I take it it goes apart same as G750.
First you have to of course take out the screws by the edge. I have 4 at the bottom 2 at the top and one somewhere mid on the left.
Then I take out the battery ones.
Then I take the bottom plate off and unscrew them (They're market with letters on mine)
Then you take out optic drive and unscrew screws there.
Then I take out the speakers.
Then I unscrew the keyboard.
Then you use card and jam it in to lift the keyboard and take it out. (Watch for keyboard ribons)
Then you get to the motherboard and unscrew those. A bunch of them everywhere.
After that I can take my MB out and take out the CPU and GPU plate wit fans.
Then you can unscrew the CPU and GPU cooling unit and that's it.
