Description of the Invention: [Technical Field] The present invention relates to a driving circuit in a computer, and more particularly to a driving circuit for indicating a working state of a computer by a status indicator of a moving computer. [Prior technology] π in the use of the computer, the computer has a normal working state and sleepy sorrow 'If any computer has a power saving mode 't computer _ a period of time after no use, 'automatically enters a dormant state, or people will The computer is set to work or hibernate. ^ Display the different working status of the computer, usually use the status indicator, the display of the indicator is different in different modes. Some are on the motherboard of the computer or display: sneak on the two status indicators, one indicator is constantly lit when the computer is working normally ^ 'When the computer is hibernating, the other _ indicator is in the computer: work It annihilates when the state is on, and it illuminates continuously while the computer is asleep. There are also computers: only - a status indicator 'This indicator continues in the normal state of the computer ^ flashes when the computer is sleeping, such as the mainland China G3236782. The nickname is "electrical state indicator" patent That is, a status indicator light is used, which is controlled by the control circuit. The control circuit is composed of a single-chip microcomputer, and the response is: the signal of the working and the sleep state, by the process of curing in the single-chip chip = different control signals, Control the indicator light to change with the state of the computer. • The control circuit used by the status indicator must be controlled by a single-chip microcomputer. The use of the control circuit is complicated. The control flow must be designed and the status indicator 坆-the cost of the auxiliary function circuit on the computer. Greatly increased, it is not necessary. And the trend of the η brain status indicator is to set the indication of two different colors. When the computer 2 can be improved, the space for displaying various states is reserved. Therefore, a simple driving circuit is required, and the state with two indicators is not indicated. 〇 〇 6l6 [Summary] The purpose is to provide a simple design for the driving state should be made to the state of the computer for different states of the computer to the tree state indicator light drive circuit, set in the computer, the computer state signal output埠 and a sleep state signal output 埠, the shape
