Tried to do so, but when I entered BIOS, it's turned already
But the good news, I have managed to update the bios to v41.
This is what i did:
- Extract the BIOS file,
- On the extracted directory, you will find a file platform.ini
- Open the file with text editor and go to line 467 and set Flag=0, so that it appears like this:
- Save the file
- Run H2OFFT-W
The BIOS installer will run as usual after this without prompting error.
In my case this works for me, but I can't guarantee if this will work on others.
So if any of you guys want to try, I take no responsibility for the result.

The password for 6KCN38WW_X64_SMT.zip is an extremly likely guess, especiaIly if you know the manufacturers name. In fact my second try was a hit.
Nevertheless I haven't tried to update to 38 or 41 from my "classic" bios 30 yet.

For the classic version the ram speed was changed from 2133 to 2400 with bios version 30. Furthermore there were some video issues and some throttling issues when running on high load for a longer time with previous versions (i.e. before 30).
Can you please report about ram speed, video performance and throttling after going throug the update procedure from classic to 41?
Details are on page 4, 5 (ram speed) and 7 (throttling) of this thread.
Thanks in advance!

I see the RAM Speed is 2400, and didn't find any issue on the video playback at all.
For the last case I need some time to test it. I will get back to you with result as soon as possible.

Thanks for your fast reply.
May I also ask, which classic bios version you were using before starting the upgrade to 41? I suppose 30?
Thanks once again!

I didnt get a chance to geekbench, but instead I tried to stress test CPU for some time, and yes there is throttling there as i can see the score go lower time to time.
I was using version 30 BIOS and now am using 41 version. The procedure given makes us go back to version 27 and jump to 29 and last to 41.

Thanks once again for your efforts.
I was asking for your initial bios version because the initial poster received the guide for a machine still being on 29. So I wanted to make sure it also works on machines that are already on 30.
With the other questions I wanted to make sure that 41 is running as well as 30 on my classic machine as we still do not know the reason for the two different lines.
Does anybody know what the security issues are that were fixed in 41 but not in 30? I have not found anything searching.

It took a while, but I’ve decided that there is no point in updating the BIOS to V41 after V30 (In my girlfrend’s 720s case the update to V30 along with installation of the newest AMD drivers from Lenovo Support site was sufficient - no throttling and video playback issues so far). I see that you guys are not giving up What is funny - Lenovo helpdesk has actually provided less straight forward solution to our problems than the official website with V30 BIOS update.
After reading the patch notes for V30 and V41 I wouldn’t bother to patch BIOS to V41 (provided that V30 contains everything up to V41)
EDIT: I could easily call Lenovo again and simply ask about both BIOS versions update paths if you Guys are just as curious as I am.
