Abstract: PROBLEM TO BE SOLVED: To suppress power consumption of a computer (PC) within AC power supply adapter capacity. SOLUTION: The power consumption of a PC provided with a base load consisting of plural components and a CPU including operation modes of a slot ring and clock down is controlled. The actual power consumption 103 of the CPU in a certain operation mode fluctuates relatively vehemently in the maximum power consumption range of the CPU. The fluctuation of the actual power consumption of the base load is moderate. The predictive maximum power consumption Pmax of the PC is obtained from the actual power consumption of the base load and the maximum of power consumption in the current operation mode of the CPU. Reference powers 121, 123 and 125 are set as objects to be compared with the Pmax to change from a certain operation mode to another operation mode. When the Pmax exceeds the reference power, the operation mode of the CPU is changed to control the actual power consumption of the PC.

Abstract: PROBLEM TO BE SOLVED: To prevent the shutdown of a body even if a battery is removed during the refreshing of the battery. SOLUTION: Electrical machinery and an apparatus comprise an AC adapter 51, a battery 52 for carrying out charging/discharging to supply electric power, an ACDC enable circuit 61 for changing the stop/start of electric power supply to a body from the AC adapter 51, a charger utilization circuit 62 for storing the electric power at an output capacitor (Cout) of a charger 60 while the electric power supply from the AC adapter 51 is stopped, and a battery connection confirmation circuit 63 for detecting that the battery 52 has been removed. When it is recognized that the battery 52 is removed while the electric power supply from the AC adapter 51 is stopped and the electric power is supplied to the body from the battery 52 by the battery connection confirmation circuit 63, power starts to be supplied to the body from the AC adapter 51 by the ACDC enable circuit 61 while the electric power stored in the output capacitor (Cout) is supplied to the body.

Abstract: PROBLEM TO BE SOLVED: To take electric power consumption by a micro-current not detected by a conventional circuit into account without expensing any special cost, and to reduce an error of a capacity data as a result thereof. SOLUTION: A capacity is accurately calculated in a low electric power consumption mode and the error of the found capacity data is reduced, by calculating the capacity data in the low electric power consumption mode when a software is turned off, not based on capacity calculation based on a current value measured by a current measuring circuit provided in a battery itself, but based on the capacity data found by multiplying a preliminarily found consumed current value in the low power consumption mode by a time when the mode continues and a voltage, or based on the capacity data found by multiplying the preliminarily found consumed current value in the low power consumption mode by the time when the mode continues.
