摘要:
A power supply circuit for a computer system includes an AC adapter designed to be connectable to the computer system and supplying power to the system, a main battery and a second battery that are designed to be connectable to the computer system and get charged with power from the AC adapter and then discharge it to supply power to the system, a charger that is a charging circuit for the main battery and/or the second battery while the main battery and/or the second battery is connected to the AC adapter with the computer system powered off, and a gate array circuit for turning off the power supply to an embedded controller.

A method and system are provided for thermal management of a portable computing apparatus. Accelerometers are provided to detect changes in attitude, and temperature sensors are provided to detect changes in temperature. A fan is used to cool the internal temperature of the electronic components of the computer. In response to lift of the computer from a stationary surface, the computer may transition to an alternative state of operation. The transition may include the change of the speed of the fan and/or adjustment of the processor clock.

A manufacturing method for manufacturing ceramic electronic components, includes steps of forming a stack body by stacking ceramic green sheets and conductive layers on top of each other, punching a frame into the stack body and holding the frame in the stack body, locating a pressing force applying member inside the frame and, while the frame is held in the stack body, applying a pressing force to a portion of the stack body located inside the frame by causing the pressing force applying member located inside the frame to press against the portion of the stack body located inside the frame, to thereby form a high-density structure inside the frame while preventing the high-density structure from deforming outwardly beyond the frame. The stack body can be heated to reduce the required pressing force, and an elastic member may be provided to make the pressing force uniform.

The invention realizes the execution of a predetermined process just before the turn-off of the power of a computer, without incurring increase in the load.A shutdown reset logic 52 is provided between a power management unit 68 on a core chip and a power circuit 54. The logic 52 is enabled just before the system is shut down, and it interrupts the inputting of a power-off signal −SUSC output from the power management unit 68 to the power circuit 54, inputs a signal LAST#PWG#PIIX4 representing a faulty power state to the power management unit 68 to cause a hardware reset, and inputs a signal −PERSW#PIIX4 representing the turn-on of a power switch 92. This causes the POST to be started, and the POST turns off the power of the system after enabling the WOL function of the network adapter.

In general, the present invention provides a computer apparatus, power supply control method and program for reducing the standby power requirements in a computer supporting a wake-up function. The present invention reduces standby power requirements on power off by three types of control: a wake-up function being set by a user, existence of a device actually capable of realizing the wake-up function, and supplying the power from the auxiliary source only to the device capable of realizing the wake-up function.

A computer and a method for enabling remote communication to a computer operating in a power-saving mode in which one or more one power sources to internal devices are disabled. The computer is equipped with a power management control circuit which is responsive to a first signal indicating that a device used to receive remote communication is to receive power while operating in a power-saving mode. In the event that a remote communications is detected which is targeted for the computer, a second signal is asserted by the remote communications device. The power management control circuit responds by exiting the power-saving mode and restoring power to the disabled power source to enable the computer to process the incoming communication. The remote communication may be through a wireless source such as a radio frequency channel or through a fixed wire such as a telephone network or LAN. Other aspects of the invention enable communication through an option card installed in a option slot or a notebooks docking station such as a radio device, modem, or LAN adapter.
