I've exported the newest bios for 15 ihm05h. Can be the advanced setting be unlocked? Could anyone share me the howto, of help to have the current latest BIOS in unlocked state? I have an usb flash programmer for worst case but don't know which chip will be bios chip... Big Grin

I done the following guide to extract the bios from the lenevo's flasher app

- Create a new folder (eg. bios), then copy Bios.exe and use 7zip to extract the dependencies innoextract, InsydeImageExtractor, UEFITool into it.
- Open cmd and change the current directory to the folder you created. (eg. > cd Desktop/bios)
- Run the command > innoextract Bios.exe
- Open the newly generated Bios.exe in the app folder with 7zip as archive, and then extract the files from the archive.
- Copy extractor.exe, msvcr120.dll, and change the current directory to the app folder.
- Run the command > extractor Bios.fd out.fd

Thank you in advance

Hi, hope you are doing well. 
I am looking forward to enable the correct speed on my Lenovo RAM to 3200mhz as opposed to the locked 2933mhz.
I would require access to the Advanced BIOS settings that are currently locked. 
No tools I could find worked. 

Could you please guide me on how to provide the information you need in order to do this? 
I could not find the information. 

Looking forward to hearing from you.  

PS: I do apologise but this is my first time posting and having replaced my RAM thought everything would work fine.
