前言
我的是deepin系统，因为新买了magicbook pro笔记本（i5版)，在windows下续航能够有10小时，但是在linux下耗电迅速只能三四小时，所以我对系统进行了省电优化，能够日常使用可以续航7小时以上。
步骤一
安装tlp
sudo apt-get install tlp tlp-rdw
systemctl enable tlp
systemctl enable tlp-sleep步骤二
安装powertop
sudo apt-get install powertop
vim /etc/systemd/system/powertop.service写一个powertop的服务
其实就是写powertop --auto-tune自动优化
[Unit]
Description=PowerTOP auto tune
[Service]
Type=idle
Environment="TERM=dumb"
ExecStart=/usr/sbin/powertop --auto-tune
[Install]
WantedBy=multi-user.target同样也是enable该服务
systemctl enable powertop
步骤三
powersave写入cpu管理
vim /etc/rc.local好像默认是balance的，我设置省电模式，但是我没做cpu降频了，因为本身就是轻薄本我还得跑跑代码，降频怕带不动了。
#!/bin/bash
# save power
echo 'powersave' > /syshttps://img.qb5200.com/download-x/devices/system/cpu/cpu0/cpufreq/scaling_governor

echo 'powersave' > /syshttps://img.qb5200.com/download-x/devices/system/cpu/cpu7/cpufreq/scaling_governor
# powertop --auto-tune
exit 0
