Hello everyone, I own a Legion 5 laptop equipped with an RTX 3060 and an AMD 5800H. I need to share the issue right away so we can address it quickly. The Nvidia GPU was already damaged, but initially the system booted using only the CPU. Unfortunately, after attempting a VBIOS flash with a lower TDP than the GPU, the laptop stopped working altogether. When powered on, the screen stays black, it powers off and restarts two or three times, and the fans run at maximum speed before shutting down. I’m considering giving up, but I’m curious—can there still be a chance to get the laptop to boot in some way without having to replace or desolder any motherboard components?

Welcome to the forums, newcomer! I understand you're considering disposing of the laptop, but you're curious about the chance to get it to boot at least partially without replacing parts like the motherboard components. You'll need to reprogram the BIOS using a CH341A BIOS toolkit (to restore a previous version) so your laptop and iGPU can function. This works best if the BIOS is still intact, not damaged or completely failed. Ideally, you should have returned the device through RMA if it was under warranty.
