摘要:
Dedicated registers are arranged in a status LCD control gate array connected to a system bus, and the dedicated registers or register group and a keyboard controller are connected through a keyboard interface bus. The keyboard controller has two ports for communicating with a CPU. The keyboard controller transfers existing commands released to an application program or the like and transmits normal key data through the system bus. The keyboard controller transmits hot key data and transfers a command for realizing any other special function through the keyboard interface bus and the dedicated registers.
摘要:
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.

摘要:
An electronic apparatus comprises a circuit, such as a semiconductor circuit, a temperature detection unit provided in the circuit, and a controlling unit. The temperature detection unit detects a temperature of the circuit and outputs a signal outside of the circuit when the detected temperature exceeds a threshold. The controlling unit powers off the electronic apparatus in accordance with the signal.

A fuel cell unit according to the present invention is connectable to an external apparatus and includes a fuel cell generating an electric power, an auxiliary device feeding a fuel and air to the fuel cell, and a controller controlling power generation performed using the fuel cell. After receiving an electric power supplied from the external apparatus, the controller supplies an electric power supplied from the external apparatus to the auxiliary device.
摘要:
A computer system is provided has a computer main body and an expansion unit to be attached to and detached from the computer main body. Power is input to the computer system in accordance with a plurality of factors. A power supply controller determines which factor has caused power-ON for the computer system, and writes the result of this determination into a power-ON factor register. BIOS reads the content stored in the power-ON factor register and executes processing in accordance with power-ON factors. Before the computer system is switched on, the power supply controller determines the connection, type and state of the expansion unit and writes the result of this into the state register. BIOS executes error processing, etc., in accordance with the content of the state register.

摘要:
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:
The power supply controller serves to distribute electric power to each part of the electronic apparatus for operation, and the electric power can be fed from the AC power source, the fuel cell unit and the secondary battery unit. The power supply controller transmits the data signal indicating from which of the AC power source, the fuel cell unit and the secondary battery unit, the electricity is fed, to the CPU via the built-in register. The CPU displays the use status of the AC power source, the fuel cell unit and the secondary battery unit on the LCD via the display controller.
