replacing battery and airport card

Mi Problema

The airport card didn't work fine. After years of use the wireless connection was impossible and i could go in internet only with the ethernet cable. Also the battery, after years of use didn't keep the power, i could use the macbook only with the power cable connected.

Mi Solución

All fine! Very simple find the right component with my model.

I picked up the most recent compatible airport card and watching the manual was very easy to install it. All fine and now my macbook is as new!!!

Mi Consejo

The only advice is to store the screws not all togheter because they are all similar and is not easy to place them into the right place if not stored separately step by step
