My experience with Lenovo Laptops (I've got a 3000 N200) is that the fan control is performed by the BIOS. Typically there are periodic System Management Mode interrupts into the BIOS and the fan is controlled by this. So, the issue may be that there is a sensor fault, or the BIOS is not doing the right thing.
My Lenovo was playing up after nearly 3 years of use and cleaning the dust out of the fan grill outlet solved my sporadic fan overheating issues. http://smackerelofopinion.blogspot.com/2010/09/hot-laptop.html Secondly, I checked the Lenovo website and it appears there are some newer BIOS images available, so maybe these contain updates that *may* be relevant. -- Fan malfunction on Lenovo 3000 N100. https://bugs.launchpad.net/bugs/668413 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
