以Intel的資料表示’操作頻率降低2()%,再配 電壓的降低’理論上耗電量可以降低到原先操作模式^ 到六成之間;以600MHz的筆記型電腦為例,使用者外出 用筆記型電腦時,通常無法使用交流電源(Ac p〇wer) 此時’筆記型電腦只能吃電池的電源,此時,⑽會“ 切到1.35V/500MHZ之低壓/低速模式,耗電量大幅降低。 而電池的供應時間也得以延長,又當筆記型電腦移到可 接AC Power的地方時,系統便自動切回16¥/6〇〇〇2之罩 Μ /高速模式。According to Intel's data, 'the operating frequency is reduced by 2 ()%, and then the voltage is reduced.' In theory, the power consumption can be reduced to the original operating mode ^ to 60%; taking a 600MHz notebook computer as an example, users go out When using a notebook computer, AC power (Ac power) is usually not available. At this time, the notebook computer can only use battery power. At this time, it will "switch to the low voltage / low speed mode of 1.35V / 500MHZ and consume power. The battery supply time has also been extended, and when the notebook computer is moved to a place where AC Power can be connected, the system automatically switches back to the 16M / 6M2 high-speed mode.
