我在 HP 625 笔记本电脑（AMD Turion P540 处理器，4 GB RAM）上运行 Ubuntu 16.04（64 位）。除了我认为系统对风扇速度管理不善，导致我的处理器容易发热之外，一切都运行顺利。如果我使用交流电源，一切似乎都运行正常，但如果我拔掉笔记本电脑的电源，风扇就会停止，只有当温度达到非常高的温度（70 摄氏度）时才会重新启动，然后旋转得很快。我的挂起功能也遇到了同样的问题，如果我唤醒，风扇又不转了。
有什么解决办法吗？我在 Windows 7 上没有遇到这些问题（我双启动我的系统）。事实上，使用 Windows 7 时我的系统总体运行温度低 10 度（我安装了 lm-sensors）。奇怪的是我的笔记本电脑最初配备的是 SLED 11，因此应该完全兼容 Linux。
感谢帮助！

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y
Module cpuid loaded successfully.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): y

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y
Probing for `National Semiconductor LM78' at 0x290... No

Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): y

答案1
您有两个温度传感器，温度分别为 53 摄氏度和 20.9 摄氏度，此外sensors-detect在 i2c 地址 0X28 处发现了一些东西，但无法确定它是什么。您的 BIOS 支持风扇控制吗？使用这个会是最简单的选择吗？
