Claim:
1. An apparatus which requires power supply for operation of the apparatus, the apparatus comprising: a memory which stores monitoring settings; and a control board which determines a state of the power supply using the monitoring settings stored in the memory, wherein, when power is supplied from a first power supply including an AC cord to a main body of the apparatus in which the first power supply and a second power supply including an AC cord can be mounted, power being supplied from the second power supply to the main body of the apparatus, a state of the power supplied from the second power supply being monitored, the control board makes a first determination as to whether or not the second power supply is mounted in the main body of the apparatus based on a power-supply mount-state notification signal which is output from the second power supply and indicates whether or not the second power supply is mounted in the main body of the apparatus, and if the result of the first determination indicates that the second power supply is mounted in the main body of the apparatus, makes a second determination as to whether or not the power is supplied from the AC cord of the second power supply based on an AC-supply state notification signal which is output from the second power supply and indicates whether or not the power is supplied from the AC cord of the second power supply, if the result of the second determination indicates that the power is not supplied from the AC cord of the second power supply, the control board notifies a user of the fact that the second power supply is mounted in the main body of the apparatus and the power is not supplied from the AC cord of the second power supply.
