"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.
