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

Attached original bios from this website

And my bios dump for your reference

My problem start when I flash my bios with v1. 21. And then my MX150 is not detected. I updated to v2. 02 as they say it has new vbios. Mx150 also no detected. Then I downgrade to V1. 20. Still mx150 not detected.

I prefer and like to use bios v120
