Can I upgrade logic board on mid 2009
I have MacBook Air 13" mid 2009 with El Capitan installed. EC requires 4GB of RAM and I only have 2 which of course causes many problems.
RAM is soldered in so I was wondering if I could replace the logic board with one having 4, 6 or 8 GB of RAM? Is this difficult or even possible?
Currently it has 1.86 intel core 2 Duo and 2GB 1067 MHz DDR3 RAM.
Is this a good question?
