    I followed exactly this volinakis guide and it's 90% accurate.
    I must write 00s on position 3. not FF because with FFs I got Error 2204 :System configuration data is invaid.
    Just an observation...

    Big thanks, volinakis!
    thank you for the precision of the 00

      Here is clear EC dump, you just need to program your EC chip (nuvoton) with Vertyanov programmer) and after that to fill all information like serial number etc..If you can't fill dmi block by Lenovo maintenance utility, here is adresses of these blocks
      Model name located at 0005C000

      SN,type and board number located at 00058000
      I don't have a Vertyanov programmer.
      Is it possible to add or change the boot order in the locked BIOS?
      The machine I have is fine, except it will only boot from the SSD; USB is locked out, so it can't be reloaded.

            unlocked KBC bin (Intel platform)


            for your information, password is stored bewteen address 0x5E000 - 0x5E200. I'm not sure if it is similar for other models. You can erase it with 0xFF manually also. 0xFF stands for empty memory byte

                      You will need an SPI programmer to make a full backup.

                        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:
                        • If I would buy this laptop and have

                        [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...

                        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....
