@Steve Langasek (vorlon) I am a user your talking about, "least one user reporting it after only booting the live CD without installing" - it's about me (#100 post). @Anthony Wong (and his teammates) already contact me and with China Lenovo techics. At this moment my laptop is in hands of sertificated service of lenovo in Minsk (country Belarus for automated translate). In my case i am get prepared, that the only option is to replace my bios chip (or entire motherboard). I am not waiting miracle. The only desire of mine, is to be shure that my most preferred OS is not hurting hardware of any one. I saw #117 post. "I don't care postfactum" - it is not why we are all here... We are choosed to be more independent, to take more control of aur own deviсes.This is problem that we have to solve together. Not guided by thoughts like "bring my money back". And in ending of this topic - if it will be nessary, I am can to provide making test on my device. Even if they lead to its breakage... Thanks for attention.

It's not possible to save new settings in BIOS anymore and after rebooting, the system starts with the old settings. Moreover (and most important) USB booting is not possible anymore since USB is not recognized. It's very serious, since our machines do not have a CDROM. Lenovo forums at the moment are full of topics regading this issue.
