摘要： An energization range of a laptop PC is controlled for safety component replacement. An EC can communicate with a battery unit to control a FET of the battery unit. In a power-off state, a PWC receives electricity from the battery unit or an AC/DC adapter. In the power-off state, a system of the EC stops. When a housing cover of the laptop PC is opened, a cover switch turns ON. When a logic circuit detects the operation of the cover switch, the PWC controls a DC/DC converter group to activate the system. The EC receiving electricity turns the FET OFF. Then the PWC turns the FET OFF.

摘要： An apparatus for controlling power efficiency of an information processing device is disclosed. The apparatus includes a voltage converter that converts an input voltage into a predetermined output voltage, an information processing device that consumes power supplied by the voltage converter, a battery pack that is charged using power supplied at a predetermined charging voltage by the voltage converter, and a controller that determines the input voltage where the power supplied by the voltage converter exceeds power consumed by the information processing device and a difference between the input voltage and the predetermined charging voltage is minimized. A method and a system also perform various functions of the apparatus.

摘要： An information processing apparatus includes: a controller that outputs notification information based on input information; and a processor that executes system processing based on an operating system (OS) and operation of thermal control processing by control of a Basic Input Output System (BIOS) using the notification information output from the controller. The controller accepts an operation signal indicative of an operated key according to a user's operation on a keyboard; determines whether the operated key is of a specific combination of keys based on the accepted operation signal; upon making a determination that the operated key is of the specific combination of keys, outputs, to the processor, a result of the determination as the notification information; and without another key being pressed after the result of the determination is output from the controller, the processor executes the thermal control processing based on the result of the determination.
