My partners Macbook Air had an unfortunate encounter with some tea and couldn't be repaired under Apple Care. I just wrote some words about my experience at the site where I bought the magic screwdriver required to open it up, and where the instructions to do the job of replacing the broken logic board can be found. http://www.ifixit.com/Story/629/Replaced_a_Macbook_Air_logic_board If you're not already aware of ifixit.com I recommend checking it out, they have guides to repair just about everything and the parts and tools to help you do it. dave--- Manage your account options at //www.freelists.org/list/muglo
