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...
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...
