Abstract
A method for docking/undocking a portable computer to/from an expansion unit is disclosed. The portable computer includes a main battery, and the expansion unit includes a second battery. In response to an eject event, the condition of the second battery is determined. If the second battery is in a discharging condition, a power supply route is switched from the second battery of the expansion unit to the main battery of the portable computer. If the second battery is in a charging condition, the charging condition is suspended. At this point, a hot undocking of the portable computer from the expansion unit can be performed.
