Hello I have a Lenovo Y540-17IRH and I would like to get access to the advanced section of the BIOS. Could you help me unlock it?

Link to BIOS installer: https://download.lenovo.com/consumer/mob...cn42ww.exe
Link to BIOS file: https://ufile.io/jrmberts
Link to extracted BIOS file (using InsydeImageExtractor): https://ufile.io/ng66o4ut

In order to flash the modded BIOS file (that you'll give me), I'll need a SPI-programmer+SOIC8 clip. Do you have a tutorial on how to use one and what to do?

Thank you

Hi, I have a Legion Y540 i5-9300H + GTX 1650 Model Laptop.

I was able to unlock the Advanced Menu in my BIOS but there is a special OverClocking Menu that looks like this (see image below). It is greyed out on mine. I cannot unlock it.

Here is the Dump File : https://drive.google.com/file/d/1Bcamha9...share_link

Please Unlock the OverClocking Feature


Thanks

Hi,

I'm the user of a Legion Y540-15IRH with BIOS version BHCN42WW. I already used an CH341A programmer to dump the BIOS that is attached to this post.

Currently I'm at the same situation as $asparkoffire$ was. I already unlocked the advanced settings menu, but I would be really grateful if someone can help me to enable the "Overclocking Feature" at "Overclocking Performance Menu".

Thanks for your Help.
