Hello!
My MBP PRO 15 Mid 2015 with AMD R9 M370X doesn't boot after disable automatic graphics switching off. Immediately after disabling switching it froze, then I rebooted it and it no longer boots. When I turn it on, there is a power-on sound and fan noise, but the screen, keyboard doesn't work and apple logo doesn't lit.
What I have tried:
SMC reset (no reaction at all, i suppose because of keyboard)
NVM RAM reset (no reaction at all, i suppose because of keyboard)
Detaching battery and holding power button for 30 secs (doesn't work)
Reattaching SSD (doesn't work)
Seems like it is discrete graphics card failure, but before disabling automatic graphics switching off my laptop was working fine. And i worked with high intensity graphics apps sometimes, so i suppose discrete graphics was working too.
Is there any ways that i can try to boot it, disable discrete graphics off without booting, or reset it to factory settings to use integrated graphics when boot?
