Abstract

PURPOSE:To decrease the danger of a misoperation of a user by constituting the system so that as for a keyboard input in a non-display state, only a migration to a display state of a display device is executed, and it does not become an input to an application program. CONSTITUTION:The system is provided with a keyboard input device C, a display device D, an arithmetic processor A, and a main storage device B, and when the display device D is in a display state, a keyboard input is read out by an operating system, and transmitted to an application program. When the display device D is in a non-display state, the keyboard input is read out by the operating system and switches the display device D to a display state. Also, the input in this case is rejected in the inside of the operating system, and not delivered to the application program. In such a way, the system which scarcely causes a misoperation can be obtained.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to computer systems.

Problem to be solved by the invention Ml However, in conventional computer systems, keyboard input when the display device is in a non-display state, that is, when the state of the computer system is unknown, becomes input to the application program. , there was a risk of erroneous operation.

Therefore, in the present invention, in response to keyboard input in the non-display state, only the display device is shifted to the display state, and
The purpose of this system is to provide users with an easy-to-use computer system with less risk of erroneous operation by creating a system that does not provide input to application programs.

[Prior Art] [Means for Solving the Problems] A computer system of the present invention includes a keyboard input device, a display device, an arithmetic processing device, and a main storage device, and when the display device is in a non-display state, , characterized in that input to the keyboard input device only causes the display device to enter a display state.

Hereinafter, the details of the present invention will be shown by examples.

When the display device is in the display state, keyboard inputs are read by the operating system and passed on to the application program.

When the display is in the non-display state, keyboard inputs are read by the operating system to switch the display to the display state. Further, the input at this time is discarded within the operating system and is not passed to the application program.

Embodiment FIG. 1 shows a block diagram of a computer system based on the present invention. Arithmetic processing unit A processes information based on information in main memory B and input from keyboard C, and outputs the results to a display device. Further, the processing unit A switches the display device to a non-display state as necessary.

In this system, there are two types of programs executed by the arithmetic processing unit: an operating system and an application.

[Effects of the Invention] As described above, according to the present invention, it is possible to realize a computer system in which recovery from a non-display state is performed by input from a user, and a system with fewer erroneous operations can be realized.

Claims (1)

[Claims] It has a keyboard input device, a display device, an arithmetic processing unit, and a main storage device, and when the display device is in a non-display state, by inputting to the keyboard input device, the display device is brought out of the non-display state. A computer system characterized by only transitioning to a display state.
