Abstract:
An information processing apparatus includes a first unit and a second unit supplied with power that can be interrupted individually, a power supply switch configured to be operated by a user, to turn off a power supply of the information processing apparatus, a controller configured to perform shutdown processing of the information processing apparatus thereby interrupting supply of power to the first unit and the second unit, upon turning off of the power supply switch, a first timer unit configured to interrupt the supply of the power to the first unit, after a lapse of a first predetermined time after turning off the power supply switch, and a second timer unit configured to interrupt the supply of power to the second unit, after a lapse of a second predetermined time after turning off the power supply switch. The second predetermined time is longer than the first predetermined time.
