    Yoga 520-14IKB missing information in BIOS

    It is missing

    *Product Name
    *MTM
    *Serial Number

    Just shows INVALID behind them.

    How to add that information? ThinkCentre/ThinkPad tool doesn't work on Yogas.

    And bios has some unusual structure for me.

          The file I have in first post is the one I got from the laptop. So that is as original as it gets.

          I have the information I need to enter on the sticker but no idea where to enter it.

                  Thinkpad X1 Yoga Gen 3 ,How to know if the BIOS is corrupted
                  by Loki_Fido
                  Hi everyone, hope everyone's having a great day.

                  I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
                  I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.

                  So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
                  Does this mean the BIOS is fine? making it a hardware issue?

                  I downloaded fresh BIIOS from the Lenovo site and used Hex Editor replace the Lenovo's BIOS into my BIOS region. But the file size ended up being...

                  Lenovo Yoga X1 Gen4 - Faulty Bios or what is going on?
                  by AYsys
                  Hello dear forum members,

                  I own two Lenovo Yoga X1 Gen 4 laptops. One of them had a touchscreen problem, and I tried to fix it by externally flashing the BIOS. Unfortunately, I didn’t save the original BIOS and accidentally flashed it with a faulty one. After that, the device stopped working completely.

                  I then had the idea to make a BIOS backup from the other Yoga X1 Gen 4 (same hardware) and flash it onto the non-working device.
                  Nothing was flashed here — the BIOS was only backed up.

                  I created the backup using a CH341A Black programmer and NeoProgrammer....

                  Lenovo Yoga Slim 7 14APU8 Bios Request
                  by beogeek
                  I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!

                  Attached is the bios dump in the state I received it...

                  Help needed in unlocking BIOS Supervisor password - Lenovo X1 Yoga 5th Gen
                  by baaligoga
                  Good day, everyone!

                  I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.

                  I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the...
