    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....

    Lenovo ThinkBook 13s Gen 3 ACN ā€“ Need Help Fixing Corrupted BIOS (W74M12JW)
    by HumanDev228
    Hello everyone,
    Iā€™m working on a Lenovo ThinkBook 13s Gen 3 ACN (AMD Ryzen 5 5600U) with a Winbond W74M12JW 16MB BIOS chip

    Symptoms:
    • No display, fan spins, white LED blinking
    • Temporary boot after flashing another BIOS
    • Dies again after reboot
    • Current BIOS dump appears corrupted (mostly FF-filled, no valid UEFI structure)

    What I already tried:
    • External flash with CH341A + proper 1.8V supply
    • Flashed GMCN33WW-031F.bin (booted once, then failed again)
    • Reflashed original dump ā†’ same issue
    • Power reset, battery disconnect
    • RAM reflow attempt (no change)
