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.

Information processing apparatus and power supply control circuit

A power switch and connector that are conventionally included in a body are formed in spaces created at the outer ends of the shafts of hinges other than the body and a display, whereby the body is thinned. Electronic device comprises a body, a display, and a hinge that joins the body and display so that they can be freely opened or closed. A power switch is formed at an end of the shaft of the hinge. Furthermore, the electronic device comprises the body, the display, and another hinge that joins the body and display so that they can be freely opened or closed. A port of a connector opens at an end of the shaft of the hinge.

Electronic device

Performing power saving control which can be inherited and standardized easily, and which keeps power devices from having to become larger is made possible. A current In flowing through an electrical path is detected as a voltage Vs by a current detection section, and is outputted as a voltage Vout by an amplifying section. When a level corresponding to the voltage Vout exceeds a limit level, a power limit detection section outputs a power limit detection signal. When a controller receives the power limit detection signal via a detection signal holding section, the controller outputs a throttle control command signal. When a chip set receives the throttle control command signal, the chip set initiates throttle control that lowers the clock frequency of a CPU. The present invention may be applied to laptop personal computers.
