Claim Text:
1. A control circuitry used in a computing system, for enabling or disabling a standby module of a power supply, electrically coupled to two nodes of the standby module, comprising: a determination circuit, for judging a setting that whether the computing system being turned off requires a standby voltage; a transistor, a control end thereof is electrically coupled to the determination circuit, wherein when the determination circuit judges the setting that the computing system being turned off requires the standby voltage correspondingly, the determination circuit turns on the transistor, otherwise, the determination circuit turns off the transistor; and an optical coupler, electrically coupled to the transistor, wherein when the transistor is turned on, the optical coupler shorts the two nodes of the standby module to enable the standby module, and when the transistor is turned off, the optical coupler disconnects the two nodes of the standby module to disable the standby module.
