A power supply controller measures electrical power consumed by information processing apparatus. An embedded controller passes the data to power management utility software each time a specified length of time is elapsed. The utility software accumulates a difference as found between this consumed power level and a predetermined reference value. The utility software shifts the information processing apparatus into its power-save modes when the accumulated value becomes larger than the predetermined value.

Each buffer circuit in a clock driver is enabled/disabled in accordance with clock drive control information set in a clock drive control register. Since the clock drive control information set in the register is programmable, the clock signal lines of a plurality of PCI devices can be selectively driven. Therefore, clock supply to unused PCI devices can be stopped, so that wasteful power consumption can be reduced.

In a computer system constituted by a portable computer and a deskstation used to expand the function of the portable computer, the portable computer has a communication connector used for communication with the deskstation, in addition to a connector for connecting a system bus in the portable computer to the deskstation. Similarly, the deskstation also has a communication connector. When the portable computer is set at a predetermined position of the deskstation, these connectors are connected to each other before the system bus is connected to an expansion device of the deskstation. By using the communication connectors to perform communication between the portable computer and the deskstation, disconnection between the system bus and an expansion connector or forced suspend processing of the portable computer is executed before the portable computer in a power ON state is mounted in the deskstation. In addition, a lock mechanism is provided to lock the portable computer with the deskstation. The lock mechanism is operated/released by registering/deleting a password. Even when a power supply unit having a plurality of power supply outlets is externally provided to the deskstation, processing for sequentially enabling the power supply outlets is executed. Temperature control in the portable computer is also executed.

A fuel cell unit for supplying electric power to an electronic apparatus includes a DMFC that generates electric power using methanol as fuel. A microcomputer examines whether or not the fuel cell unit has been installed in the electronic apparatus. When the fuel cell unit has been installed in the electronic apparatus, the microcomputer visually informs the user, using LEDs, of the operating state of the DMFC detected by various sensors, including an installation and removal sensor, a liquid level sensor, a temperature sensor, and an acceleration sensor.

In a fuel cell unit, a control method therefor, and an information processing apparatus, a determination is made as to whether or not elapsed time from the last power generation until the present power generation has reached a predetermined time. When it is determined that the elapsed time has reached the predetermined time, setup processing for hydrating a solid polymer electrolyte membrane of a fuel cell is performed.

摘要:
An insulation layer is formed on a ground layer. The insulation layer includes first and second regions for forming wiring layers. The impedance of a wiring layer formed on the second region is lower than that of a wiring layer formed on the first region. A signal line pattern is formed on the wiring layer on the first region of the insulation layer. A power supply plane is formed on the wiring layer on the second region of the insulation layer in order to feed power to the signal line pattern through a termination resistor connected to the signal line pattern.

A computer main body has a system bus. The system bus is connected to a PCI-DS bridge. A docking station has a plurality of expansion devices for expanding the functions of the computer main body. The computer main body is attached to the docking station by means of the DS-PCI/ISA bridge of the docking station and the PCI-DS bridge of the computer main body, while the expansion devices of the docking station are separated from the bus of the computer main body. The computer main body outputs to the docking station an instruction for starting power supply, after having been attached. After switching on of the docking station has been detected, gates in the bus sides of the DS-PCI/ISA bridge and the PCI-DS bridge are switched ON.
