    Thinkpad E15 20RD001FGE password unlock request

    Hello,

    I would need to clean out the password from this dump.
    I already saw in the forum that writing some zeroes starting from 0x3EF00 could do the trick, but just to be sure that I don't clear anything (MAC,..) unless absolutely necessary, I would appreciate you help!

    thank you!

    For the search engines:
    Mainboard nm-c421, chip IT8227E-256
    EC was dumped with SAS Jig (ioprogrammer). The 6.x firmware on the programmer only reads 128kB. On the homepage there is a March 2023 4.1 special edition rar, which flashes an 8.x firmware to the programmer. But this is not a SAS-firmware but a vertyanov one. You will get an error like
    ITE we do not respond!
    Check the connection and settings.
    MB powered? [CC_1]
    until you rewrite the ITE txt file and change LEFT to RIGHT, because the SAS board has the connector on the other side.

    Update:
    FFC "B - Two Side" also switches the direction, so no ITE txt edit necessary.

    SVP was cleared by zeroing 80bytes starting from 3EF00.
    No side effects so far.

        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:

        Thinkpad P14s Gen 4, BIOS Supervisor Password
        by badzymandiaz
        I have a laptop that was purchased second-hand, and I am able to boot Windows on and extract the BIOS dump (ONLY the BIOS region, I was unable to dump anything else due to an FCERR I received trying to dump the other regions) and use normally. However, because the BIOS is locked with a supervisor password, I am unable to use anything else except for Windows, and it has also disabled some hardware features of the laptop itself, such as the fingerprinting module, etc. that I really do wish to use.

        I have been digging around for nearly 2 weeks trying to find any mention of the same model...
