\"CPUSpeed dynamically controls CPUFreq, slowing down the CPU to conservepower and reduce heat when the system is idle, on battery power oroverheating, and speeding up the CPU when the system is busy and moreprocessing power is needed. Using CPUSpeed can significantly increase alaptop computer's battery life and significantly reduce the heat itgenerates while still allowing your system to perform at top speed whenyou need it.\"
