Hi iFixit members, I have been given a Macbook Air 13" A1466 EMC2632 by a friend. Lucky me I hear you all saying LOL.. Well it’s not as simple as that. It has unfortuntely had a Tea spillage so I need to do some thorough testing and possible parts replacement…BUT I have done a full Board clean up, with IPA and light air blower, and physically cannot see any corrosion or nasty component damage. My friend advised me that it is a 2015 model with the extras added (that I can see on the OEM sticker but I need to ensure that the Schematic I am I following is correct to the physical laptop. Board identification is as follows: 820-3437-B MLB 1.7G HY 8G SI (not sure what the HY and SI mean though) Also could really do with some guidance in regards to the multimeter testing, such as what Parts essentially need to being connected up so that I get proper accurate readings…..and also Diode Mode or Resistance mode or Both preferred for testing the circuit. And lastly, what I should look out for in regards to drink spillage etc.. but I cannot see any components which look like they are fried or corroded. I have read a forum on here that mentions the 2015 model requires the battery connected to complete tests, but I am unsure if this is a 2015 model or earlier model. Your help would be very kindly apprecited thank you Paul
Given the systems age you likely need a new battery MacBook Air 13" (Late 2010-2017) Battery to really do any serious testing or even get it to run. A tea spill into the keyboard likely damaged the keyboard and/or trackpad so consider these costs as well. If you get it going what is your plan of usage? Also consider the highest Apple supported OS is OS-X Mavericks (10.9.5). You’ll need to locate a set of schematics and boardview drawings to work off of. Diagnosing a logic board will take a bit of work I would recommend you jump over to Louis Rossmann: The most Common Macbook Air logic board failure - how to fix
