2. Very Low Battery Warning
Very Low battery condition occurs at 5 percent power
remaining. The orange battery status LED indicator blinks
and the system beeps at
4 -second intervals.
When the MPC TXTbook™ PC warns you of its low battery
condition, you will have about three to five minutes to save
your current work.
Do not expose battery packs to
temperatures below 0 degree Celsius (32 degree F) or
above 60 degree C (140 degree F). This may adversely
affect the battery pack.
Charging the Battery and Charging Time
To charge the battery, plug the AC adapter into the MPC
TXTbook™ PC and an electrical outlet.
For a totally discharged battery, it will take approximately
two hours to charge to 90% capacity, and approximately
three hours to 100% capacity while MPC TXTbook™ PC is
powered OFF. It will take about 5 hrs to charge the battery
to 100% capacity while MPC TXTbook™ PC is powered on.
When the battery is fully charged, the battery charge
indicator becomes green.
If system runs at heavy loads or in a
high temperature environment, the battery may not be
fully charged. You need to continue to charge it with the
AC adapter plugged in until the charging LED turns
green.
System will not charge battery when
temperature exceeds 40C.
