笔记本电脑的小体积带来的散热问题是一直困扰着笔记本性能提升的障碍。毫无疑问,最好的解决办法就是节能。在世纪之交,处理器的节能技术SpeedStep取得了相当进展,同时在东芝等笔记本厂商相关技术突破的推波助澜下,能够更高效智能管理电源应用了SpeedStep的PⅢ联想东芝笔记本电脑终于问世。目前笔记本电脑可行的节能的相关技术主要有以下三点,首先,是CPU自身的能源管理。作为计算机心脏的中央处理器,一向以恒定频率工作,仿佛天经地义。而从效率角度讲这样做并不经济。采用了英特尔SpeedStep技术移动奔腾Ⅲ处理器的东芝新品笔记本电脑使这一切成为历史。新的处理器提供了两种不同的工作模式:接电状态时的最大性 The cooling problem caused by the small size of a laptop is a hurdle that has plagued laptop performance. There is no doubt that the best solution is energy saving. At the turn of the century, SpeedStep, a processor energy-saving technology, has made considerable progress. At the same time, PIII Lenovo’s Toshiba laptop, which uses SpeedStep to make power management more intelligently and intelligently under the help of notebook manufacturers such as Toshiba, has finally come out. Currently available laptop energy-saving technologies related to the following three points, first of all, is the CPU’s own energy management. As the computer heart of the central processor, has always been to work at a constant frequency, as if justly. This is not economical from the efficiency point of view. Toshiba’s new laptop, powered by Intel SpeedStep technology and a mobile Pentium III processor, makes that all history. The new processor provides two different modes of operation: the maximum power state
