by SparoHi, I recently worked on this laptop and noticed there isn't an already existing thread for it
So here are the BIOS files I extracted from the Lenovo website, maybe it will help someone

by MoustickHello everyone,
I'm looking for a clean 16MB BIOS dump for the following laptop:
Model: HP Pavilion 17-cp2046nf Motherboard Board ID: 8A81 Motherboard codename: Eunice 22C2 CPU: AMD Ryzen (17-cp2 series – Barcelo-R / Rembrandt-R) BIOS chip: 16MB (SPI Flash – Winbond / GigaDevice, to be confirmed)
Symptom / reason for request: Laptop won't POST after failed BIOS update / black screen.
I already tried HP's official BIOS recovery (USB key method) without success.

After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -
by piratiHello everyone,

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...-

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...-
