Re: Alienware M17x R4(7970m) Discrete Graphics Not Detected Upon First Boot
If you power the system on without connecting AC adapter, the system will work on integrated GPU to save power and increase battery life. You may Connect AC adapter to the system and press Fn + F7 button keyboard to enable the video card and restart the computer when prompted. The system is working as designed. For more information, you may refer to article Here.
Please reply if you have any further questions.
