    X270 - Bios flashing help

    Hello everyone,

    I am still a beginner and want to learn more about flashing bios. First of all, thank you very much for the tutorials made on this forum it helps a lot.

    Lets get straight to the point. When I try to flash the bios of my Lenovo X270 it restarts several times and always returns to the bios that was there at the beginning. When I get the bios from someone on the forum and write it to the bios chip, I always have the same serial numbers. I have the feeling that the pc is reflashing itself. Where could this come from? How to avoid this problem?
    Do we agree that when I write another bios on the chip I'm supposed to see another serial number in the bios? I even tried to write a bios with an administrator password on it. When I solder it back to the motherboard and turn on the computer I end up with a bios without password and the serial number always remains the same. The only noticeable change in the bios is the version of intel me that does not appear when I write a bios without cleaning me.

    Thank you.

      these variables are stored in the ec bios not the main bios, so is the password

          novice user attempting first BIOS write on ASUS laptop
          by alphabetty
          Hello first post!


          Ok so after an (ASUSTek) optional Windows update, my old ASUS E403NA laptop rebooted and froze in the BIOS menu screen and was unresponsive so after about 30 mins I powered off and back on again. Now i just get a power LED and a black screen, I have tried all the basic suggestions and all the suggestions on the ASUS site, spoke to ASUS support who said I will need to pay for an RMA.

          The laptop is worth €50 so I won't be doing the RMA at god knows what price.

          So I have seen some videos where people have reprogrammed the BIOS...

          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
          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....

          Summary of BIOS Whitelist Removal Problem


          Problem:
          I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
          Initial Findings:
          • My current BIOS version is N1KET58W (1.45).
          • I have a CH341A programmer and have successfully created two full backups of my BIOS.
          • I have the ability to use command-line tools on a Linux machine.
          Troubleshooting Steps & Conclusions:
          • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.

          Flashing ASUS UX51VZ with correct bios
          by Flyview
          Hi!

          Happy to be part of this forum for my first post!

          Short story:
          I believe my dad's UX51VZ has an incorrect bios (v207) for a UX51VZH flashed onto it. I'm not quite sure what the differences are between UX51VZ, UX51VZA, and UX51VZH. The serial number of this machine is D5N0CY845932229 and comes up as a "UX51VZ-DB103P" when checked on this ASUS website. All of the bioses can be found at this ASUS website.

          1) Do I have the correct bios or should it be the v205 for UX51VZ? Is there something I can check inside the machine to make sure?

          HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
          by Bloodhoundje
          Hi everyone,

          I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

          I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

          After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

          I have desoldered the bios chip (GigaDevice...
