我有一台 HP pavilion dv7，我使用的是 ubuntu 12.04，所以 sandybridge cpu 的过热问题好多了。但是我的笔记本电脑仍然太热，无法支撑。问题是风扇在启动前等待的时间太长，所以中等温度太高。当我使用 windows 7 时，笔记本电脑的温度与室温一样低，我完全没有问题。在 Windows 上风扇总是以非常低且非常安静的速度旋转，因此热量不断被消除，而不会达到令人不舒服的温度。我如何才能强制计算机在 ubuntu 上也这样运行？
PS：BIOS 无法让我控制这种事情，这是我的经验流明传感器和风扇控制

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y
Module cpuid loaded successfully.
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No

Intel digital thermal sensor... Success!
(driver `coretemp')

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): y

Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!
Do you want to add these lines automatically to /etc/modules? (yes/NO)y
Successful!
Monitoring programs won't work until the needed modules are
loaded. You may want to run 'service module-init-tools start'
to load them.
Unloading i2c-dev... OK
Unloading i2c-i801... OK
Unloading cpuid... OK
al@notebook:~$ sudo /etc/init.d/module-init-tools restart
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service module-init-tools restart
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop module-init-tools ; start module-init-tools. The restart(8) utility is
also available.
module-init-tools stop/waiting
al@notebook:~$ sudo service module-init-tools restart
stop: Unknown instance:
module-init-tools stop/waiting
al@notebook:~$ sudo service module-init-tools start

al@notebook:~$ sudo pwmconfig
# pwmconfig revision 5857 (2010-08-22)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
我的情况是不是太糟糕了？
答案1
你应该考虑安装 jupiter
你可以用它选择电源模式，它非常容易控制，我只是将它设置为开机命令，你不会注意到你的笔记本电脑已经打开，直到你开始使用繁重的应用程序
打开终端并执行此操作。
添加存储库
sudo add-apt-repository ppa:webupd8team/jupiter
更新
sudo apt-get update
安装木星
sudo apt-get install jupiter
对于正在阅读本文并使用华硕 EEPC 上网本的其他用户，也请安装此软件
sudo apt-get install jupiter-support-eee
祝你今天过得愉快 ：）
答案2
我看到 Mysterio 和 TheX 尝试过提供帮助，但尚未发布任何答案。我建议你尝试用压缩空气吹掉系统中的一些灰尘。在我这样做之后，我的电脑风扇似乎运行得更好（无论如何声音更大），系统运行得更凉爽。
我认识到这并不能解释 Ubuntu 和 Windows 之间的区别。
还有一些 acpi 内核设置可能值得尝试。请参阅：
您可以尝试从 Ubuntu CD 启动。（例如，acpi=off）。请参阅：
答案3
如果您拥有一台使用超过两年的笔记本电脑，那么就值得将风扇取出并清洁散热器格栅上的绒毛和灰尘。您通常会发现里面有一块巨大的地毯！我现在使用的笔记本电脑运行起来很热，所以我用旧的笔记本电脑电池支撑它的前部。这样可以将底座抬离桌面，从而实现更好的空气流通。最后，如果您对技术有一定了解并且可以承担风险，请观看一些 YouTube 视频，获取一些导热膏并清洁并重新涂抹处理器和 GPU 上的散热器。这确实会产生很大的不同。
答案4
我有一台 pavillion DV7 6000 系列。英特尔四核芯片，win 7，大约 2 年前的机器。一开始它运行起来非常凉爽安静。但随着时间的推移，它变得越来越响，越来越热。然后我在启动时开始收到警告，说风扇工作不正常。但它仍然在工作，声音很大。
最后我拆开了机器。惠普有一个很棒的在线维修手册，可以下载。它提供了详细的拆卸和维修说明。你只需要一把小十字螺丝刀和一根牙签。里面所有东西都布满灰尘，尤其是风扇区域。我用 40 psi 的压缩空气将其全部清理干净。它像新的一样工作。警告不再出现。
最后，我不得不说 HP 制造了一台漂亮的机器。只需很少的工具和一点专业知识即可使用所有部件。他们提供完整的说明和精美的图片。这是我在过去 15 年里发现的最好的商品之一。
