 4. When the message "Low Backup Battery Issue" is displayed, tap the "Patch it" button 5. When prompted turn unit over and momentarily depress the Reset button using the stylus. Solution II. Change the default power management configuration. Configure your MobilePro 900 to suspend when the LCD lid is closed on battery power and AC power. To ensure that the device suspends whenever the lid is closed, please make the following changes and perform a soft reset: 1. Go to Control Panel. 2. Open MobilePro Settings. 3. Go to the LCD Suspend/Resume tab. 4. Place a check next to "Enable suspend while on External Power." 5. Click the "Advanced" button and place a check next to "Enable suspend while on External power. 6. Click OK to close the Advanced Setting window and click OK to close the MobilePro Settings. 7. Turn unit over and momentarily depress the Reset button using the stylus. NOTE: Both the software update and power management settings are cleared on a hard reset and must be re-applied.
