Ubuntu 20.04 - 过热后关机

  • 772

我用的是Thinkpad L13。现在，我遇到了热问题，尤其是在满载情况下。当我运行使用所有内核的 Python 程序时，我的笔记本电脑很快就会关闭。

到目前为止我尝试了什么？我在我的机器上安装了 TLP 和 thermod。此外，我将 BIOS 中的 Intel 设置更改为“Balanced”。

最近发生了两件事：

  1. 我已经安装了 Ubuntu 20.04。

  2. 由于我的 ThinkPad 的图形问题，他们最近更换了我的主板。也许这是一个硬件问题，比如冷却器不合适？

在此之前，没有出现任何问题。

该命令grep -i -e temp -e therm /var/log/syslog*在这种情况下会产生以下输出：

编辑（2020 年 5 月 1 日）：

今天，我开了一个 Zoom 会议，笔记本电脑变热了，以至于在会议期间它关闭了。这不是应该发生的，对吧？这里发生了什么？我没有在这里进行复杂的计算。可能和我装上电源有关系吧？

编辑（2020 年 5 月 9 日）：

我将性能设置设置为最高水平，并考虑了与我的笔记本电脑的各种温度评估相同的压力测试。在 Windows 上，我得到的值与它们相似。因此，我认为，这一定是新的 Ubuntu 20.04 的问题。不知何故，Ubuntu不会限制频率以使温度下降。

编辑（2020 年 7 月 19 日）：

我联系了联想支持，他们修理了我的笔记本（不管他们做了什么）。几个星期以来，它运行良好。现在，我又遇到了同样的问题。

我已经更新了我的 BIOS 版本，这会有所帮助，但会带来另一个问题：一旦温度接近过热，cpu 就会降低到 400Mhz。结果，我的笔记本几乎不能用于要求苛刻的任务。

作为一种可能的解决方案，我停用了英特尔的涡轮增压。温度现在在可以忍受的范围内，一切都足够顺利。这是我愿意接受的妥协。

3 个回答

  1. 在您的情况下，很难通过 askubuntu 对硬件+软件系统进行全面诊断。硬件问题尤其困难。

    可以通过在您的 Ubuntu 20.04 中并排安装另一个操作系统并执行密集测试来提供诊断第一步的替代方法。

    您可以运行相同的 Python 程序（如果您可以将其配置为使用所有内核）。即便如此，它可能不会在与您看到的关机完全相同的条件下运行。那里有很多用于测试性能的应用程序，它们应该足够好（甚至比您的程序更严格）。而且它不会受到您可能的 Ubuntu 20.04 配置的任何“污染”。

    稍后，当完整诊断完成后，您可以摆脱此操作系统并为您的 Ubuntu 回收空间。

  2. 尝试这个：

    mkdir ~/helper

curl https://raw.githubusercontent.com/Sepero/temp-throttle/stable/temp_throttle.sh -o ~/helper/temp_throttle.sh
chmod +x ~/helper/temp_throttle.sh

cat <<EOF > ~/helper/temp_down.sh 
#!/bin/bash
/usr/bin/sudo -H -S <<< "yourpassword" -p GNOME_SUDO_PASS -u root bash -c '~/helper/temp_throttle.sh 65'
EOF

chmod +x ~/helper/temp_down.sh

    测试它：

      sh ~/helper/temp_down.sh

    这只是为了测试它是否有效，我不建议将您的密码插入到容易获得的文本文件中。

    您可以将其添加到启动应用程序中。
