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.

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:
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.

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.
摘要:
An electronic apparatus according to the invention can be powered by a fuel cell unit and secondary battery unit. Power supply management utility executed by a CPU displays the states of use of the fuel cell unit and secondary battery unit. If a predetermined operation is performed in response to the displayed states, using a pointing device, the power supply management utility permits various types of setting related to the use of the fuel cell unit and secondary battery unit to be performed.

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:
A fuel cell unit according to the present invention includes a connection section used for establishing connection with an external device; fuel cells for generating power to be supplied to the external device through the connection section; a setting switch settable to power generation permission setting for permitting power generation using the fuel cells; and a control section capable of controlling the power generation using the fuel cells, when the setting switch is set to power generation permission setting. The above-described arrangements allow a simple operation for automatically executing the start/stop sequence of power generation in the fuel cell unit in operative association with the start/stop of the external device.
摘要:
A fuel cell unit according to the invention, includes a connection portion used for establishing the connection with an external apparatus, a fuel cell for generating power to be supplied to the external apparatus via the connection portion; auxiliary sections for feeding air and fuel to the fuel cell, and a controller for controlling the auxiliary sections and performing refresh processing to improve power generation efficiency of the power generator. The fuel cell unit can avoid reduction in power generation capability and maintain a constant power generation capability.
