200411352

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.
