Hi Guys
Trying to repair a Lenovo Ideapad3 Model 15IAU7. Getting power light bit no signs of life. I can feel the CPU heating but, But no display or fan spin. Hoping it's just a corrupt bios. There are 2 chips on the motherboard, i usually desolder the wrong one first lol... so i went for the bigger capacity one this time.
Ive attached th bios file which was read ad verified after removal from the motherboard. I would be greatful if someone mor knowlegable than me can take a look and repair or possible supply a clean image. also advise if i need to add in any blocks for serila number etc... into new clean image
As always much appreciated
Thanks in adanceComment

Hello everyone,
I have a Lenovo IdeaPad Gaming 3 16IAH7. When the device first arrived, there was no display at all.
I had the BIOS cleaned, but the issue was not resolved and there was still no image.
Later, I flashed a different BIOS dump from the same model. With this BIOS, the device boots and display works, but the GPU is not detected in the BIOS (RTX 3060 is missing).
After that, I tried to update the... -
Dear all,
I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.
Here the steps I have taken to fix the laptop:

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

Hello everyone,
I’m working on a Lenovo IdeaPad XiaoXin Chao7000-15ARR (Ryzen platform) and I need some help with BIOS reconstruction.
Unfortunately I only have the bare motherboard (no original chassis, no sticker, no working system).
The laptop came with black screen.
What I have:
- Original SPI dump read from the board (W25Q64DW 1.8V, 8MB)
- Official Lenovo BIOS update (.CAP file)
- Photos of the motherboard (front and back)
- Board powers on, but with original dump it stays black screen
What I tested:

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- Barebone / Chassis: TongFang GK7MRFR
