30 minutes - 2 hours
Well. As like everyone, once you hear a noise, you start to get frustrated. The Noise goes off and comes back on, and keeps bothering you. So next step, is either break your computer, or take it to someone to repair it. and let them charge you a fortune to fix a little problem. which maybe you can fix your self. if you tried.
The place to find a solution - ifixit.. hats off to you guys, seriously. i cant believe how easy it is to fix something.
It was so easy, this is my third time i have ordered fans. i got many laptops.. and all needed a fan replacement. As this was my third time buying, i even didn't need to open the guide to see. (but for sure i check it right after i put it all back together. just to double check i did it right). And i did.
I got to say. i am very excited. its something anybody can do. And as long as you follow the guidelines. not much can go wrong. and if it does. Im sure ifixit will be more than happy to help you.
Dont touch anything until you first see the guides. Thats what they are for. to show you whats underneath. Once your ready. just got for it. you will be very satisfied with the end result. happy fixing with ifixit. you guys rock. simple and efficient and effective.
