I have a 2011 Macbook pro that got wet and won’t start up now. I have installed ram and hard drive in a mac mini and in PCs before but I have never opened up a Macbook before. How hard is it to change the logic board?
It’s pretty difficult but definitely possible. Click here for a guide on how to do it.
You need to disassemble the whole device and put the boards in alcohol. this is basically emptying out the device: MacBook Pro 13" Unibody Late 2011 Upper Case Replacement how to fix the damage: Electronics Water Damage
