Regarding weird charging issues on Mac Air
My mac air A1466 suddenly stopped charging. 1stly I suspected magsafe failure issue as there was no LED light. But then I opened up the back pannel of the lappy and disconnected the battery. On plugging in the Adapter, the system turned on by the direct connection. While in that running state, I connected the battery. To my surprise it started getting charged up. But again when I unplugged the adapter and plugged it back, the battery wouldnt charge.(Note: I had done the SMC reset and all)
Q1) How can the laptop work on direct connection with adapter? Brief on the in buit connection of the charging port and the motherboard.
Q2)Is it safe to do ‘hot swap' of battery?
Q3) What can be the possible cause of my battery not charging? Whats at fault?
Q4) Can I use DMM to check for continuity between pins of the charging port ? Which pin pair should pass the test and which pair shouldnt.
Q5) Pls Suggest any other methods to check for faults within using the multimeter? Do elaborate.
