          This Compaq is not manufactured by HP. It is a Chinese model renamed with the brand. Like Gateway USA... but this is a Compaq Argentina.

                I didn't read the ec, only the main. I don't have tweezers, I would have to lift the IC and I don't want to manipulate the equipment too much.

                  What part number is the EC chip. Does it have an external EC rom chip or can it be programmed through the keboard connector or JTAG .

                      [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                      by zenius
                      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,...

                      TONGFANG "GM7TG7P" Bios Password Problem?
                      by traxformania
                      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...

                      HP Omen 15-dh0052nf power-on & bios password
                      by Nopslide
                      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....

                      How to Decode BIOS password for RedmiBook Pro15 2022 6800H

                      1. I bought this laptop from flea market, and the seller said that he had never set a password, however here is a password required when pressing F2 to enter BIOS.
                      2. And after entering incorrrect password 3 times, there is no any useful information like "recovery code"
                      3. I used universal bios backup tool, and dumped 8MB bin file, but hex code after "SystemSupervisorPw" is...
