我的笔记本电脑在使用 YouTube 时短时间后关机了好几次。我能感觉到底部有热量。在关机前,它会显示一个黑屏,上面有一些文字,持续约一秒钟。
我正在运行 Xubuntu 12.04。我尝试在 Adobe Flash 播放器和 HTML5 上运行它。它唯一的专有驱动程序是 WiFi 卡。笔记本电脑运行 Windows Vista 双启动。我对 Linux 不太了解,所以如果能提供简单的说明就更好了。
系统规格(以防它们可能有助于诊断):
- 戴尔 Inspiron 1525(2008-09 年)
- 英特尔赛扬 2.00 GHz
- 2GB 内存
- 32 位
- 110 GB 左右的硬盘
- 显卡是“移动式英特尔 965 高速芯片组系列”
我觉得我明白你在说什么了
grep -iE "(emergency|temperature)" /var/log/syslog
得到
Jun 20 01:19:24 ubuntu kernel: [ 3617.333801] Critical temperature reached (99 C), shutting down.
Jun 20 01:34:21 ubuntu kernel: [ 867.196196] Critical temperature reached (99 C), shutting down.
Jun 20 02:43:52 ubuntu kernel: [ 1708.282274] Critical temperature reached (99 C), shutting down.
这是它过热的三次——全部都是:

非常感谢你的帮助,清洁后的风扇现在运转正常,但无法弄清楚 amd 专有驱动程序
答案1
至于硬件部分:
我最近在相同型号(使用 Windows)上解决了相同的问题。您很幸运,在此型号中,清洁 CPU 冷却器非常容易。您只需打开 CPU/RAM 的小盖子,拧下冷却系统及其盖子,然后清洁散热片上的灰尘。不仅仅是风扇上的灰尘。想想这是您的笔记本电脑“呼吸”的唯一方式,它被灰尘制成的“毯子”堵住了!您也可以更换导热化合物。这两者结合起来肯定会让事情好得多。
类似这样的视频可能会对你有帮助。(你只需要前两分钟)
至于软件部分:
尝试使用 AMD 的 GPU 专有驱动程序。就我而言(其他型号),它大大降低了温度。不过,开源驱动程序的省电功能最近可能有所改变。
