A power supply apparatus of a computer system and a method for controlling a power sequence thereof are provided. The power supply apparatus includes a power sequence module, a voltage supply unit, and a state recording module. The power sequence module provides voltage enable signals in turn according to first power-good signals. The voltage supply unit provides power voltages in turn according to the voltage enable signals and returns second power-good signals. Components in the computer system also provide third power-good signals when the components receive the power voltages. When one of the third power-good signals is converted from enabled to disabled, the state recording module delays a tolerance period according to the component corresponding to the third power-good signal, and converts the first power-good signal corresponding to the third power-good signal from enabled to disabled after the tolerance period is delayed.

A power redundant system is provided. The power redundant system includes N first voltage generators, M second voltage generators, a switch unit and a control unit. A voltage of the i-th first voltage generator and a voltage of the j-th second voltage generator are equal. When a power good signal is enabled, the control unit enables a power control signal to control the switch unit so that an output of the switch unit is connected to an output of the j-th second voltage generator. When a power supply signal is enabled and the power good signal is disabled, the control unit disables the power control signal to control the switch unit so that the output of the switch unit is connected to an output of the i-th first voltage generator. Therefore, the first voltage generator and the second voltage generator of the system can backup each other.

A pivot device has a pivot axle fastened on a cover of a lap top computer, a seat fastened on a chassis of the computer, and a first ring and a second ring respectively mounted around the pivot axle. The second ring and an elastic device are respectively mounted on the seat, and the second ring has two cutouts. Two lugs are respectively defined on the first ring and correspond to the cutouts. A nub is formed on an outer circumference of the first ring so that the nub presses against the elastic device. Hence, the cutouts are mated with the lugs by pushing so that the cover can be raised or lowered to the chassis and can be controlled to prevent colliding with the chassis.

A system error analysis device which includes a top unit and a storage unit coupled to the top module is mentioned. The storage unit is configured to store each of the input data, each of the output data and each of the bus data transmitted by the top unit. When receiving an interrupting signal, the system error analysis device outputs the input data, the output data and the bus data stored as soon as the interrupting signal is received and the input data, the output data and the bus data stored before the receiving of the interrupting signal. Accordingly, by comparing and analyzing the data output by system error analysis device, the system employing the system error analysis device is able to obtain the reason of the generation of the interrupting signal.
