Companies lock things down for various reasons. Some might call it wrong/selfish but from tech support standpoint i guess they want the least amount of issues to deal with when you call in for help. Considering these are budget class machines for the most part so is the Lenovo tech support. Also for instance the 7260 AC card has sleep issues so there might be some underlying reasons they blacklist things like wireless cards and maybe something they could not resolve or did not feel the need to so they lock it down. It sucks but thankfully people like SVL7 exist to help get around some of these issues IE downgrading. I ended up going back to 3.05 and the stock 7260 N card because of the lack of a working sleep but others would rather have faster wifi then sleep working so its good there is some choice.

It was with both my Logitech cordless mice. So one has a unifying receiver and the other does not.

The bios screen is the one you want for the revision you have. I downgraded to 2.07 and then white listed my BIOS for the 7260AC card but the machine would never sleep using my logitech wireless mouse plugged in, and i tried every suggestion to get the sleep working properly like disabling bluetooth etc but nothing worked so i rolled back to stock 2.07 then i used this posted version of 3.05 and it worked fine just in case someone wants to use this posted BIOS and fears it might not be legit. I took one for the team so to speak . And seeing the guy below my post also had success should reassure anyone that either wants to upgrade to 3.05 or go back to 3.05 that it is the real deal. I wish sleep worked along with the AC card i bought but i decided sleep was more important then faster internet speeds since i tend to open and close my laptop alot and use it unplugged . I do not think 3.05 will ever be moddable based on the posts ive read so yeah some tough decisions have to be made i guess on which is most important.
