Title:
  [Lenovo ThinkPad L512 2597] Fan speed freezes, and hotkeys stop
  working

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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
