Ubuntu 16.04 LTS：风扇在HP Envy 6-1154er上以最大速度运行
我尝试了很多不同的东西。 我花了几天时间用谷歌搜索并尝试不同的步骤来解决这个问题。 但没有成功。
我已经在这个问题上询问了这个问题： 粉丝exception行为：坚持并坚持最大速度（HP Envy 6-1154er和Ubuntu 14.04） 。 它列举了我尝试过的几个步骤。
我试过安装TLP。 现在我安装了LMT（笔记本电脑模式工具）： 16.04升级后笔记本电脑无法控制风扇速度 。 我安装了Ubuntu 16.04升级版。 我以前有14.04（问题是因为它安装后存在）。 我安装了4.6内核。 所以，由于我有新的操作系统，我决定再次询问，因为我的上一个主题似乎无法回答。
可能的解决方案：我注意到当风扇工作在最大速度并且温度在59-69C范围内时（CPU是“冷”）如果我从笔记本电脑上拔下交流电源，风扇的速度会在一对夫妇之后变低几秒或有时几十秒。
所以，我想如果我能够以某种方式告诉LMT或操作系统，笔记本电脑一直在电池上，不管它与电源的实际连接如何，我可能会得到我想要的东西：轻轻地工作风扇。 这是我唯一无法击败的事情。 我不想让窗户回来。
q@4xybook:~$ sudo laptop_mode status 插入交流电源时给出此信息。

这个如果它被拔掉了
q@4xybook:~$ sudo laptop_mode status ... /sys/class/power_supply/ACAD/online: 0 Laptop mode enabled, active [unchanged]
有任何想法吗？

一个善良的灵魂能告诉我：是否有可能让笔记本电脑始终以电池模式工作而不管其实际状态如何？
在我做了@Ingo建议的事情之后，事情变得很好。 我删除了intel_powerclamp 。 通往地狱的道路完全取决于善意……
sudo rmmod intel_powerclamp
要永久禁用它并完全禁止加载它，另外：
cd /etc/modprobe.d sudo su echo install intel_powerclamp /bin/true >intel_powerclamp.conf
intel_powerclamp：启动/停止强制空闲注入
