Linux CPU Speed

Tnego un equipo tope de gama, máxima velocidad, disco SSD grande, una gran resolución, display con mucho brillo, mucha RAM y todo maravilloso.....
Excepto, que cuando estoy trabajando con la batería, solo dura unas 3 hs. a veces menos...

Me puse a investigar y pude configurarlo correctamente con dos scripts, uno de MAX CPU y otro de SLOW CPU.

La idea es usar varios paquetes de gestión de CPU, cpufrequtils y especificarle que quiero.
En mi portátil estos valores funcionan correctamente, pero en otros dependiendo del Micro puede que las velocidades MIN y MAX deban ser otras.

MAX POWER
