Hi Guys,

Anyone else using a Lenovo Legion Pro 5 16ARX8 (Ryzen 7945HX, 4070, 32GB RAM, 1TB NVMe) that upgraded to the latest LPCN65WW BIOS?

I upgraded through the Lenovo Vantage tool, and after that the system got completely unusable: The BIOS/UEFI will keep the screen jumping/garbled, and Windows itself won't load properly.

By sheer dumb luck I managed to change the system to "Discrete Graphics" mode and managed to get a proper image. I then wrote down the keys needed to do the same again.

Reseting to default and reflashing the latest bios also did not fix the issue.

I managed to downgrade to a previous version, LPCN59WW, which returned the laptop to a working state!

I then looked up a way to open a support ticket to make Lenovo aware of the issue, but to my surprise, I cannot submit a ticket through my account unless it's to send in the laptop for repairs.

I have attached a video of what happens with the latest bios.

Anyone else with this issue / know how to contact Lenovo for weird issues like this?
