Embodiment Construction

[0023] In order to make the object, technical solution, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0024] see figure 1 as shown, figure 1 It is an overall framework diagram of the present invention. The main board status signal is sent to the computer keyboard interface, and the keyboard control circuit judges the operating status of the computer according to the main board signal, and sends different key codes. The different key codes refer to two or more than two sets of key codes. Therefore the present invention mainly relates to the modification of mainboard and keyboard two parts.

[0025] The state of the computer can be mainly divided into six states: S0, S1, S2, S3, S4, and S5. From the user's point of view, it is the state of S3 and S4 / S5 that is easy to confuse. Because in general, in terms of these two states, the former is mainly that...

Abstract

The status signal SLP_S3#, SLP_S5# of the computer main board through the vacant end of the keyboard interface are leaded to the keyboard. Based on the status of the computer, the keyboard control circuit set different key code. The keyboard interface is PS / 2 interface. The status signal SLP_S3#, SLP_S5# of the computer main board through the pin 2 end and the pin 6 end are leaded to the keyboard. By using the status of computer as the relevant condition, the invented keyboard can send different key code automatically so as to expand applications of computers.

Description

technical field [0001] The invention belongs to the field of computer applications, and in particular relates to a method for starting functions of a computer motherboard and a keyboard according to the state of the computer. Background technique [0002] The computer keyboard is an important standard input device of the computer. Most of the operations of the computer are completed by the keyboard, and various instructions, programs, data, etc. can be input to the computer through the keyboard. [0003] The basic working principle of the keyboard is to monitor the keys in real time and send the key information to the computer. In the interior of the keyboard, there are key scanning circuits for locating key positions, coding circuits for generating pressed key codes, and interface circuits for sending generated codes to computers, etc. These circuits are collectively referred to as keyboard control circuits. According to the working principle of the keyboard, computer keyb...
