默认CPU有自动管理电压以及评率功能。但在极端需要的时候，通过减少CPU性能来换取降低功耗，可以通过：
Powersave 模式
命令行输入：
#! /bin/bash cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor for file in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do echo "powersave" > $file; done cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
CPU 关闭部分核心
命令行输入：
echo 0 > /sys/devices/system/cpu/cpu1/online echo 0 > /sys/devices/system/cpu/cpu2/online echo 0 > /sys/devices/system/cpu/cpu3/online
