Hi all,

My Lenovo Legion Y540-17IRH is bricked—black screen, Novo button dead after BIOS corruption. The motherboard was upgraded by a Lenovo tech years ago (GTX 1660Ti to RTX 2060Ti). Here's the rundown:

- Full Machine Model: Lenovo Legion Y540-17IRH Laptop (Lenovo) - Type 81Q4
- Serial Number: PF1WV4BK
- Board Model Number: Couldn't find exact number—saw “FY710” near RAM slots, unsure if it's the full identifier due to the upgrade. Let me know if more is needed!

The SPI flash chip is a GigaDevice GD25Q128C (16MB). Using a CH341A programmer...

Hallo from the the other Carolina...
