Hi Everyone.

I have been trying to fix a naughty lenovo laptop.
Laptop come to me as not booting or ginving picture. So I have cleaned the ME on the BIOS and it come to life, but here is the tricky part:

have a Lenovo V15 ADA05 laptop that fails to power on. I've already tried several troubleshooting steps, including replacing the RAM, running hardware tests, performing a BIOS reset, and even reflashing the BIOS firmware.
When I press the power button, the power LED blinks briefly, the fan spins up momentarily, then stops — and the system remains unresponsive with no display output.
What could be the potential cause of this issue?​

Hello good day. Long story short. i unlocked the bios using SREP and switched the setting "Special display features Enable/Disable HybridGraphics" from "HybridGraphics" to "disabled"

this has bricked the laptop. it does not boot on internal or external display...

i have tried flashing known good roms from both lenovo and other forums and reflashed it to the chip.

but still no boot. the device turns on and cpu heat's up. but no post/boot.

I have attached the dumped corrupt bios.
