Its strange though, because the keyboard does work inside the bios menus...

I just used lenovos bios update software and the peripherals still do not work.

I read back what the Lenovo tool flashed with my CH341A & found quite a few differences from what was flashed onto the chip by the working bios you linked from badcaps.com.

I have attached the bios I dumped from what Lenovo flashed if you could take a look.

This is so strange that even after flashing the official bios from Lenovo & reinstalling windows and drivers, the keyboard and mouse still do not work.

You cannot download the file? Or cant see the differences?

Comparing the raw bin (not comparing modules within UEFITool), there are several hundreds of differing bytes beginning at offset 2EAC00 continuing through most of the bin.

I am comparing with the hex editor HxD which has a comparison tool showing hundreds of bytes difference.

It's natural because compression is used. The only correct comparison option, in my opinion, is bulk comparison of modules.

Oh I was not aware that these 4mb files are compressed. Regardless, I am still stuck in the following situation:
1) Flashing any of the patched Bioses produces a brick
2) Flashing any of the non-patched Bioses allows the laptop to work fine, excluding the keyboard and trackpad which are completely non-functional within the OS, though work fine while in the BIOS menus.

I want to sort out the first question first. It is simple to determine whether the problem with the inability to boot into OS is caused by my changes or not. You are comfortable with the hex editor, so I think it will not be difficult for you to change the BIOS a little. For example, the name of a setting. My point is that maybe even 1 byte change creates an inabilty to boot. If after some insignificant change the same thing happens. It will be possible to say for sure what the reason is.

I was able to modify the following module: LenovoSetupMainDxe.efi
See linked for the change: https://m.imgur.com/a/xxxERcE
As you can see I changed the word Embedded to ENbedded.

I assume this rules out the possibility that the entire BIOS is protected by some encryption?

Right. Now we know that the menu module can be changed freely.
But then why can't I made BIOS mod to work? Maybe I shouldn't have deleted all those dummy settings in the module?
I redid everything again.

That BIOS worked! As you can see in the following link, the advanced and AMD tabs are now accessible:
https://imgur.com/a/99w2zjm

That takes care of one problem, though unfortunately the trackpad and keyboard still only function while inside the BIOS menus. As soon as I boot into the operating system, both devices are disabled and the only way I can interact with the laptop is with a USB keyboard and USB mouse.

I have played around with the BIOS settings related to the keyboard/mouse, and have even resetted the CMOS, so the issue doesn’t appear to be related to any BIOS setting that is currently accessible to me.
