I always fixed it via updating to newer version of BIOS. This usually helps for 3 or 4 weeks. I don't know how to update BIOS by the same version. I tried this via bootable CD and I receive message something like "You have the newest version of BIOS. Update is not necessary. Exit". Same message showed up via Windows 7 BIOS update utility...I am pretty sure that update BIOS by the same version will help but i have no idea how to do this.
May i hope that Lenovo will deliver a permanent solution for this issue?
Thanks for your help.

hi everyone. i just had the same problem but i found a SOLUTION to fix it. i hope it's permament but i've been reading the problem returns. all you need to do is either upgrade to the latest bios if you dont have it, or, if thats not the case you need to downgrade the bios (you will find older versions on you laptop model support page) and then reinstall the latest one.
at the moment it seems the only solution for this problem is bios reflashing.
be careful when reflashing as things can go really bad if something crashes. have your computer plugged in at the time you are flashing and also just in case of a power surge have your battery charged.

I have 15'' model and the same problem exists in Ubuntu and in BIOS menu itself (can't save config by pressing Fn+F10). So I can also confitm that this is BIOS problem and not OS/software problem.
In my case problem also started after connecting external USB keyboard which has it's own set of additional buttons (w/o Fn, hardware buttons for PowerOff, Search, Home, Back, Forward, etc).
Problem was fixed once by removing battery and resetting BIOS to default but in 1 week everything started again.
Latest BIOS was installed before the problem appeared for the first time.

Issue might be related to external keyboard. But it might be not related to this.
Once keyboard is attached - nothing happens and Fn button continues to work. But after some time it stops to produce any output. Last time I had this problem after laptop woke up from sleep mode w/o any external keyboard attached.
