Dell D/Dock Expansion-Station - Manual (Page 15)

1 battery
2 latch release
If no computer is docked, or if the docked computer's batteries are fully charged and the computer is turned off, the
expansion starts charging the battery in the module bay immediately. The battery light below the module bay turns
green while the battery is being charged; it may start to blink when battery charge is near completion. The battery
should charge to about 80 percent of its capacity in approximately 1 hour.
If a computer is docked and turned on, the expansion station charges the computer battery fully before charging the
battery in the module bay. When the battery is fully charged, the battery light turns off.
3. When the battery is fully charged, push the latch release and remove the battery from the bay.
