Recharging the Backup Battery
The backup battery charges while the main battery is
charging. It usually takes approximately 4.5 hours to recharge
both the main and backup batteries together.
A full 10 hours charging time is required under either of these
circumstances:
this is the first time you have used your MobilePro
the main battery has been in a depleted state for a
prolonged period.
In these cases allow ten hours for both the main and backup
batteries to charge, even if the LED indicator on the front of
the MobilePro lights green before the full ten hours are
passed.
To protect your data, do not use the system until the backup
battery is charged.
To recharge the main and backup batteries, connect the AC
adapter. See the section, Connecting the AC Adapter in
Chapter 1.
MobilePro Power Management
When your MobilePro is connected to an AC power source
and the main battery is removed from the system, be sure to
replace the main battery before disconnecting the AC adapter
to prevent possible data loss.
