            Thanks. I see the error is due to graphics card error. Can you tell me how to disconnect the graphics card? I tried disconnecting a few coils and it turned on the screen but ran for a minute and then crashed.

                  post S/N, full name and model, motherboard model, TYPE,etc.
                  post the contents of the bios chip even if it is corrupted..

                      The bios chip must be unsoldered from the board before writing or reading..
                      do not use the clip, you may have errors..if you do not have anything to unsolder it with,
                      solder wires between the programmer and the bios chip..

                      you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

                          Need BIOS BIN for Lenovo Legion 5 15ACH6 Type 82JW
                          by JarJarBinks
                          Laptop was powered off during BIOS update. Laptop turns on, keyboards lights up, and then just beeps over and over into infinity until powered off.

                          Model: Lenovo Legion 5 15ACH6 Type 82JW
                          S/N: PF30P6DN

                          Attached is the BIOS dump from the laptop and the latest BIOS update from Lenovo.

                          I searched and I don't believe this particular bios has been posted. I attempted to the follow directions
                          on the BIOS guides page but I am brand new to this and the update file doesn't seem to match
                          the bios dump in size so I am at a loss on what to do to...

                          i used CH341a programmer to read the contents and followed the steps in YouTube to build bios.bin

                          can you help me fixing my laptop bios ? my laptop model is Legion 7-15IMHg05 (Lenovo) - Type 81YU (RTX2080 Super model) and last known bios (E9CN66WW)

                          p.s i have also uploaded the bios i extracted using my CH341a programmer if it helps

                          by hotcrossedbuns999
                          My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
                          1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
                          2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
                          3. I could only locate two chips that look like bios chips. Could someone verify this

                          🛠️ 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
                          ...
