According to one embodiment, an information processing apparatus includes an amplifier provided in a body and amplifying a sound signal to output sound from a speaker, a first system including a storage storing a first sound data and a sound device which generates an analog sound signal from the first sound data and supplies the generated sound signal to the amplifier, and further, outputting sound using the first sound data when the body is in a power-on state, and the second system configured to operate independently from the first system, and including a semiconductor memory storing a non-compression format second sound data and a digital-to-analog converter, which converts the second sound data into an analog sound signal and supplies the converted analog sound signal into the amplifier, and further, outputting sound using the second sound data when the body is in a power-off state.
