IdeaPad Gaming 3 16IAH7 BIOS Issue / GPU Not Detected

[Deniz]

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 BIOS using the official Lenovo BIOS from their website, but it failed with a: “BIOS is incompatible” error.


Because of this, I believe the currently flashed dump BIOS is not from the exact same hardware configuration.

My questions are:

• Is it possible to modify this dump BIOS to match an RTX 3060 6GB configuration?
• Or could the initial BIOS clean process have been done incorrectly (vinafix, etc.)?
• I couldn’t find a proper cleaned BIOS / ME firmware for this model on the win-raid forum.
• Is there anyone here who can properly clean and rebuild the BIOS for this model?

I have attached to this thread:

• Original Main BIOS
• Original EC BIOS
• Alternative BIOS dump (boots but does not detect GPU)

Thanks in advance to anyone who can help.

Try, BIOS extracted from Lenovo website, DMI + Win key inserted

IdeaPad Gaming 3 16IAH7 - Type 82SA

BIOS ver. JMCN42WW
S/N MP2BR7D9
MTM 82SA0065TX
DMI 1000000-101FFFF
Win key 10AF000-10AF03F

The "ec.zip" is NVIDIA VBIOS for RTX 3060 Mobile PCI ID 10DE-2520 Subsystem 17AA-3AF6, it's good, matches one from techpowerup

Hello, thank you very much for your help.

I flashed the BIOS you provided and the laptop boots нормально now, the issue is solved.

However, you mentioned that I still need to insert DMI information and the Windows OEM key.

My question is:

How can I restore/write the DMI data and Windows key back into the BIOS?
Which tools/software should I use for this model?

I need to restore fields such as:

• Serial Number (S/N)
• MTM / Model Type
• UUID
• Windows Product Key (OEM)

Could you please guide me step by step?

Thank you again.

He has added the DMI for you already, go into the bios settings you should see the serial number and model .

Read BIOS chip again, main BIOS is 32MB, select correct chip model in your programmer software

The "EC" as you name it, is the NVIDIA VBIOS for RTX 3060 Mobile PCI ID 10DE-2520 Subsystem 17AA-3AF6, it's good, don't touch it (exact match with the VBIOS from Deniz, post 1)
