Embodiment Construction

[0013] Please refer to figure 2 , the present invention has the computer system of restart control circuit 10, and this computer system comprises a power supply 1, a motherboard 6 and a restart control circuit 10, and this restart control circuit 10 is arranged between computer power supply 1 and motherboard 6.

[0014] The power supply 1 includes a system power output terminal 2 and a standby power output terminal 3 . The power supply 1 is an ATX power supply used in today's computer systems. The characteristic of this power supply is that the ATX power supply itself does not completely cut off the power when it is turned off, but maintains a relatively weak current. At the same time, it uses this current to add a power management function called Stand-By, which has a standby voltage of +5V SB , output from the standby power supply output terminal 3. The power supply terminal (not shown) of the restart control circuit 10 is connected to the standby power supply output term...

Abstract

The computer system with re-starting control circuit includes one power source, one system unit board and one re-starting control circuit. The power source includes one system power source output and one ready power source output. The system unit board includes one power source signal receiving end to receive start triggering signal. The re-starting control circuit set between the power source of the computer and the system unit board includes one input end connected to the system power source output of the power source, one power source end connected to the ready power source output of the power source, and one output end connected to the power source signal receiving end of the system unit board. The re-starting control circuit operates on the voltage characteristic of computer power source in power on-off state, charges slowly after the computer is turned off for delay re-starting and discharges fast after the computer is turned on for feedback control to complete starting process.

Description

【Technical field】 [0001] The invention relates to a computer system, in particular to a computer system which has a restart control circuit and can automatically restart after a shutdown. 【Background technique】 [0002] In the reliability verification stage of computer motherboard research and development, it is necessary to place the motherboard in the computer system and perform a cycle test of "start-delay-shutdown-delay-start". Generally, about 1,000 tests are required. After starting up, the process of shutting down can be controlled by computer software to realize automatic shutting down; while starting up after shutting down, you need to manually press the button on the front panel of the computer to start the power supply and start up. [0003] Existing computer boot operating systems such as figure 1 As shown, when the button (POWER BUTTON) on the front panel of the computer is pressed, the power-on trigger signal, that is, the PS_SWITCH signal is directly sent to ...
