Battery Pack
The battery pack is the internal power source for the Tablet PC. It is
rechargeable using the AC adapter.
The operating time of a fully charged battery pack depends on how you are
using the Tablet PC. When your applications often access peripherals, you
will experience a shorter operating time.
NOTE: Care and maintenance information for the battery is provided in the
“Battery Pack Guidelines” section in Chapter 7.
Charging the Battery Pack
NOTE:
z Charging will not start if the battery’s temperature is above 50 qC (122 qF)
or below 2 qC (28 qF); the charging process will stop if the battery’s
temperature gets above 60 qC (140 qF) or below 4 qC (25 qF). To avoid
damaging the battery under this situation, disconnect the AC adapter
and wait for the battery to return to room temperature before charging
again.
z During charging, do not disconnect the AC adapter before the battery
has been fully charged; otherwise you will get a prematurely charged
battery.
To charge the battery pack, connect the AC adapter to the Tablet PC and an
electrical outlet. The Battery Charge Indicator (
) on the Tablet PC glows
amber to indicate that charging is in progress. You are advised to keep the
Tablet PC power off while the battery is being charged. When the battery is
fully charged, the Battery Charge Indicator glows green.
It takes approximately 3 hours to fully charge the Li-Ion battery pack at a
room temperature of 25 qC (77 qF) (may need a longer charging time at
lower temperatures).
CAUTION: After the Tablet PC has been fully recharged, do not immediately
disconnect and reconnect the AC adapter to charge it again. Doing so may
damage the battery.
