Your steps and instructions were perfect and provided the guide I needed to replace the CPU fan. I agree with the other commenter that there were a few additional plug connections that had to be disconnected but they were very obvious and easy to do. I actually drew the picture of the bottom of the notebook with the screw locations on a folded-over large piece of cardboard. Each screw I would sink (punch) into its location in the picture. It worked great. Thank you so much for your time and effort to help us all! We owe you.
