Could you please remove white list and unlock advanced menu for my bios?

Maybe a new processor microde?
And 5 beep can be muted ;-) but not necessarily if it's a lot of work.

Thank you

For unlock your bios, as first step, you need to read your bios chip by using hardware SPI programmer.

Hi!

Your bios dump not correct. File bios dump from Lenovo ThinkPad L440 must have size 8 193 KB.

I checked your file bios dump, unfortunately it's not correct, it contain only symbols 00. 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, and contain correct data.

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

 

Also, check if you tried to read correct bios chip. See a photo below.L440-2.jpgL440.jpg

Which chip model are you trying to read? Which chip model do you choose in the program? Have you installed the drivers for the CH341A programmer?  Show screenshots of the program while reading, and a photo of the BIOS chip.

check pictures and short movie about bios https://drive.google.com/drive/folders/1c5dLNrHlGjOsQrxXPSG7Dfdsd56DHbjG?usp=sharing

and i tried all the programs ....

Have you installed the drivers for the CH341A programmer? If you open Windows Device Manager, you see: Interface -> USB - EPP...CH341A  ?

Also, don't use a USB extension cord.

same problem ,i tryed ... i found an old motherboard and i tryed to read bios from it , and that 1 worked ,auto detected and bios read corectly,i dont know why doesnt work on this chip :(

In this case, I think you need to try to unsolder the BIOS chip, and try to read it directly.

This backup file was made using the backup utility, and therefore it is not suitable for this case.
