1. A printing apparatus comprising:
- a printer;
a controller that includes at least a processor, a memory, and a sleep recovery circuit, and controls the printer; and
a sleep recovery button that receives a user operation and causes a signal to be detected by the sleep recovery circuit in response to receiving the user operation,wherein, when an auto sleep timer value becomes zero, the controller shifts the printing apparatus to a power saving mode in which power is not supplied to the printer and the processor, but power is supplied to the sleep recovery circuit,wherein, when the sleep recovery button receives the user operation, the sleep recovery circuit detects the signal and causes power to be supplied to the processor and the memory, thereby causing the controller to;
in a case where an operation time of the sleep recovery button is shorter than a threshold value, shift the printing apparatus from the power saving mode to a first power mode in which power is not supplied to the printer, and reset the auto sleep timer value to a default value; and
in a case where the operation time of the sleep recovery button is longer than a threshold value, shift the printing apparatus from the power saving mode to a second power mode in which power is supplied to the printer, and reset the auto sleep timer value to an extended value different from the default value, according to the operation time of the sleep recovery button, andwherein the operation time of the sleep recovery button includes a depression time of the sleep recovery button.

Abstract
An information processing apparatus capable of changing a state of power supply to respective parts of the apparatus with less user operation. When a sleep recovery button is depressed in a power saving mode, a button depression time is measured, and whether a length of the measure depression time exceeds a threshold value is determined. If the depression time exceeds the threshold value, a normal power mode is selected as power mode after transition. If the depression time does not exceed the threshold value, another power saving mode is selected as power mode after transition. According to the selected power mode, a state of power supply to respective parts of the apparatus is changed.

7. A control method of controlling a printing apparatus that includes a printer and a sleep recovery button that receives a user operation, the control method comprising:
-
when an auto sleep timer value becomes zero, shifting the printing apparatus to a power saving mode in which power is not supplied to the printer and a processor, but power is supplied to a sleep recovery circuit; causing a signal to be detected by the sleep recovery circuit in response to receiving the user operation; causing power to be supplied to the processor in response to detecting the signal; in a case where an operation time of the sleep recovery button is shorter than a threshold value, shifting the printing apparatus from the power saving mode to a first power mode in which power is not supplied to the printer, and resetting the auto sleep timer value to a default value; and in a case where the operation time of the sleep recovery button is longer than a threshold value, shifting the printing apparatus from the power saving mode to a second power mode in which power is supplied to the printer, and resetting the auto sleep timer value to an extended value different from the default value, according to the operation time of the sleep recovery button, wherein the operation time of the sleep recovery button includes a depression time of the sleep recovery button.
