probleme cu un procesor

Pai ii scade frecventa cand nu are ce lucra procesorul pt. a mai salva din baterie.

SpeedStep™ is a series of technologies (including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel processors. SpeedStep allows the clock speed of a processor to be dynamically changed by software. Running the processor at higher clock speeds allows for better performance. However, when the processor is run at a lower speed, its core voltage can be reduced; both of these changes allow for reduced power consumption and heat dissipation. This can conserve battery power in notebooks, extend processor life, and reduce noise from cooling apparatus. By using SpeedStep, users can select the balance of power conservation and performance that best suits them, or even change the clock speed dynamically as processor burden changes.

For example, a Pentium M processor marketed at 1.5 GHz can run at any speed between 600 MHz and 1.5 GHz, at 200 MHz increments, using SpeedStep III.

However, older processors have fewer increments, such as the Pentium 4-M. For example, a 1.7 GHz Pentium 4M can run at 1.6 GHz, at 1.2 GHz, and at 786 MHz.

SpeedStep technology is partly responsible for the reduced power consumption of Intel’s Pentium M processor, part of the Centrino brand.
