"Nearly seven years ago at the Intel Developer Forum in Palm Springs California, Intel had first demonstrated Geyserville Technology. This dual-speed technology, when paired with a 0.18-micron mobile Pentium processor, had offered a distinct advantage as it was able to run in two processing modes -- maximum performance and battery optimized. Geyserville Technology allowed the processor to run slower and decrease the voltage when the mobile solution was running off of a battery (in order to reduce power consumption and allow robust performance without sacrificing battery life), but when the laptop was then plugged into an AC outlet, the frequency would return to normal."
