An apparatus and method for cooling heat generating components within a compartment are disclosed. A cooling assembly isolates heat produced by a processor in a personal computer (“PC”) system and exhausts it from the PC prior to adversely affecting other components within the PC. A fan causes air to blow across the processor having an attached heat sink disposed within the cooling assembly, and the air exits the cooling assembly without adversely affecting the other components surrounding the processor. In one example, an alternative passage is provided for the air.

A modular floppy disk drive is designed to stand alone as an external drive or to be combined with a carrier to fit into a computer peripheral option bay configured for removable CD ROM drives. When used as an external floppy disk drive, the modular unit is connected to the personal computer through a connector and cable assembly. The carrier adapts the modular drive to the size and mechanical requirements of the peripheral option bay so that the modular unit can be inserted into the computer and used as an internal floppy disk drive.

A display apparatus is provided having a back light generated by waste heat of a system. A thermally illuminated strip is disposed on a surface of the display apparatus. The system has heat generating components, such as a CPU, which produce excess waste heat. A heat pipe conveys the heat from the heat generating components to the thermally illuminated strip. Once the heat generating component warms up, the thermally illuminated strip is illuminated by the conveyed heat and provides back lighting for the display apparatus. Although several other applications are appropriate, one particular application for the display apparatus is for a status LCD within a computer.

The performance of a computer system which use reduction of clock speed to conserve power is enhanced by dynamically adjusting the minimum number of clock cycles required for memory access ("wait states"). When the computer system decreases its clock speed, the minimum number of wait states is decreased to account for the longer cycle time. Likewise, when the computer system increases its clock speed, this invention determines whether any increase in the minimum number of wait states is required, and if so, implements such an increase.

The capability of a peripheral bus to provide an alternative low power source is combined with existing power management software that controls a computer's main power supply unit to provide stand-by power to logic in the computer that remains active to monitor the system environment for predetermined wake-up events. A self-powered Universal Serial Bus device supplies the minimal power needed by the active logic without the inefficiencies of a dual-stage power supply unit or the expense of incorporating both low-power and a full-power units.

A computer having an emergency protection program is disclosed. The emergency protection program turns off the computer in response to receiving a notification of an impending potential local emergency. In one embodiment, the program receives the notification from an external network site over an external network connection. In one embodiment, the program waits a predetermined amount of time prior to shutting down the computer, and also is responsive to an abort-shut down input to not shut down the computer, or an immediate-shut down input to immediately shut down the computer.

A pointing device for a computer, having switching mechanisms with perceptively differing actuation forces, is disclosed. In one embodiment, the pointing device comprises a housing, a sensor, a first switching mechanism and a second switching mechanism. The sensor is disposed within the housing and translates movement into an electrical signal. The first switching mechanism is also disposed within the housing and has a first predetermined actuation force. The second switching mechanism is also disposed within the housing and has a second predetermined actuation force. The second predetermined actuation force is perceptively different than the first predetermined actuation force.
