    I took BIOS u72 as a basis, added part of update 1.04 to remove the image (screen saver when turning on). Then I figured out how to read the DMI zone and, using the HP BCU utility, wrote all my information and exited the BIOS editing mode.
    Thank you very much for the tip.

        Hello everyone,

        I have an HP ProBook 450 G9.
        I need to remove the administrator code from the BIOS to reset the PC.
        I extracted the BIOS chip dump, but I don't know if this is the correct chip to take the dump from.
        Serial number 5CD3091R26
        Thank you in advance.

            Hello again
            I forgot the motherboard number DA0X8SMB8H1 REV: H. I have a doubt about the dump!!!
            For the dump, I copied it from the top chip, not the EC.
            Thank you.

                    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...

                    Hello,šŸ˜‡šŸ˜‡šŸ˜‡
                    I need help unlocking the BIOS password on my HP ProBook 11 G2 laptop.

                    šŸ”’ BIOS Status: Locked with password

                    The laptop is no longer under warranty and HP refused to help me.
                    Iā€™m looking for a custom SMC.bin file.

                    I don't have a CH341A programmer, so it's difficult for me to provide a BIOS file.

                    Thanks a lot for your help!šŸ™šŸ™šŸ™...

                    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....

                    Should I buy a Lenovo Thinkpad E495 with bios password?
                    by RMDUiFT
                    Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

                    I have a few questions:
