Patent number: 6282662Abstract: Method and apparatus for selectively overriding a prepackaged power management driver of a portable personal computer so that data transmitted to the CPIU of the computer by a device, such as a “real time” serial communicators device connected thereto, is not lost during the CPUs latency “wake up” period following a CPU power-down operation. An override system stored in memory comprises an override flag which may be set or cleared by a user or the computer. If the override flag is set, then the power management system is prevented from reducing power to the CPU so that the occurrence of a CPU latency period and thus potential for loss of data is avoided.Type: GrantFiled: August 4, 1995Date of Patent: August 28, 2001Assignee: Dell USA, L.P.Inventors: Charles Zeller, James L.

Patent number: 6272618Abstract: A system and method for handling system management interrupts in a multi-processor computer is disclosed. When the computer enters system management mode, the method uses the registers of each processor to get currently executing opcode to determine what each processor was doing before the interrupt. The method may have to first translate address information to locate the actual physical location of the currently executing opcode. The registers are stored in memory and the contents of the registers can be used to determine if the current processor caused the system management interrupt. If so, then the method now knows which processor caused the interrupt and can handle the interrupt accordingly. If, however, the processor was not the one that caused the interrupt, or if another processor also caused an interrupt, the method then repeats the above steps for the next processor of the multiprocessor system.Type: GrantFiled: March 25, 1999Date of Patent: August 7, 2001Assignee: Dell USA, L.P.Inventors: Benjamen G. Tyner, Mark Larson

Patent number: 6268806Abstract: A multimedia computer keyboard is provided having one or more high fidelity, diaphragm-type speakers mounted within the keyboard. Mono or stereophonic wiring to each speaker is achieved using existing keyboard cable extending from the keyboard to a keyboard connector arranged upon a host computer. A terminal at the end of the keyboard cable can plug directly into the keyboard connector, such that the terminal can receive an audio output signal generated from a sound card placed within the computer. Accordingly, audio output can be sent to the computer keyboard as an integrated system in order to achieve multimedia function.Type: GrantFiled: January 19, 1996Date of Patent: July 31, 2001Assignee: Dell USA, L.P.Inventors: David L.
