  • Publication number: 20220094805
    Abstract: An image forming apparatus capable of switching power state between a first power state and a second power state, which is lower in power than the first power state, shifts from the second power state to the first power state. In a case where the image forming apparatus shifts to the second power state in response to a current time reaching a set time, the image forming apparatus is controlled not to shift from the second power state to the first power state in response to an object approaching the image forming apparatus being detected.

  • Patent number: 10999462
    Abstract: An information processing apparatus including a push switch turns off a power supply state of a main body and starts shutdown processing when a first user's operation is performed on the push switch in a normal state of the apparatus. When a second user's operation is performed on the push switch during the shutdown processing, the power supply state of the main body is switched between on and off. If the power supply state of the main body is the on state when the shutdown processing is completed, first processing for restarting the main body is performed, and if the power supply state of the main body is the off state when the shutdown processing is completed, second processing for stopping power supply to the main body is performed.

  • Publication number: 20200177756
    Abstract: An information processing apparatus which is capable of preventing unintended power abnormality data arising from remaining electronic charge being written into a nonvolatile memory. The nonvolatile memory stores information indicating that an output voltage of the power supply device has become equal to or lower than a threshold value. Power is controlled to be supplied from a power supply device to a processor in accordance with an operation on a power switch received in a state where no power was supplied to the processor, and power is controlled to be supplied from the power supply device to the processor in accordance with the information stored in the nonvolatile memory. Writing of the information into the nonvolatile memory is enabled in accordance with input of a predetermined signal output from the processor to which the power is supplied.
