BIOS ACER A515G-51G-59Z0 CV501 LA-E829P

Hi, I'm having trouble with this laptop.
ACER A515G-51G-59Z0 CV501 LA-E829P. after bios update to version 1.21 Nvdia MX150 gone missing because of VBIOS overite with VBIOS MX130. I have upgrade tp v2.02 MX150 still not detected and downgrade to V1. 06 also MX150 not detected.

Maybe writing the original bios file will solve the problem.. I hope someone can help me.

Thanks in advance

Nothing wrong with my chip, It just not detected after bios upgrade to official acer bios V1. 21. Before that it just working fine..

100% upgrade Cannot cause this problem, you can contact Acer to ask. I have had this problem for over 20 years when I upgraded the BIOS.
