Hello, I have a 2FA56AV (i7 8550U + AMD RX 540) with bricked bios (no image, 5x CapsLock LED). I have since flashed different BIOS (both 16 and 32M) but the AMD GPU and touchscreen are not detected by Windows nor BIOS menu.
Can somebody please repair my original BIOS or provide working one from the same model so all the components work properly?
I cant find the proper bios anywhere.

Okay so I fixed my BIOS by replacing the first half of the 32M file with data from another BIOS downloaded from the net. This way the GPU is detected and everything works properly.
I found out there is no touch on my laptop, the screen was probably replaced with no touch one.
I am including both 16M and 32M dump files that work and also support the AMD GPU. It should work on models 2FA50AV, 2FA52AV, 2FA54AV, 2FA56AV and 2FA58AV.
I have also cleaned the ME region for others to use, but did not verify if it is working.Comment

Hi. I had a similar situation with the touchscreen. It did not work until I added all the information, serial numbers, feature byte from the sticker on the back of the cover. This can be done when the bios is in engineering mode, or with HP BIOS Configuration Utility (BCU)Comment

Greetings badcaps community,
I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.
Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.
I have a Elitebook 820 G1 and a Elitebook 840 G2 here.
These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

Hello,
I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.
I assume the BIOS update failed, so I searched for the BIOS chip.
I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.
However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
