Replacing any component in a laptop requires patience, strong organization skills, and a good work space. With enough patience and perseverance anyone can do it!

In order to successfully replace the dv7 cooling fan you need to work on a flat surface with good lighting and plenty of room to keep small parts organized so that the computer can be put back together without issue.

Make sure enough time is set aside to complete the process in one sitting. This project's estimated time frame is 4 to 6 hours.

WARNING: Before touching electronic computer components, such as the motherboard, CPU, or RAM, discharge all static electricity by touching a grounded metal object.

WARNING: Disassembling a laptop and replacing components by yourself often voids the warranty. Handle all computer parts with care, and be patient.

My HP Pavilion dv7 Cooling Fan failed and this procedure was exactly what I needed to install a new fan. The steps are right on. I would have done a lot of experimentation and possible damage had I not had this reference to follow. Thank you very much.
