I have a Toshiba Satellite P75-A7200 how do I remove the keyboard? It doesn't look anything like my old Satellite L505D.
To remove the keyboard, remove the battery, the bottom access panel and the hard drive. Remove all the rubber screw covers and screws (20+) on the bottom panel. Lay out the screws out on a flat surface in the pattern in which they were removed for easy reassembly. Remove the optical drive (and two more screws under it) then lift the bottom off of the main chassis from the front edge. There are two plastic clips under the #2 hard drive compartment and three clips on the back edge of the battery compartment that you may have to wedge a small screwdriver into to release the base. It should come off fairly easily. If not, you've missed a screw (or two).
TAKE A GOOD PHOTO OF THE INSIDE OF THE LAPTOP TO ASSIST IN REROUTING THE CABLES.
Remove the four screws from the fan and motherboard. Remove the speakers and CAREFULLY disconnect the cables from the motherboard, being mindful of where and how the cables are routed. Some of them just pull out, some have a 'flip' latch and others have a 'slide' latch. Remove about 18 screws from the plastic panel that sits on top of the keyboard; it will lift from the bottom and remove easily. The keyboard is now free. I may have missed something, so use common sense and don't 'force' anything off or you may break it. I hope this helps you. Good luck!
