    Hello. I have a problem with bypassing the bios password on the T470 lenovo, the CD: CT470 NM-A931 REV 2.0. I was looking for a bios feed, but I did not find one. There is also a password on the SSD drive, but rather I write it down. Please help. In the attachment, a bios droplet with a password.

    The password in this album is probably in the MEC.

    Tomorrow I will do another MEC dump and send. In total, I could take both discharges. Excuse me.

    Where does the 1MB file from Meca come from?
    Something's wrong.
    What is your layout ID, what programmer?

    Maybe I misunderstood something here. I've done a second bios dump called 25Q80JV

    So there is a problem. My TL866 can not read it. In addition, the MEC is rather dense with black epoxy.

    Again, "black clouds" over servicing lenovo!

    SVOD3 or Vertyanov JIG V3 give them advice.

    I do not think I will buy a programmer especially for this occasion. The laptop is my private one, purchased for part by this slogan, but I was hoping that another bios feed would be enough.

    I gave links, send a mail to them with the question about the possibility of: sending a programmed Bios bone.
    They were usually "kind"

    I have not seen the last ebay offers.

    The password is not saved in the BIOS only in MECU.

    And how does this method of downloading a password work for you? Have they mastered something for this platform?

    The latter Link (vinafix.com) (with a mug of beer) seems to have both batches.

    I have a friend who has an account on vinafix. I will ask him, he will download and check me. All in all, it's a good site, they only count. I think PLN 50 a month.

    Vinfix $ 10 per week. Ripples are not everything. Besides, they do not have to NM-A931.

Topic summary

The discussion revolves around bypassing the BIOS password on a Lenovo T470 laptop, specifically the NM-A931 REV 2.0 motherboard. Users suggest that the password is likely stored in the MEC (Microcontroller Embedded Controller) rather than the BIOS itself. Several users discuss the challenges of extracting the MEC data due to its dense epoxy coating, which complicates reading with standard programmers like the TL866. There are mentions of alternative programming tools and services that may assist in obtaining the necessary BIOS files or MEC dumps. The conversation also touches on the potential costs associated with these services and the availability of BIOS feeds for the specific model.
