Just need a small phillips screwdriver
First remove screws that hold on back covers. Do not worry about taking them all the way out, there are special clips that hold the screws to the cover so they do not get lost.
Pull the covers off.

There will be three screws underneath the covers approximately where I marked the three blue X's that you must remove to remove the keyboard.



Once the three screws are removed flip the laptop back over and open the lid. The keyboard will easily lift out.
On the back of the keyboard there is a flat ribbon cable that must be slid into the slot on the main board. Push the brown clip down to lock the ribbon in place.
Lay the keyboard back down shut the lid and flip over and put the screws back in.(In reverse order)
