Finally I've found the reason - the reason is a special version of ESET NOD.
I've spent so much time for to find that....
1 or 2 days of just decrypting of windows dumps... (that was are totally unuseful, btw)
I think it's not only for Lenovo, but for all notebooks (or desktops) with Win7+special version of ESET Smart Security Suit 4.
The reason why computer can't sleep or to do a hibernation with BSODs, etc. - dirty firewall module of ESET.
You need just uninstall ESET NOD32 Smart Security 4.2.40 and higher to 4.2.71 as minimum, or more fresh version.
Good luck and be happy
