When a 1.4 GHz laptop is operating at 800 MHz, the MOST likely cause is that ______.

A.
processor throttling technology is being used

B.
the incorrect processor is installed

C.
the jumper settings are incorrect

D.
hyper threading technology is being used

Explanation:
CPU throttling or processor throttling refers to a series of methods for reducing power
consumption in computers by lowering the clock frequency. Other methods include reducing the
supply voltage and the capacitance. CPU throttling is mostly employed in mobile computing
settings, where reduced power consumption means more battery life and less heat output. Less
heat output, in turn, allows the system cooling fans to be throttled down or turned off, thus further
increasing power savings.
