Did you set up your raid?? If you are running the 2x 128GB SSD's then you might need to configure your raid before installing.

No I mean by playing with brightness up and down it wakes my monitor up. Normally If I leave it to sleep, the laptop screen comes on but I lose hdmi connectivity. So I play with brightness up and down and it wakes my external screen up. Humbug but it...

Sorry for this possible late solution. I was having the same problem with my g750jh and I can wake my monitor by pressing fn+f6. Hope this helps.
