Should I change the logic board myself?
My MacBook Air (Mid-2013: 256GB 1.3 GHz 4GB) stopped working since August 14, 2017. At first I thought it was just a drained battery, I charged it, but something seems wrong.
Sometimes the LED on the MagSafe connector would light up but eventually turn off that it isn't charging anymore. I brought it to an authorized Apple service center on the mid of September. The repair guy told me they found corrosion on the main logic board of my system, specifically near the airport card. They also told me that the only remedy to this problem is to change the main logic board which costs about the same as buying a new MacBook Air. I didn't ask any further, I told them I wanted my system back and walked away from the service center.
I ordered the screwdriver from iFixit so that I could check the inside of my system myself to see if there is really corrosion on the logic board. I didn't find any corrosion as what they said they saw. But, what I noticed was more surprising. I saw condensation on the logic board of my MacBook Air.
So I swabbed the surface of the logic board with a Q-Tip with alcohol and let it go dry.
After this I tried to charge my system and surprisingly it booted up but then it went off after having gone to the desktop. I tried recharging my system but this time it wasn't charging anymore. It only shows the amber light on the magsafe connector until eventually the magsafe light would not come on.
Can someone help me? I don't know if I would change the logic board of my system or just the I/O board or what.
Questa è una buona domanda?
