Low Battery Warning 3-3
E-EQ-MX3CERG-A-ARC MX3-CE Reference Guide
Low Battery Warning
It is recommended that the Main Battery Pack be removed and replaced when it's energy depletes.
When the Low Battery Warning appears do an orderly shut down of the MX3-CE, minimizing the
operation of any installed devices and insuring any information is saved that should be.
When the unit is in an ON state, a low battery warning dialog box appears on the display and the
Batt-M LED illuminates red.
Note: Once you receive the Low Battery Warning, you have approximately 5 minutes to
perform an orderly shutdown and replace the main battery pack before the unit powers
off. The Low Battery Warning will transition to Critical Suspend before the computer
powers off.
Critical Suspend State
The Critical Suspend state or mode can only be entered because of a Main Battery Power failure.
A Main Battery Power failure can occur because the battery’s energy has been depleted or the
battery has been removed.
When the MX3-CE is in the Critical Suspend state the main battery LED illuminates, the System
LED blinks red, all peripherals are shut down, the CPU clock is stopped, and power is removed
from the PCMCIA card(s). The MX3-CE is saving the state prior to the backup battery failing and
cannot be used.
If a new fully charged main battery is installed before the timer expires the MX3-CE will transition
to the Suspend state. To resume operation tap the Power key.
If the Off Timer expires the MX3-CE will turn itself off and all unsaved information is lost. Insert
a fully charged main battery and press the Power button to turn the MX3-CE back on.
Note: The Off Timer can be configured in the Control Panel.
Backup Battery
The MX3-CE has a backup battery that is designed to provide limited-duration electrical power in
the event of Main Battery Pack failure. The Backup Battery is a 50 mAh Nickel Cadmium (NiCd)
battery that is factory installed in the unit. The need for recharging of the backup battery is
automatically detected and controlled by the MX3-CE. The energy needed to charge the backup
battery comes from the Main Battery.
It takes several hours of operation before the Backup Battery is capable of supporting the
operation of the computer. The duration of Backup Battery life is dependent upon operation of the
MX3-CE, it’s features and any operating applications.
The backup battery is replaced by LXE. See Chapter 1 “Introduction” section titled “Contacting
LXE”.
Maintenance
Note: Make sure there is a fully charged main battery in the MX3-CE before running the
Backup Battery Discharge Utility. The backup battery can be discharged and charged
while the MX3-CE is receiving external power through the Power Jack or from a
powered cradle.
