Hi, yeaterday i started my laptop and it was black screen no backlight nothing and tried a external monitor also no nothing .
Took it to a local store since and he said it's a motherboard issue and it is not worth fixing i think what broke it that sometime i let run in my laptop bag. I tried almost all solutions avaliable in the internet,but i found a method that may get work by reballing the gpu and im consider heating the motherboard and some people report that suffocating the laptop for 10 minutes worked for them. The problem is i have apu gpu and discrete one can i boot from the discrete one or do i have to go through extreme methods?

Thanks.

Laptop specs:
cpu: amd apu 4455m
Gpu's : 7500g + 7650m
Ram: 4 gb
