              It worked! however the unit is unable to boot into windows due to the security keys and bitblocker being enabled. can this be salvaged from the original bios?

                      I used bios from post #6 to test and it's working. But when I copy from old bios DMI (I tried area 0x00 522 000 - 0x00 524 000, or biger 0x00 520 000 - 0x00 524 000 ) It doesn't work (black screen). What area should I copy?

                                I think the problem was he added his DMI to the bios at post 6, and that bios has the Debug section (9C) .His DMI 7C ,the 2 don`t play well together.To copy his DMI to the bios at post 6 he would have had to include the debug section as well 520000 - 523FFF
                                .The bios at post 5 has no debug section as its a virgin bios,only the DMI needed copying to it 522000 - 523FFF

                                .

                                      Laptop still works. Owner said that probably motherboard was replaced earlier (so there is different SN on the cover). I tried to replace 520 000 - 524 000 before my post, but no screen, mayby I did it wrong.
                                      So for the future cases. Should I copy it all with LBDG, or do I need clean LBDG section everytime?

                                          by Wahaz
                                          Hello,

                                          I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                                          So I thought it was a Bios problem.
                                          I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

                                          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...

                                          Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
                                          by grimacelord
                                          Hello there.

                                          I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.

                                          History:

                                          1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.

                                          I searched for this error online and discovered...
