我有一台 HP pavilion dv7，我使用的是 ubuntu 12.04，所以 sandybridge cpu 的過熱問題好多了。然而，我的筆記型電腦仍然太熱，無法放在腿上。問題是風扇在啟動前等待時間太長，因此介質溫度太高。當我使用 Windows 7 時，筆記型電腦在室溫下很冷，我絕對沒有問題。在窗戶上風扇總是以非常低且非常安靜的速度旋轉，因此熱量會不斷被帶走，而不會達到不舒服的溫度。如何強制電腦在 ubuntu 上也這樣做？
PS BIOS不能讓我控制這種事情，這是我的經驗流明感測器和風扇控制

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
AMD K8 thermal sensors... No

Intel digital thermal sensor... Success!
(driver `coretemp')
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No

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
我的情況是不是太絕望了？
答案1
你應該考慮安裝 jupiter
您可以用它選擇電源模式，它非常容易控制，我只是將其設置為開機命令，您不會注意到您的筆記型電腦已打開，直到您開始使用重型應用程式
打開終端並執行此操作。
新增儲存庫
sudo add-apt-repository ppa:webupd8team/jupiter
更新
sudo apt-get update
安裝木星
sudo apt-get install jupiter
對於閱讀本文並使用華碩 EEPC 上網本的其他人，請安裝此內容
sudo apt-get install jupiter-support-eee
祝你今天過得愉快 ：）
答案2
我看到 Mysterio 和 TheX 已嘗試提供協助，但尚未發布任何答案。我只是建議您嘗試用壓縮空氣吹掉系統中的一些灰塵。在我的計算機上執行此操作後，風扇似乎運行得更好（無論如何聲音更大）並且系統運行得更涼爽。
我認識到這並不能解釋 Ubuntu 和 Windows 之間的差異。
還有一些 acpi 核心設定可能值得嘗試。看：
您可以嘗試從 Ubuntu CD 啟動。 （例如，acpi=off）。看：
答案3
如果您有一台使用了兩年以上的任何類型的筆記型電腦，那麼值得取出風扇並清潔散熱器格柵上的絨毛和灰塵。你通常會在那裡發現一塊巨大的地毯！我使用的筆記型電腦目前運行很熱，因此我用舊筆記型電腦電池支撐它的正面。這會將底座抬離桌子並實現更好的空氣流通。最後，如果您有技術感並且可以冒險，請觀看一些 YouTube 視頻，獲取一些導熱膏，清潔並重新塗抹處理器和 GPU 上的散熱器。這確實帶來了不同。
答案4
我有一台 pavilion DV7 6000 系列。 Intel Quad 晶片，win 7，大約 2 年了。起初它運作得非常涼爽和安靜。加班時聲音越來越大，越來越熱。然後我在啟動時開始收到風扇無法正常工作的警告。但它仍然在工作，聲音很大。
最後我把機器拆了。惠普有一個很棒的線上維修手冊可以下載。它提供了詳細的拆卸和維修說明。您需要的唯一工具是一個小十字頭和一根牙籤。裡面的一切都佈滿灰塵，尤其是風扇區域。我用壓縮空氣將其全部清理乾淨，壓力為 40 psi。它工作起來就像新的一樣。他們的警告不再出現。
最後，我不得不說惠普打造了一台漂亮的機器。只需很少的工具和專業知識即可存取所有部件。他們提供完整的說明和精美的圖片。這是我過去 15 年來發現的最好的商品之一。
