        First boot press F10 reset bios to factory defaults save & Restart, 2nd boot reset security settings to defaults.
        search here bios config utility in forum in case you don't know.
        Use BCU to fill these DMI INFO​

                you need an SPI programmer..here is a video as an example...https://www.youtube.com/watch?v=DWWigscuQDY

                  Thank you for your reply, so in order to clear BIOS admin password, I have to:

                  1. Buy this toolkit
                  2. Use it to dump BIOS
                  3. Paste BIOS dump here with laptop information
                  4. Get the patched BIOS dump
                  5. Upload back the BIN (don't know how, btw)
                  6. Use DMI tool to re-input laptop information

                  Is my understanding correct?

                                        Hello friends.
                                        I have an HP Probook 455 G9 bios password, I tried the ones on the forum but the password was not removed.
                                        I am sharing my original files. I would be very happy if you could help me. Thank you in advance.

                                            post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

                                          [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?

                                          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,😇😇😇
                                          I need help unlocking the BIOS password on my HP ProBook 11 G2 laptop.

                                          🔒 BIOS Status: Locked with password

                                          The laptop is no longer under warranty and HP refused to help me.
                                          I’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!🙏🙏🙏...

                                          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....

                                          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...
