Backup Battery 49
E-EQ-MX1RG-D MX1 Reference Guide
Low Battery Warning
It is recommended that the Main Battery Pack be removed and replaced when electrical power
depletes. When the Low Battery Warning sounds (alternating one second beeps) do an orderly
shut down of the unit, minimizing the operation of any installed devices and insuring any
information is saved that should be.
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.
Backup Battery
The MX1 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 MX1. 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
MX1, its features and any operating applications.
The backup battery is replaced by LXE. See Chapter 1, “Introduction”, section titled “Getting
Help”.
Backup Battery Discharge Utility
Note: Make sure there is a fully charged main battery in the MX1 before running the Backup
Battery Discharge Utility.
The NiCd backup battery should be discharged completely once or twice a year. The Main Battery
Pack will fully charge the backup battery using a trickle charge. This process will allow longer life
for the Backup Battery.
The backup battery is discharged by running the Battery Discharge Utility (BBDIS35.EXE) file
(located in the Utilities subdirectory on the MX1 – see Chapter 5, “Utilities”, for further
information). The discharge utility shows the progress of the discharging. At this time, the
program can be exited while continuing the discharge process. Normal use of the MX1 can
resume during the discharge, with the exception of Hot-Swapping the Main Battery. When the
backup battery is fully discharged, the MX1 will automatically stop the discharge process and
begin to recharge the backup battery.
DO NOT REMOVE THE MAIN BATTERY PACK from the MX1 until the backup battery is
completely discharged (with BBDIS35.EXE) in approximately 1 hour and recharged in
approximately 2.5 hours.
