L540: need bios chip location (photo) please

[glossywhite]

Hi there. Having trawled Google high and low for three days, I cannot find where the bios chip is located on my ThinkPad L540. I need to remove the whitelist by backing up the bios and patching the file, signing it and re-flashing the clean file.

If anyone could help, I just need the IC location, for the BIOS chip, as I’m not gonna strip it down until I know.

Many thanks folks. God bless you.

Look for a chip marked Macronix MX25L6473E or maybe a Winbond W25Q64xxx
No schematics unless you are willing to pay someone.
Maybe this helps: Lenovo ThinkPad L540 disassembly

PAY for a photo showing me where a chip is?

In case anyone else needs the location, here it is: https://photos.app.goo.gl/kWftxfjfvNt29N8PA

You need to pay for downloading a schematic.
Picture links are free, and it would be nice if they work (except yours, which does NOT work).
