我在 HP nc4400 笔记本电脑上运行 Debian 7。这是一台配备 Intel Centrino 芯片组的旧笔记本电脑。它运行良好，只是风扇打开 10 秒，然后关闭 20 秒，然后打开 10 秒，依此类推。
BIOS 没有提及任何有关 ACPI 或 APM 的信息。dmesg | grep -i "acpi"返回这个：

我运行lm_sensors并让它在我不太记得的配置文件中添加一行 - 但这没有帮助。
（编辑：它在 /etc/modules 中添加了“loop”和“coretemp”，并让我重新启动服务来实现它。）
当使用交流电源运行时，我可以从 BIOS 永久打开风扇，但我宁愿在必要时打开或关闭，而不是每 10-20 秒不断地打开和关闭。
