          Bios + DMI . If it doesn`t work check for loose ram slot pins

              DMI is not at the right offsets.

                  Unfortunately none ot these bioses didn't work for me. Pins in ram slots and also ram chips are checked and good.
                  Is there antything else to check, or APU is dead?

                      You can try a few older bios versions. Read the guides and you can find and extract them yourself

                          by kenkaniff
                          Product Name: HP Pro x360 Fortis 11-inch G9
                          System BIOS: U94 Ver.01.08.00 10/06/2023
                          Serial Number: 5CG31946F5
                          SKU Number: 85W05EC#AK8
                          Motherboard: ANOLE10-MV-TRIPOD / 6050A3332901-MB-A01 / 2021-11-09

                          This motherboard has 2 similar chips. One is on the front marked with BIOS SKT "Winbond 25Q256JVEN" and one on the back marked with U351 "Gigadevice 25B256EYIG". I ignored the one on the back and only desoldered front chip. Made a backup, made sure the reading was the same with another 3 backups.

                          🛠️ 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
                          ...

                          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,...
