Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to real-time computer thermal management and power conservation, and more particularly to an apparatus and method for decreasing and increasing central processing unit (CPU) clock time based on temperature and real-time activity levels within the CPU of a portable computer.

[0003] 2. Description of the Related Art

[0004] During the development stages of personal computers, the transportable or portable computer has become very popular. Such portable computer uses a large power supply and really represents a small desktop personal computer. Portable computers are smaller and lighter than a desktop personal computer and allow a user to employ the same software that can be used on a desktop computer.

[0005] The first generation “portable” computers only operated from an A / C wall power. As personal computer development continued, battery-powered computers were designed. Furthermore, real portabili...
