风扇不适用于Acer Aspire 5315
我最近在我的旧笔记本电脑上安装了lubuntu 11.10（acer aspire 5315 celeron）并观察到风扇在lubuntu方面工作不正常。我觉得奇怪的是它在windows vista下工作正常。
我怎么能解决这个问题？
许多Acer笔记本电脑需要acerhdf才能正确控制风扇速度。 如果没有acerhdf，Acer 1810TZ会产生很多噪音（运行Ubuntu并连接到电源）。 不幸的是，您的笔记本电脑似乎没有得到官方支持（您的模型未在源代码部分中列出，请参阅下面的代码块）。 您仍然可以强行运行它，但如果您不知道这是否会损坏您的硬件，这不是一个好主意。 运行dmesg|grep acer来检查是否有来自acerhdf的消息（它应该包含在更新的内核中）。

通过更新BIOS解决了这个问题
