        Is there any way to program the EC without pulling out from motherboard?
        I am able to read it using T48 but I am not able to erase it properly.
        SVOD4 is not able to recognize it show " status register 1 0XFF " & "status register 2 0XFF "
        CH 341 is not able to provide enough current so does disconnect the programmer once I connect the wires.

              [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...

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

              šŸ”§ Model: HP ProBook 11 G2
              šŸ“¦ Serial Number: 8CG72478MY
              šŸ†” UUID: 6F5ED686-5532-11E7-A2E2-911C6404E011
              šŸ”’ 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!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....

              BIOS version: RMARB5B0P1010 20230628

              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...
