Anyone who can follow along with instructions can do it
I was drinking an iced beverage and the condensation on the outside of the glass dripped on the edge of my trackpad. The pointer and mouse was making the computer do things all by itself or not responsive at all. After a year of hoping it would dry out, it never did. So I got a replacement trackpad and replaced it myself.
I was extra careful and took extra time because I didn't want anything to go wrong. Now I have a perfectl working computer and I am so happy.
Just be thorough and make sore each step is followed to the letter.
