我最近买了一台搭载 Skylake i7-6700hq 处理器的笔记本电脑，并且我设法安装了 Ubuntu 16.04，但是，我注意到笔记本电脑过热，导致使用 Ubuntu 时电池寿命非常短（1.5 小时，而使用 Windows 时可持续 6 小时）。
于是我运行了powertop，我注意到我的处理器从未低于 PC2 状态，因此即使在空闲时也是如此。我也尝试运行powertop –auto-tune，即使略有改善，处理器也从未低于 PC3。
我也尝试升级内核，从 4.4 ubuntu 升级到 4.7，但没有效果。
坦白说，我对这个问题一无所知，所以我来找你。我还附上了powertop输出。
感谢您的帮助 ！

答案1
首先，将主板固件更新到最新版本，并保持最新。
其次，请安装 intel-microcode 包（并且您必须使用 3.20160714.1 或更高版本，因此从 Ubuntu YY 或 Debian 获取它）。
确保重启后具有微码 0x9d 或 0x9e（在 /proc/cpuinfo 或内核日志中）。
这会有所帮助（至少会消除一些潜在的崩溃行为），但并不能解决所有问题。PC3 的 NVMe 问题仍然存在，这需要 Linux 内核中尚未包含的代码，以及英特尔尚未告知任何人的一些信息。
答案2
由于您的笔记本电脑配备了 NVIDIA 显卡（可能是“Optimus”配置），它可能会与您的处理器和集成显卡共享一个散热器。
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 卡的风扇已激活。
