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

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:
- downloaded latest BIOS from Lenovo Website... -
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 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

So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.
I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...10-11-2024, 03:12 PM -
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...
