Hello everyone,
I have two HP 840 G5 laptops. One of them is missing the BIOS chip. The second one was fully functional — it powered on and worked properly.
I desoldered the BIOS chip from the working laptop, dumped its contents (I'm attaching the original BIOS dump from the second laptop), and flashed a new chip for the first laptop using that same dump. After this, neither of the laptops powers on anymore.
Now, both laptops have the same issue:- When turned on, the Caps Lock LED blinks 5 times,
- The CPU fan spins at maximum speed,
- After a forced shutdown (holding the power button for 10 seconds), the laptop turns off but then automatically turns back on after a few seconds,
- This cycle repeats endlessly.
What could be the cause? I flashed the same BIOS dump I extracted from the working laptop, made no changes — but after soldering it back, it no longer boots.
Could you please send the correct BIOS dumps for both of these models?- Laptop 1: M/B SPS: L15518-601, CT: PGWHT00WBBZ8QZ, SN 5CG9093W7B, Prod ID 2FA66AV

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,...
