PROBLEM TO BE SOLVED: To provide an information processing apparatus achieving construction of a display device switching mechanism at a time of attachment/detachment of an expansion unit at low cost.SOLUTION: According to an embodiment, an information processing apparatus includes: a first logical circuit; a second logical circuit; and control means. The first logical circuit supplies a detection signal indicating connection of an external display to an apparatus main body and a detection signal indicating connection of the external display to an expansion unit to the input/output port exclusively and selectively. The second logical circuit, which is provided interposed between the input/output port of a display controller and the first logical circuit, switches over between supply and cut-off of the supply of the detection signal output from the first logical circuit and indicating the connection of the external display to the input/output port. The control means controls the second logical circuit to cut off the supply of the detection signal output from the first logical circuit to the input/output port for a first period if the expansion unit is attached or detached. |
