ABSTRACT:
A system includes a computer main body, and an expansion unit detachably connected to the computer main body, for supplying a power to the computer main body and expanding a function of the computer. A power in the expansion unit is consumed in the expansion unit prior to power supply to the computer main body so as to stably supply a power to circuit components of the expansion unit. The expansion unit includes an expansion connector to which at least one expansion board is arbitrarily detachably connected, a power supply for supplying the power to the circuit components including the expansion circuit boards and to the computer main body, and a switch for detecting a power supplied from the power supply to the circuit components and stopping power supply to the computer main body by the power supply when the power exceeds a predetermined value.
