Thank you very much hoaca388 , with this file the laptop starts in "manufactured" mode (I guess that's how it should be?), after filling in the missing data in the BIOS, everything works as it should. I would like to know how to unlock the 32MB bios myself, but it's probably a secret?
Thank you again for your help and best regards

RCUnlocker can delete computrace lock? Sorry, this is my first time encountering this. The laptop was blocked for organization; the laptop was scrapped. I was able to fix it, it did not turn on, but I see a blockage when installing windows.

Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -
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,... -

I am very grateful to this community, as I have actually eeked out a living from buying salvage PC's & Macbooks and repairing them. So, thank you all in advance!
I have searched and found some useful information regarding my issue, but my case is a bit different than the info I'm finding. But if anyone here can give me any useful advice, it would be highly appreciated.

Hello,
I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).
But today it's not accepting my password. I'm %100 sure i'm entering the correct password.
I'm trying to reset my bios without success.
I tried :
-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries... -
