Abstract: PROBLEM TO BE SOLVED: To provide a low-cost and small-size power supply switching apparatus which can surely supply power, even when the power supply from outside is shut off and also provided a computer which avoids shutdown caused by shutting-off of the power from the outside. SOLUTION: The power supply switching apparatus comprises an AC adaptor detection circuit 110 and a temporary power supply circuit 112, which are disposed on a power supply line L, and a battery switching circuit 114. The AC adaptor detection circuit 110 detects the shut-off of the power supplied from the outside via an AC adaptor 62 and outputs the detection result as a #AC- ADAP signal. The temporary power supply circuit 112 temporarily supplies power to a DC-DC converter 66, when the power from outside is shut off. The battery switching circuit 114 switches the states of FETs 1-4, and both a main battery 64A and a secondary battery 64B are connected to the DC-DC converter 66 in linkage with a change of the #AC-ADAPT signal, when the AC adaptor 62 is disconnected.
