Ubuntu 16.04 Skylake过热
我最近买了一台登上skylake i7-6700hq处理器的笔记本电脑，我设法安装了Ubuntu 16.04，然而，我注意到笔记本电脑过热导致Ubuntu的电池续航时间非常短（1.5小时，而它持续6小时在Windows上）。
所以我运行了powertop ，我注意到我的处理器永远不会低于PC2状态，因此即使在空闲时也是如此。 我也试过运行powertop –auto-tune ，即使有轻微的改进，处理器也永远不会低于PC3。
我也试过升级内核，从4.4 ubuntu转到4.7，但它没有效果。
坦率地说，我对这个问题完全无能为力，这就是我要来找你的原因。 我也附加了powertop输出。
谢谢你的帮助 ！

首先，将主板固件更新到最新版本，并使其保持最新状态。
其次，请安装intel-microcode软件包（您必须使用版本3.20160714.1或更高版本，因此从Ubuntu YY或Debian获取）。
确保在重新启动后（在/ proc / cpuinfo或内核日志中）有微码0x9d或0x9e。
这将有助于一些人（它至少会让一些潜在的崩溃行为），但它不会解决所有问题。 PC3的NVMe问题仍然存在，这需要Linux内核尚未提供的代码，以及英特尔尚未告诉任何人的一些信息。
由于您的笔记本电脑配有NVIDIA显卡（可能采用“Optimus”配置），它可能与您的处理器和集成显卡共享散热片。
在这种情况下，安装Nvidia专有驱动程序可能会有所帮助：
-
sudo apt install nvidia-375
这有助于解决我的过热问题。 我想另一种方法是以某种方式使用nouveau驱动程序，或者确保nvidia卡的粉丝被激活。
