    HP ENVY x360 2-in-1 14-es0013dx BIOS request
    by Chris2025
    Hello BIOS gurus,

    Laptop in trouble is:
    model: 14-es0013dx
    ProdID: 7H9Y4UA#ABA
    SN#: 8CG35112PL

    Current issue: laptop turning on, battery charging, fan turning on/off, CAPS LOCK react on pressing but screen remains black.
    What was done so far - connected external monitor via HDMI, system reset, BIOS reset and BIOS recovery attempted as per HP recommendations - all to no avail.

    Would it be possible for one of qualified people here to cook BIOS binary file for this machine?

    Thanks in advance!...

    ASUS TP500LA BIOS request/repair/merge?
    by jbonavita
    Hi, my laptop wont boot at all
    With original bios no POST, only LED lights
    With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
    Some issues
    A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
    B- If updated from 500LN version 203 to 300, the battery stops being recognized

    Things I tried

    1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

    [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
    by zenius
    Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

    Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

    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....
