An information processing apparatus includes a storage unit, a first starter unit that starts up a system program, a second starter unit that starts up an updating program for updating the system program, and a control unit that control to, in a case where the updating program has not been started up normally, start up a recovery program, and output a message prompting a user to attach a storage medium storing a snapshot image of the storage unit including the updating program for updating the system program.

Start-up processing for information processing apparatus and method, and storage medium

An image forming apparatus having a verification function of verifying a predetermined program includes a controller configured to execute the verified predetermined program, a predetermined unit, and a power supply configured to supply power to the controller and the predetermined unit, wherein the power supply is configured to start supplying power to the predetermined unit before the verifying of the predetermined program is completed, and if the predetermined program is confirmed not to be authentic by the verifying, stop supplying power to the predetermined unit.

Image forming apparatus and method for controlling image forming apparatus

An image forming apparatus equipped with a sleep function and for forming an image using an image forming unit and a control method thereof. The image forming apparatus includes a control unit that controls the image forming unit. When a job is received in a sleep state, a port number of the received job is discriminated, whether or not to perform initialization processing of the image forming unit is determined based on the discriminated port number, and in a case that it is determined that initialization processing of the image forming unit is necessary, initialization processing of the image forming unit is started and thereafter the control unit is controlled to start processing of the job.

Image forming apparatus with controlled activation based on port number and control method thereof

The present invention relates to a job processing apparatus including an instruction unit configured to provide an instruction to shift a power supply to an OFF state, a setting unit configured to variably set a suspended time for shifting from a suspended state to the OFF state based on a threshold of the number of rewritable times calculated by a calculation unit and a number of writing times, and a control unit configured to shift the power supply to the OFF state after the suspended time set by the setting unit has lapsed.

Apparatus and method for extending life of a storage unit by delaying transitioning to a hibernation state for a predetermined time calculated based on a number of writing times of the storage unit

An image forming apparatus capable of communicating with a server apparatus, includes a receiving unit configured to receive a packet from the server apparatus, a determining unit configured to determine whether a packet received by the receiving unit is a specific packet, a power supply control unit which, when the determining unit determines that a packet received by the receiving unit is the specific packet, brings the image forming apparatus into a first power condition which enables the image forming apparatus to start quickly using data stored in a volatile memory, and a start control unit configured to start the image forming apparatus quickly using data stored in the volatile memory.

Image forming apparatus, control method of image forming apparatus and storage medium

The invention relates to an information processing apparatus which performs mirroring for synchronizing storage contents of a first storage unit and a second storage unit. If mirroring is valid when the information processing apparatus is started, the information processing apparatus detects a storage unit attached to itself. If a detection result indicates that no storage unit has been detected or one storage unit has been detected, the information processing apparatus displays, on a display unit, a connection acknowledgement screen for the storage unit which has not been detected. If the detection result indicates that two storage units have been detected, activation processing is executed for the information processing apparatus.

Information processing apparatus, control method therefor and storage medium

An information processing apparatus configured to have a first power mode and a second power mode having lower power consumption than that of the first power mode includes a detection unit configured to detect brightness around the information processing apparatus, a setting unit configured to set a time period for shifting the information processing apparatus to the second power mode, and a control unit configured to, if the brightness detected by the detection unit is lower than a threshold, when a time is within the time period set by the setting unit, shift the information processing apparatus to the second power mode, and, when the time is not within the time period set by the setting unit, not to shift the information processing apparatus to the second power mode.

Setting power saving modes based on ambient light and user set time periods

An image forming apparatus includes a communication unit configured to communicate with a server apparatus, a power supply control unit configured to repeat power supply to the communication unit, and an inquiry unit configured to make an inquiry to the server apparatus about whether to turn on a second power supply unit that energizes a controller that controls the image forming apparatus, each time the communication unit becomes communicable with the server apparatus by the power supply control unit, wherein the power supply control unit repeats power supply to the communication unit for each of a plurality of predetermined time periods, until receiving a response to turn on the power of the second power supply unit from the server apparatus in response to the inquiry by the inquiry unit.

Image forming apparatus, control method for image forming apparatus, and storage medium for performing power-saving control

An image forming apparatus according to the present invention is capable of connecting a removable storage device that stores operation data controlling an operation of the image forming apparatus. When a shutdown instruction of the image forming apparatus is received from a user, it is determined whether or not it is necessary to execute an operation using the operation data stored in the removable storage device. In a case that it is determined that it is necessary to execute an operation using the operation data, the image forming apparatus stores the operation data stored in the removable storage device into an incorporated non-volatile storage unit and shots down, and then restart. After the restart is performed, it is controlled so that an operation using the operation data that has been stored in the incorporated non-volatile storage unit is executed.
