Abstract: Provided is an information processing apparatus including: a power supply control portion that performs control of a power supply; a detection signal emitting portion that, when a connection of an external power source is detected in an operation stand-by state in which power consumption is suppressed and an operation is on stand-by, emits a detection signal only for a certain time period, in accordance with the detection; and a power supply portion that supplies power to the power supply control portion based on the detection signal emitted by the detection signal emitting portion and also stops the power supply to the power supply control portion after a certain time period elapses from the connection in the operation stand-by state.

Abstract: Disclosed herein is an information processing apparatus including a storage section for storing an AC adapter capacity identification information with which a rated power capacity of an AC adapter which can supply power to the apparatus can be identified, a first outputting section for outputting the above mentioned AC adapter capacity identification information, a setting section for setting a threshold value with which control of power consumption of the apparatus is to be started based on the output AC adapter capacity identification information, a detection section for detecting the power consumption, and a control section for controlling such that when the detected power consumption exceeds the threshold value, the power consumption may become equal to or lower than the threshold value.

Abstract: A battery pack includes: an obtaining unit for obtaining computation information for calculating a charge current including temperature information of a battery; a computation unit for computing a charge current for the battery based on the computation information; and a notification unit for notifying a computer of the charge current computed by the computation unit. The notification unit uses a dedicated command to notify the computer of the charge current. The battery pack includes: a storage unit for storing therein a first threshold value and a second threshold value relating to the temperature information, and the computation unit may compute the optimal charge current depending on which of ranges divided by the first threshold value and the second threshold value the temperature information belongs to.
