Question

我有戴尔 XPS L502X

我已经安装了金石 120 GB 的 SSD 之后我安装了 ubutu 16.04 并且我的电池在 100% 充电工作 1 小时 13 分钟时消耗非常快，而在窗口中它保持大约 4 小时

我该怎么办？？

Answer 1

1. 安装tlp（使用命令sudo apt-get install tlp），然后在笔记本电脑拔下后，在Tunables选项卡下，powertop最多参数应切换到“良好”（使用 r 刷新 powertop）。
2. 打开Software & Updates并在Additional Drivers选项卡上选择专有 gpu 驱动程序（如果可用）。intel-microcode如果它也可用，也可能是一个不错的选择。
