20090207423 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - In an information processing apparatus which incorporates a plurality of arithmetic units and a plurality of storage units, power consumption in a power saving mode is reduced, and a return time required to return from the power saving mode to a normal power mode is shortened. With this invention, in an information processing method in an information processing apparatus which incorporates a plurality of CPUs and a plurality of RAMs, when a condition required to transit to the power saving mode is satisfied, each CPU stores information associated with an operation state of an active program in one RAM, and turns off the power supply to devices except for the one RAM. | 08-20-2009 |
20120262751 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF - 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. | 10-18-2012 |
20120268790 | IMAGE FORMING APPARATUS AND METHOD OF CONTROLLING THE APPARATUS - 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. | 10-25-2012 |
20120290772 | STORAGE CONTROL APPARATUS FOR CONTROLLING DATA WRITING AND DELETION TO AND FROM SEMICONDUCTOR STORAGE DEVICE, AND CONTROL METHOD AND STORAGE MEDIUM THEREFOR - A storage control apparatus capable of properly deleting data dispersedly stored in a semiconductor storage device with wear leveling. The storage control apparatus converts an address given with a write instruction, among addresses of the semiconductor storage device, into another address, holds address conversion information that associates the before- and after-conversion addresses with each other, and controls the semiconductor storage device to write data into the after-conversion address. When a delete instruction is given, the storage control apparatus controls the semiconductor storage device in accordance with the address conversion information to delete data stored in an after-conversion address associated with an address given with the delete instruction. | 11-15-2012 |
20120307285 | IMAGE FORMING APPARATUS, CONTROL METHOD OF IMAGE FORMING APPARATUS AND STORAGE MEDIUM - 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. | 12-06-2012 |
20130050752 | IMAGE FORMING APPARATUS, CONTROL METHOD FOR IMAGE FORMING APPARATUS, AND STORAGE MEDIUM FOR PEFORMING POWER-SAVING CONTROL - 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. | 02-28-2013 |
20130145109 | INFORMATION PROCESSING APPARATUS, CONTROL METHOD THEREFOR 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. | 06-06-2013 |
20130258380 | IMAGE FORMING APPARATUS ALLOWING REMOTE START, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM STORING CONTROL PROGRAM THEREFOR - An image forming apparatus that is capable of reducing power consumption when a main power is OFF and of performing remote start without using an exclusive circuit. A power control unit supplies power to a main control unit and a communication module that communicates with an external apparatus. A first-communication-module-control unit controls the communication module to operate in a first operational mode in which the main control unit does not operate in a normal mode. A supply instruction unit instructs the power control unit to supply power for operating the main control unit in the normal mode, when the external apparatus instructs to start the image forming apparatus and the communication module operates in the first operational mode. A second-communication-module-control unit controls the communication module to operate in a second operational mode in which the main control unit operates in the normal mode. | 10-03-2013 |
20140143566 | ELECTRONIC APPARATUS OPERATABLE IN POWER SAVING MODE, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM STORING CONTROL PROGRAM THEREFOR - An electronic apparatus that is capable of preventing overcharge and overdischarge of a battery. The electronic apparatus is operatable in a normal mode and a first power saving mode with less power consumption. A battery supplies electric power until battery residual capacity reaches a first threshold in the first power saving mode. A charging unit charges the battery in the normal mode. A control unit controls, in a case that the battery residual capacity is smaller than a second threshold larger than the first threshold when transition to the first power saving mode is made, so as to charge the battery until the battery residual capacity reaches the second threshold, and make a transition to the first power saving mode. | 05-22-2014 |
20140281631 | ELECTRONIC DEVICE, POWER CONTROL METHOD AND STORAGE MEDIUM STORING PROGRAM THEREOF - In an electronic device, a first sensor detects a detection target on a first region.
