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 then remove the battery from the bay. 80 Setting Up and Using Your Tablet-PC
