Reupload 2x missed packages to flash as new BIOSFor those who need a clean BIOS (no passwords, factory defaults, without DMI) for the HP EliteBook 840 G5 (6050A2945601-MB-A01):
Since nobody here could help me, I turned to Wrong Chip on YouTube (link below). Here's my experience for others facing similar issues:- These BIOS files work—I successfully flashed both by CH341A (modded from 5V for 3.3V!) by Neoprogrammer on Windows:
- 32MB chip (W25Q256JVEIQ)
- 16MB chip (W25Q128JVPQ)
- My W25Q256JVEIQ BIOS was corrupted (physical damagel). You can use my files, but they do NOT include DMI data (you have mine attached for serial 5CG013DSCM)
- DMI Solution: Wrong Chip provided my DMI data, which I injected using the method shown in this video:
- HP Manufacturing Program Mode | WHY it Happens & How to LOCK it

- HP Manufacturing Program Mode | WHY it Happens & How to LOCK it
- Boot Failure? Another reason my laptop wouldn't turn on was accidentally removing the 22-ohm resistor. If your motherboard is unresponsive, double-check all resistors!

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 everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight

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.
