摘要： A circuit (11) utilizing a serial advanced technology attachment (ATA) interface for transmitting connectivity signals from the serial ATA interface to a controller (10) in order for the controller to determine a status of connectivity of a hard drive disk (HDD) (21) to the serial ATA interface. The circuit includes an input end (A) connecting to a ground end of the serial ATA interface, and electronically connecting to a high voltage source; a positive-negative-positive (PNP) tripolar transistor (Q1), a first negative-positive-negative (NPN) tripolar transistor (Q2), a second NPN tripolar transistor (Q3), and an output end connecting a collector of the second NPN tripolar transistor with the controller for outputting voltage signals to the controller. The controller is a programmable microprocessor for determining whether or not the HDD is connected to the serial ATA interface, based on the voltage signals input to the controller.

摘要： An all-in-one computer includes a hard disk drive (HDD), a main body, a cover, and a fasten member. The main body defines a receiving space to receive the HDD, and a fasten hole. The receiving space is bounded by a number of walls. A first raised edge protrudes from the number of walls in the receiving space. The cover includes a board, a first hook, and a mounting piece defining a through hole. The board includes opposite first and second ends. The first hook extends from the first end. The mounting piece extends from the second end. When the cover is mounted to the main body, the first hook snappingly hooks an inner side of the first raised edge, the board is stopped by the first raised edge, and the fasten member can extend through the through hole and engage in the fasten hole.
