Abstract: A computer system has a central processing unit (CPU), a memory, a first power management routine, a second power management routine, a clock generator, an event controller, and a system controller for implementing a bus. The system controller uses a host clock signal that determines the operating frequency of the bus. The clock generator generates the host clock signal. The first power management routine has computer code that saves state information of the computer system in the memory and that places the system controller into an idle state. The second power management routine restores the computer system using the state information stored in the memory.

Abstract: An elastic sheet structure for the contact of a battery set used in a portable computer is provided. It comprises a positive-end elastic sheet and a negative-end elastic sheet having a central hole thereon. The size of the positive-end elastic sheet is smaller than that of the central hole of the negative-end elastic sheet. This invention may assemble several electric cells into a complete battery set for a portable computer. The special design avoids damaging the portable computer due to the misplacement of the positive end and the negative end of the electric cells of the battery set. It also provides a simple and convenient way to assemble the battery set.

Abstract: A portable computer having identification marks. The identification marks are beside screw holes in which screws are to-be-screwed. The identification marks show the appearance of the screw, the cross-section patterns or the 3-dimentional patterns of the screws.

Abstract: A friction hinge for a notebook computer having a base and a liquid crystal display (LCD) is provided. The hinge comprises a pair of sleeves each having one end mounted to the base of the notebook computer and the other end pivotal relative to the sleeve, and a bracket member mounted to the LCD, each end of the bracket member fixed to the other end of each sleeve. This can greatly enhance the structural strength for preventing the LCD from deforming or damaging after long time of holding the notebook computer.
