    Cleaning the ME firmware should solve it, have you tried doing that before ? .There are some guides https://www.badcaps.net/forum/troubl...22#post1622422 and many youtube videos on the suject. It is something all laptop technicians should try to understand.

    i had a supervisor password, i read and saved the winbond w25q128fv with the elnec programmer as w25q128bv because it was the only one on the list.
    I tried with various files from this site but none works all the time black screen only for a moment when connecting the power supply the led on the button will blink (no beep).
    I uploaded back my original file and same thing. I'm doing a write verification and it's ok.
    Does anybody have an idea???
    Misread file or something else?
    I am attaching the read file

    Hello hoaca388,
    Please can you tell me how to merge original bios and bios extracted from lenovo downloaded exe file?
    From what hexadecimal address to what other address should I copy and paste?

    Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
    by Ahari
    Hi all,

    This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

    I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

    I...

    I need a BIOS dump for the Samsung S49CG934SU monitor
    by Habble7
    The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

    Suspected Cause:
    I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

    Troubleshooting Attempts:

    Lenovo ThinkPad L15 Gen 1 i7 (20U4) Bios and EC dump needed
    by Joluvillas
    Hi all! I was reading on tutorials how to flash a bios to remove password from a bios, and I ended up reading the EC chip instead of the main bios chip, it only gave me a .bin file of 1,024kb, I learned later that that is the EC chip not the main bios chip (I should have read the tutorials here instead before attempting anything, my bad), I went to flash the original backup, the 1,024kb size file into the same chip and laptop is not powering up anymore. I may have screwed the chip or even the motherboard (Hopefully not), I am trying to see if there is a fix before I discard it. I had a couple...
