An information processing apparatus includes a first power source generation unit configured to generate a first voltage lower than a predetermined supply voltage based on at least power supplied from a battery, from a supply voltage power source of the predetermined supply voltage, and output the first voltage as a first voltage power source; a second power source generation unit configured to generate a second voltage lower than the first voltage and used when at least a system is activated, and output the second voltage as a second voltage power source; and a power source switching unit configured to switch the supply voltage power source with the first voltage power source to supply the first voltage power source to the second power source generation unit, and cause the second power source generation unit to generate the second voltage power source from the first voltage power source.
