Hi!

You need to read your bios chip using hardware SPI programmer (read the first page of this thread) . Your bios dump not correct. File bios dump from Lenovo ThinkPad L440 must have size 8 193 KB.  

You need to read your bios dump from your bios chip again, may be multiple times and compare in any hex editor (for example HxD), all dumps should be identical.

If you will meet with some problems with read bios dump from your bios chip, then try to use different software version.

All software versions for Ch341A programmer I placed into this link:  https://files.fm/u/vchnhg37k

I recommend you use software AsProgrammer_1.4.1

But why do they share this on other websites?

Because on your photo Bios Password EEPROM Chip. It's not a BIOS chip.

So my machine is set with Bios Master password, I have to use limited User mode and it is hidden a lot.
What do I have to do to remove the password or use the hidden functions?

Hi i want to remove whitelist from bios Lenovo L440

I have the programmer but I don´t have the bios modified,  can u send it to me plz?

Each unlocked bios prepare individually and based on your personal bios dump. So, as first step, you need to read your bios chip using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post your file bios dump in this thread or upload it to any fileserver and send me the link.
