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. The event controller sends an interrupt to the system controller to cause the CPU to execute the first power management routine, causes the clock generator to change the host clock signal to a new frequency while the system controller is in the idle state, activates the system controller after the host clock signal has changed to the new frequency, and causes the CPU to execute the second power management routine. By changing the host clock signal to the new frequency when the system controller is in the idle state, the event controller prevents the system controller from crashing. By changing the frequency of the host clock signal, the operating frequency of the bus is changed, and by changing the operating frequency of the bus the total power consumption of the computer system is changed.

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.

A volume control knob for use with a laptop computer uses the engagement between the springs and the connecting plates to generate different messages. The messages will then be transmitted to the chip received in the secondary control device. With the messages received by the chip, the volume of the laptop computer is controlled.

An apparatus for connecting a peripheral device to a computer is disclosed. The apparatus comprises a detection means on each peripheral input/output port for detecting a peripheral device. The detection means generates a system interrupt to the computer. The computer executes an interrupt service routine of the basic input/output system. The interrupt service routine determines the peripheral device that is newly connected and sets related flags and data for the computer operating system and basic input/output system. The optimal parameters for integrating the peripheral device to the computer is set and the peripheral device is ready for use.
