  • @jbbankz   the last time I saw the reverting issue it was because of windows updates had downloaded the bios update and would apply at reboot if Windows update doesn't see it Installed. You can clear the Windows update cache and try to set your updates to not download over metered connections-- make sure you make your internet connection a "metered" connection under the network/update properties.  This was another reason why I went to Windows 10 pro instead of home. And run winaero tweaker to get rid of random Microsoft shenanigans including driver updates.

I have since restarted my machine multiple times and it has not reverted back to bios 1.05 but I will look into what you mentioned.  Its strange, since changing the bios and using Nerve Center with extreme cooling im getting a 20-30% increase in performance in my online multiplayer gaming.  Ill have to test some more games, as BF5 is my go to but i went from 80-90 frames to 115-130 fps.  I was quite shocked to be honest, although some of it may have to do with the recent overhaul of the game as their was a update yesterday. thanks for your reply.

i think there is an untrusted site which has bios 1.03 uploaded by someone, they say it's good but i don't trust it, not the site,but the bios, if it was good i don't think lenovo would actually make it bad,when it works they tend to leave as it is. but who knows, maybe they need new buyers.
