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

You have to determine if the programming is good and where it comes from.

The program is good as I can write another bios file and the laptop is booting.

But my real problem is that my nvdia mx150 is not detected after bios v1.21 update.

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
