[讨论] IBM T60 在 Ubuntu 下 CPU 的高烧

[markli]

本本装 Ubuntu 一年有余了，今天来测试了一下温度，

缘由：显示屏下方有两个金属柱，偶然发现左侧那个极为烫手，突然有兴趣测测CPU的温度，以下是列表信息，貌视有些不太正常。。。。

湿度：
mark@tiger:~$ acpi -t
Battery 1: charged, 100%
Thermal 1: ok, 79.0 degrees C
Thermal 2: ok, 78.0 degrees C

工作频率：
mark@tiger:~$ cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 1000 MHz - 2.00 GHz
available frequency steps: 2.00 GHz, 1.67 GHz, 1.33 GHz, 1000 MHz
available cpufreq governors: powersave, userspace, ondemand, conservative, performance
current policy: frequency should be within 1000 MHz and 2.00 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 1000 MHz.

主要的应用：
virtualbox windows xp 只是开着挂了2个QQ，没有消息
smplayer 看了一部电影

有点吓人，哥们儿们的电脑咋样？测过没?

这两天比较注意机器的健康状况，今日有两次死机事件，重启后测CPU的温度在七十多度，随之将工作频率锁定在 1Ghz (Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz )
CPU 的可调范围为：
available frequency steps: 2.00 GHz, 1.67 GHz, 1.33 GHz, 1000 MHz
即，1G 是最低的，使用（ 仅仅用 firefox2 看新闻 ）半小时以后再测温度，结果如下：

Battery 1: charged, 97%
Thermal 1: ok, 58.0 degrees C
Thermal 2: ok, 57.0 degrees C

是不是散热装置有问题了？这个温度不正常啊

[hcym]

不太懂散热装置

我那本倒是拔凉拔凉的

我的：~$ acpi -t

Thermal 1: ok, 54.0 degrees C
神舟本，散热肯定没你的好，但是U主频低，应该差不多。

继续高烧，创新高了：
root@tiger:ibm# acpi -t
Battery 1: charged, 97%
Thermal 1: ok, 84.0 degrees C
Thermal 2: ok, 85.0 degrees C

[carbont]

玩模拟器和在线看视频，烧CPU的事情会让本本相当热。

我常常还是同时干这两件事情……
都不去理会了，电脑烧坏了再买了－－没有工作的学生同志还是小心一点儿的好。

[markli]

最新情况：
Battery 1: charged, 97%
Thermal 1: ok, 94.0 degrees C
Thermal 2: ok, 93.0 degrees C


奇怪的是还没死机，莫非，死机不是高温的原因？

[markli]

风扇转速已达到 4355 了：
mark@tiger:ibm$ cat fan
status: enabled
speed: 4355
level: auto

[hcym]

我都是限频在800M用

一切正常

[vvhh2002]

T60P 和你状况相同

[markli]

我装 7.10 也有两次死机，同一天下午，看一部电影的时候，也就是2个小时之内死了两次机，以后就再也没有了，我特意将U的温度提高，想把死机的情况重现，但到了94度都不死，我也就不敢再试了，昨天晚上升级到了 8.04，还没有开始用

[rocky22]

装一下powertop试试看。

[rocky22]

代码： 全选

sudo apt-get install powertop
sudo powertop 

[gaby]

firefox就是CPU占用率太高。还说是省资源，也不知道升到3.0到底改进了什么。

[jiabinsun]

X60 和你情况差不多

没跑个啥70多度

风扇狂转。没有散热底座直接90多度。。。

有装powersaved

powertop

kpowersave

等
