  1. Awesome!!

  2. Thank you very much! I found my HP Envy very difficult and scary to open but your tutorial made it very easy. I will donate but dont have any money right now. I promise though that as soon as I get I will. I love people that are ready to help others progress and this site seems dedicated to that. Thank you again very much!

    My fan stopped working and started making ver loud noises this morning. After many minutes of searching i stumbled upon your site with some skepticism because i prefer video tutorials to just pictures but like I said it was very easy to follow. It took me about 4 hours to complete opening and closing but it was very very easy. Thank you once again.

    This helped me out a ton. Thank you very much.

  4. Is it really necessary to disassemble the whole thing to get the fan out?

  5. IML Tech

    @ Tami,
    Yes it is. The fan is mounted under the motherboard and there is no easy way around.

  6. Thank you for this. It’s rare to see this detailed of steps for disassembling a laptop. I didn’t need it, but you should also cover opening the screen casing. Thanks again!

    Great tutorial! I had an extra piece though. It’s a small rubber piece (about 1/2 X 1/4″). I think it’s some kind of spacer. It has a couple tips on top? Hard to describe. I think it may have been taped to the top of the thermal fan on the side? I think it came off and fell in the fan and created my fan problem. We’ll see once I reassemble.
