Abstract: According to one embodiment, an electronic device includes a policy acquirer, a random number generator and a confirmation time determination processor. The policy acquirer acquires policy information indicating a common storage area storing an update program, and a time period in which presence or absence of the update program in the common storage area is to be confirmed. The random number generator generates a random number. The confirmation time determination processor creates a plurality of candidate times by dividing the time period by a predetermined time unit, and determines a confirmation time at which presence or absence of the update program is to be confirmed by selecting one of the plurality of candidate times using the random number.

Abstract: According to one embodiment, an electronic apparatus includes a hardware processor. The hardware processor executes first authentication processing and second authentication processing when the electronic apparatus is powered on or rebooted. The hardware processor executes the first authentication processing using first data stored in the nonvolatile storage region after executing the second authentication processing in a case of executing the second authentication processing when the electronic apparatus is powered on or rebooted. The hardware processor deletes the first data from the nonvolatile storage region when setting of not executing the second authentication processing upon the electronic apparatus is powered on or rebooted is made.

Abstract: According to one embodiment, an information processing apparatus includes an operation control module, a calculator, and a display processor. The operation control module is configured to set the information processing apparatus in a power-saving state, based on a power-saving setup value corresponding to at least one power-saving setup item. The power-saving setup value is set by a user. The calculator is configured to calculate a total score indicative of a degree by which the power-saving state contributes to power saving during a period from a score calculation start time point to a reference time point. The display processor is configured to display an image associated with the total score.

Abstract: According to one embodiment, information processor includes: setting module; processor; monitoring module; analyzer; and notification module. The setting module specifies first value as first power saving function. The processor controls modules in accordance with the first value. The monitoring module accumulates in storage device information indicating usage of the modules as log. The analyzer determine based on the log whether power saving is achieved by the first power saving function when the processor controls the modules in accordance with the first value. The notification module notifies a user to use a second power saving function when power saving by the first power saving function is not achieved. Here, the second power saving function is expected to provide a larger power saving effect than that of the first power saving function, and realizes power saving in accordance with the usage of the modules.

Abstract: 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.
