    • Pry up the right side of the palm rest.

    There are a couple of latches on the front of the palm rest which should be released before you move on to the sides. I think one of those latches is released in the picture above. The iFixit opening tool was helpful here, and I used some of the iFixit opening picks to stop the corner latches from closing while I worked on others.

    Cons of removing the WLAN card:

    o I found the screw in the last step very stubborn, worried about stripping it.

    o Takes time.

    Pros of removing the WLAN card:

    o Might make disconnecting the system board a little easier later. I had no trouble with the WLAN card in place though.
