My track pad quit responding and seemingly had a mind of it's own.
I went to Ifixit website and found a great pictorial manual on the steps and tools needed to replace it. In doing so I ordered a Tri-wing Y0 screwdriver which was delivered in days. Followed the steps and replaced the track pad. Works like new! Thanks!!!
Google "how to..." before beginning any repair on your computer. You typically need tools you do not have! Attempting to replace parts without these tools is foolish and would probably result in damage.
