    Only bios and EC, your computer can't be opened with bios then EC is the only way. Or you can solder wires to the extra pins to see.

    So there is still EC chip, look for chips with number 128 or 256, for example: 25Q256VDS..

    Before I could enter the BIOS to apply the default settings, an error appeared stating that there was a mismatch and that information had been copied from the embedded memory. After rebooting, the BIOS is still locked.

    On the first boot, it showed a mismatch error and mentioned that it copied information from the embedded controller. After restarting, the BIOS is still locked.

    [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,...

    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....
