很多设备不能识别 风扇不停转。

[IfI]

我是本本，在xp下风扇很正常，高cpu占用率的时候才转，现在是不停的最高速度转，有些心疼。

见附件图，图标为白色方块的都是不能识别的设备。

难道要装主板驱动？

一般来说Unknown只要不影响使用就没关系的

[zhuqin_83]

正常，我这里也是一样的。7.04倒能认出来绝大部分。
风扇的问题应该和acpi电源管理有关。

我查了一下，坛子上有兄弟用一个叫cpufreq-info的工具，他们是可以看到cpu的状态的，见这个贴子

viewtopic.php?t=31050

而我只能看到这个
执行 cpufreq-info
结果：

代码： 全选

cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
 no or unknown cpufreq driver is active on this CPU

现在风扇不停转我估计和不能识别cpu有关吧。

麻烦帮忙看看你的机器上，用这个工具是什么效果，行不？

我要改动一下其中几项可疑部分。唉，东芝索尼ibm甚至华硕都有直接支持阿……我是可恶的lenovo。

[zhuqin_83]

不是不能识别吧？
你是什么cpu？
那个帖子是我写的。
所以，效果就是帖子里面所写的一样。

[IfI]

我的是dothan 1.73

把CONFIG_ACPI_FAN=m 改为y了，还是那样，郁闷。

继续改。

[zhuqin_83]

你的跟我一样啊，为什么不行？
论坛里面有个帖子叫 电源管理的，你搜一下。是精华贴。

是这个吧，我看了，里边也一样用到了 cpufreq-info ，问题是我根本就没有信息阿，你的cpu和我一样，你有具体信息吗？

[IfI]

我装了个x86info

研究过过程中的两间趣事：

1,发现一个和我情况几乎一样的贴子，解决办法把我寒死了

2执行powernowd忘了加sudo

PowerNowd encountered and error and could not start.
Please make sure that:
- You are running a v2.6.7 kernel or later
- That you have sysfs mounted /sys
- That you have the core cpufreq and cpufreq-userspace
modules loaded into your kernel
- That you have the cpufreq driver for your cpu loaded,
(for example: powernow-k7), and that it works. Check
'dmesg' for errors.
If all of the above are true, and you still have problems,
please email the author: clemej@alum.rpi.edu

我根据

这个文章操作，报错如下：

sudo sensors
Can't access procfs/sysfs file

For 2.6 kernels, make sure you have mounted sysfs and libsensors

For older kernels, make sure you have done 'modprobe i2c-proc'!

sysfs怎么搞？

[zhuqin_83]

我怀疑你是不是把acpi或apmd和其他一些服务给关掉了？
sudo apt-get install sysv-rc-conf
sudo sysv-rc-conf看看。
