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

Please reprogram the original bios to determine it is working before making any other changes.

OK,
I start over again.

My problem is I lost my Nvidia MX150 after updating to V1. 21 bios.

Even after I update my bios to 2.02, MX 150 also not detected.

I have read acer forum and found that the BIOS V1. 21 has VBIOS of MX130 and flashing with it had override my MX150.

so my problem is, can u make bios file that can detect my MX150 graphic card

Thank you
