working keyboard and trackpad again unfortunately kept the battery out it was bulging.. I also put minimum screws back in 4 in back one on each side and 2 in front. I will look for a bottom case screw kit for my macbook. I get to take it all apart again for the new bluetooth 4.0/wifi card I bought. This new card will give my macbook pro the capabilities of the newer models, handoff, continuality and airdrop
