80 Setting Up and Using Your Tablet-PC
NOTE: With Dell™ ExpressCharge™, when the Tablet-PC is turned off, the AC
adapter charges a completely discharged battery to 80 percent in about 1 hour and
to 100 percent in approximately 2 hours. Charge time is longer with the Tablet-PC
turned on. You can leave the battery in the Tablet-PC for as long as you like. The
battery’s internal circuitry prevents the battery from overcharging.
If the battery is hot from being used in your Tablet-PC or being in a hot
environment, the battery may not charge when you connect the Tablet-PC to
an electrical outlet.
The battery is too hot to start charging if the light flashes alternately
green and orange. Disconnect the Tablet-PC from the electrical outlet and
allow the Tablet-PC and the battery to cool to room temperature. Then
connect the Tablet-PC to an electrical outlet to continue charging the battery.
For information about resolving problems with a battery, see "Power
Problems" on page 133.
Removing the Main Battery
CAUTION: Using an incompatible battery may increase the risk of fire or
explosion. Replace the battery only with a compatible battery purchased from
Dell. The battery is designed to work with your Dell™ Tablet-PC. Do not use a
battery from other Tablet-PCs or computers with your Tablet-PC.
CAUTION: Before performing these procedures, turn off the Tablet-PC, disconnect
the AC adapter from the electrical outlet and the Tablet-PC, disconnect any modem
from the wall connector and Tablet-PC, and remove any other external cables from
the Tablet-PC.
NOTICE: You must remove all external cables from the Tablet-PC to avoid possible
connector damage.
To remove the battery:
1
If the Tablet-PC is connected to a docking device such as the optional
media base or battery slice (docked), undock it. See "Undocking Your
Tablet-PC From the Media Base" on page 212 or "Undocking Your
Tablet-PC From the Battery Slice" on page 220.
2
Ensure that the Tablet-PC is turned off or suspended in a power
management mode.
3
Slide the battery-bay latch releases on the bottom of the Tablet-PC, and
