Lenovo L512 (2597AB2) ubuntu 12.10
I've purchased LENOVO ThinkPad L512 (2597AB2) laptop, and experiencing some problems with it in Linux. Particularly, after some time (it may be 10 minutes, or may be day) buttons Fn + F1, Fn + F2, ..., Fn + F12, Insert, Delete, Home, Volume+, Volume-, Volume Mute and POWER are no longer works. In addition, the CPU fan is behaving strangely does not respond to the temperature increase. And it does so until one completely cuts laptop from the power (no AC, no battery), reboot or on/off cycle are unhelpful.
yet the topic was discussed here https://bugzilla.kernel.org/show_bug.cgi?id=27792

Most probably the effects that you get are a byproduct of bad power management, due to the BIOS.
Do a
ubuntu-bug udev
and follow the instructions.
The result would be a bug report with technical information from your computer.
