Step 29
Remove the following 7 screws from the edges of the keyboard area.
Three 2 mm Phillips along the right edge.
One 4.5 mm Phillips underneath where the magnet was.
One 6 mm Phillips with a small head in the lower left corner.
Two 6 mm Phillips with large heads, one in the upper left corner and one in the middle

Step 30
Before you can yank the upper case off, you must disconnect the trackpad connector, the blue and white power cable, and speaker cable as described in the next steps.
Lift the upper case from the right side and use a spudger or your finger to disconnect the trackpad connector hidden beneath the white plastic tab. Due to model variatons your trackpad connector may be different from the one pictured.






When replacing the upper case, after you've installed your new hard drive, make sure you remember to RECONNECT the trackpad connector. I forgot to connect it when I put the computer back together, and had to take it apart a 2nd time in order to fix my mistake. Other than that I had no problems with this upgrade thanks to the detailed instructions offered here . Thanks iFixit.com!
