start charging, charging starts on the battery pack in the battery
pack bay. When it is fully charged, charging starts on the battery
pack installed in the UltraBay.
Charging with the AC Adapter
Note:
When carrying your computer without
the AC Adapter, carry with you a fully
charged battery pack for maximum
operating hours. You can also have
an optional battery pack and use two
battery packs for operation.
When the AC Adapter is connected
and the power remaining in the
installed battery pack is less than a
certain amount, discharging and then
charging of the battery pack starts
automatically. The discharge LCD
indicator appears .
