I have a doubt over a 820 00165 Macbook air.
Does this machine turn on without battery or not when having the charger connected.
Is the first time I work on a 2015 Macbook air and never thinked to connect the battery while troubleshooting after 4 hours of misery :( and replacing the corroded parts I reassemble the machine and once I connect the charger it turns on.
Is this normal or I'm missing something?
