Abstract
An image processing apparatus that is capable of being instructed to power off, by a power switch or a command from an external apparatus, and is capable of executing the restart thereof under appropriate conditions. When power-off is instructed, shutdown is started. Upon completion of the shutdown, if the power switch is on, and at the same time the power-off has been instructed by the power switch of the apparatus, the restart of the apparatus is executed, whereas upon completion of the shutdown, if the power-off has been instructed by a command from the external apparatus, the restart of the apparatus is not executed.
Claims7
An information processing apparatus which is able to communicate with an external apparatus, comprising:
- a power switch adapted to turn on or off power of the information processing apparatus;
- a reception unit adapted to receive a command for turning off the power of the information processing apparatus from the external apparatus;
- an execution unit adapted to execute shutdown of the information processing apparatus in response to turning off of the power switch or receiving of the command from the external apparatus;
- and
- a control unit adapted to control, in case that the execution unit executes shutdown of the information processing apparatus in response to turning off of the power switch, to restart the information processing apparatus when the power switch is on at completion of the shutdown of the information processing apparatus, and to turn off the power of the information processing apparatus when the power switch is off at completion of the shutdown of the information processing apparatus, and, in case that the execution unit executes shutdown of the information processing apparatus in response to receiving of the command from the external apparatus, to turn off the power of the information processing apparatus regardless of a state of the power switch at completion of the shutdown of the information processing apparatus.
A method for controlling an information processing apparatus connectable to an external apparatus, the information processing apparatus including a power switch for turning on or off power of the information processing apparatus,
- the method comprising:
- receiving a command for turning off the power of the information processing apparatus from the external apparatus;
- executing shutdown of the information processing apparatus in response to turning off of the power switch or receiving of the command from the external apparatus;
- and
- controlling, in case that the execution unit executes shutdown of the information processing apparatus in response to turning off of the power switch, to restart the information processing apparatus when the power switch is on at completion of the shutdown of the information processing apparatus, and to turn off the power of the information processing apparatus when the power switch is off at completion of the shutdown of the information processing apparatus, and, in case that the execution unit executes shutdown of the information processing apparatus in response to receiving of the command from the external apparatus, to turn off the power of the information processing apparatus regardless of a state of the power switch at completion of the shutdown of the information processing apparatus.
A non-transitory computer-readable storage medium having stored therein a program for causing a computer to implement a method for controlling an information processing apparatus connectable to an external apparatus, the information processing apparatus including a power switch for turning on or off power of the information processing apparatus,
- the method comprising:
- receiving a command for turning off the power of the information processing apparatus from the external apparatus;
- executing shutdown of the information processing apparatus in response to turning off of the power switch or receiving of the command from the external apparatus;
- and
- controlling, in case that the execution unit executes shutdown of the information processing apparatus in response to turning off of the power switch, to restart the information processing apparatus when the power switch is on at completion of the shutdown of the information processing apparatus, and to turn off the power of the information processing apparatus when the power switch is off at completion of the shutdown of the information processing apparatus, and, in case that the execution unit executes shutdown of the information processing apparatus in response to receiving of the command from the external apparatus, to turn off the power of the information processing apparatus regardless of a state of the power switch at completion of the shutdown of the information processing apparatus.
