Abstract: A voltage regulator may switch in an extra load when the voltage regulator changes from a higher to a lower output level in response to a processor change of state in a processor-based system. The additional load at the lower voltage level in the processor-based system may decrease the latency in the voltage level transistor, improving processor performance.

Abstract: A system includes a component, a detector adapted to detect generation of a power management event, and a controller adapted to transition the component from a first performance mode to a lower activity state in response to the power management event. The controller is adapted to change a setting of the component to a second, different performance mode while the component is in the lower activity state. The power management event may be generated in response to a change in the system's power source, an over-temperature condition, or a user command.

Abstract: A system and method for upgrading a computer is disclosed. Certain essential chips present in the original computer system are functionally, but not necessarily physically, removed from the computer system. Functions which would otherwise be performed by the original chips are instead performed by higher-performance chips on a plug-in module which is plugged into the computer system. The functional removal of the certain chips from the original computer system is achieved through simple insertion of the plug-in module. No replacement or substitution of original chips or boards is necessary. Furthermore, upgraded computer systems may be further upgraded by replacement of a first plug-in module with a second plug-in module with different performance characteristics.
