Initially I observed the bios have been program by another repairer before

I have nothing to do, the new bios file you have but the DMI key is gone.

[Zickko10]

You already have the new file, but where is the original bios file ?

Hello. I am having a black screen of death with my notebook.
Whenever I try to turn the thing on, it turns a really dim black light on the monitor but nothing shows up & all peripherals dont work. (Keyboard/HDMI Output ect.)
I figured it can definitely be a bad BIOS & I am certain Lenovo did efff my notebook by itself.
& I was right in my presumption. I read through the different posts in here and I found my solution from post #29.
I have backed up my faulty BIOS & applied the posted BIOS and until now everything is working pretty much faultlessly.
Was wandering, if I wanted to insert every other unique features to the laptop, can someone help me on getting all the SN & other unqie stuff?
I have used a cheap CH341A USB Programmer but with the modified version so it read 3.3V (from the Youtube video).

You`re welcome,happy to help

The newbios you posted looks ok,the DMI is the same as your backup. You must flash newbios.bin with an SPI programmer .

Thanks so much for checking, ok perfect I thought that by doing this I could flash the file directly with the WinFlash64 program.
I flashed the file with the programmer and it worked.
Thanks for your help and guides!

Hello everyone,
I'm a newbie with bios and I initially flashed the bios from post #14 and then I wanted to try to restore the serial number and model number which were invalid so I followed the guide but I'm not sure of the result.
I'm also not sure because if I try to flash the newbios.bin file I get the following error: "ERROR 233 - Only secured capsule is allowed on a SecureFlash system!"

Could someone more knowledgeable take a look at the files?
Thanks in advance
