Hello, I am attaching two BIOS dumps from two HP EliteBook 840 G5 laptops - I was unable to reset the BIOS password using these tools:

Hey everyone,
I recently bought a CH341A programmer, but I’m still not 100% sure what to do next. I couldn’t find any tutorials specifically for the HP Elitebook 835 G11, so I’m trying to piece things together.
From what I’ve learned so far, the process looks something like this:- Use the programmer to read the chip.
- Save a backup of the dump.
- Open the .bin file in Hex Workshop.
- Replace certain lines with “FF”.
- Write the modified file back to the chip.
- Boot the laptop → password should be gone.
I’ve also heard that some systems have both a Main chip and...09-07-2025, 04:28 PM -
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,... -

Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.
My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).
Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....
