The storage device is configured to store power-saving setup information, including at least one setup item relating to an operation affecting an amount of power consumed by the information processing apparatus. The processor is configured to (i) set a value of the at least one setup item, (ii) control operations based on a current setup value, (iii) acquire first setup information for automatically setting a value (first setup value) of the at least one setup item, (iv) compare the first setup value and the current setup value, and (v) automatically apply one of the first setup value and the current setup value to the at least one setup item based on a result of the comparison, the one of the first setup value and the current setup value having a higher power-saving effect.

Information processing apparatus and operation control method

According to one embodiment, an electronic apparatus includes: a presence determining module configured to determine at an interval whether a user is present based on image data output by a camera; a display power controller configured to turn on a display when the user is present and to turn off the display when the user is not present, based on a result of the presence determining module; and a detection interval controller configured to control the interval such that the interval is shorter when the display is off compared to when the display is on and the user is determined to be present.

Electronic apparatus, electronic apparatus controlling method, and computer program product

An electronic device includes: display controller; user presence determination module; user authentication module; and controller. The user presence determination module determines presence of a user based on image data received from the camera while dominating access to a camera. The user authentication module dominates access to the camera, if the display is put in a screen lock state and to perform a user authentication based on the image data. The controller turns off the display if the user present determination module determines that the user is absent and while the display has not been put in the screen lock state, and to cause the user presence determination module to release the access to the camera and to put the display in the screen lock state before turning on the display if it is determined after the display is turned off that the user is present.

Electronic device, electronic device controlling method, and computer program product

According to one embodiment, an information processing apparatus includes a storage device, a setup module, an operation control module, and a setup value control module. The storage device stores power-saving setup information including at least one setup item relating to an operation of the apparatus. The setup module sets up a value of the at least one setup item in accordance with a user operation. The setup value control module acquires first setup information including a first setup value corresponding to the at least one setup item, and applies a setup value with a higher power-saving effect, which is selected between the first setup value and a current setup value of the at least one setup item, to the at least one setup item.

According to one embodiment, an information processing apparatus includes an optical disc drive, a data processing module which executes data processing using the optical disc drive, and a power supply management module which manages supply of power to the optical disc drive. The data processing module interrogates the power supply management module about the optical disc drive at the time of activation, and waits until an operating system recognizes the optical disc drive when an instruction is received from the power supply management module in response to an interrogation. The instruction instructs to wait until the operating system recognizes the optical disc drive. The power supply management module shifts the optical disc drive to a power supply on state and returns the instruction to the data processing module, if the optical disc drive is in a power supply off state when the interrogation is received.

Information processing apparatus and operation control method of an information processing apparatus

According to an aspect of the present invention, there is provided an information processing apparatus that is operable in a first operation state and a second operation state, the apparatus including: a history storage unit configured to accumulate: a power usage reduction that is calculated based on a power usage difference between the first operation state and the second operation state; and an acquisition time at which the power usage reduction is acquired; an adding-up unit configured to add up values of the power usage reduction for a given period thereby calculating a power usage reduction amount; and an image generation unit configured to generate an image indicating a difference between the power usage reduction amount and a target value therefor and to display the image on a display device.

Information processing apparatus and power saving effect display method

According to one embodiment, an information processing apparatus includes a main body, an optical disc drive provided in the main body, and a drive management module provided in the main body. The optical disc drive is configured to output an eject signal to an outside in response to an operation of an eject button. The drive management module is configured to supply power to the optical disc drive when the eject signal is received from the optical disc drive which is in a power-off state, to determine, after supplying the power to the optical disc drive, whether the optical disc drive is in a ready state or not, and to send to a signal instructing opening of a tray of the optical disc drive when it is determined that the optical disc drive is in the ready state.

Information processing apparatus and drive control method

According to one embodiment, an information processing apparatus includes a main body, an optical disc drive provided in the main body, an acceleration sensor provided in the main body, and a drive management module provided in the main body. The optical disc drive is configured to output an eject signal to an outside in response to an operation of an eject button. The drive management module is configured to determine whether the main body is shaking or not by using the acceleration sensor when the eject signal is received from the optical disc drive which is in a power-off state, and to supply power to the optical disc drive and send to the optical disc drive a signal instructing opening of a tray of the optical disc drive, when the main body is not shaking.

According to one embodiment, an information processing apparatus having a power-saving function includes a monitoring module and a power-saving setting presenting module. The monitoring module monitors a usage pattern of the information processing apparatus, and stores log information indicative of the usage pattern in a storage device. The power-saving setting presenting module determines recommended values of power-saving parameters for specifying content of the power-saving function, based on the stored log information, and to display the determined recommended values.

Information processing apparatus and power-saving setting method

According to one embodiment, an information processing apparatus having a power-saving function includes a power-saving control module, a power consumption measuring module, a log accumulation module, and a log display module. The power-saving control module sets each of predetermined components in the information processing apparatus in either a normal operation state or a power-saving state, based on power-saving parameters corresponding to the predetermined components. The power consumption measuring module measures a total power amount consumed by the apparatus in a predetermined time period. The power-saving effect calculation module calculates a power-saving effect value indicative of a power amount reduced in the predetermined time period by the setting of the power-saving parameters. The log storing module stores information indicative of the total power amount and the power-saving effect value. The log display module displays cumulative values which are periodically accumulated the total power amounts and the power-saving effect values.
