ABSTRACT:
A computer starter and starting method for an ATX computer system which provides a standby voltage when the computer system is shut down. The computer starter takes the standby signal as its power supply and includes a smart card interface, a clock generator, a non-volatile memory, a micro-controller and a power control circuit. The smart card interface generates an enable signal upon insertion of a smart card. The clock generator generates a reference clock in response to the enable signal. The non-volatile memory stores a computer identification signal. The micro-controller resets the smart card, reads a user identification signal stored in the smart card, and generates a verification signal when the computer identification signal stored in the non-volatile memory matches the user identification signal stored in the smart card. The power control circuit generates a start signal in response to the verification signal so as to start the computer system.
