    A1502 820-3437 need BIOS

    Hello,

    I am working on a A1502 820-3437 that was water damaged.
    I need a clean bios please. My original bios is attached here.
    SN : C02N61KGG3QH
    I tried to clean the MERegion but each time it didnt work. Sometime the bios cleaned works for the first power-on with chime but after a restart it does not chime with no folder on screen. Sometimes the fan spins normally, and sometimes it spins and stops in a loop.

    Question :
    -what does it mean the mouse activity ?
    -Is there a manipulation to do before supplying the board ?
    -Why, with my modified bios the first starting chimes and nothing on the next ?

    Thanks a lot

                  🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
                  by macabook
                  Hello everyone,

                  I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
                  🧩 Initial Issue
                  • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
                  • External display (HDMI) shows
                  ...

                  [Problem/ Request] Bricked TongFang GK7MRFR BIOS
                  by cr4zychriss
                  Hello everyone,
                  I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
                  I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

                  ASUS Zenbook Pro Duo UX8402ZA BIOS
                  by pirati
                  Hello everyone,

                  I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

                  When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

                  I decided to try flashing a new BIOS, but since I didn’t want to desolder...

                  I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
