Hi,
First of all, I need to tell you this, my laptop is actually Dell 7520 but my bios chip was corrupted (beeping) and they replaced it with 5520 chip. Everthing works fine but except switchable graphics. When I install AMD driver, both my cards are disabled. Like I never installed their drivers, I can't use them. Anyway, I did some research and I guess I can fix this issue with unlocked bios by changing them manually.
BUT if we can change my current bios software with 7520's bios software. I think that would be the best solution but I am not sure if we can the main bios chip software.
What should I do for the best solution? And how can I get the neccessary infos of my current BIOS software to provide you?
