I have the infamous "battery not charging" problem on my 2014 Retina MacBook Pro. The power source shows as "Power source: power adapter".
I checked system info and I have 1100+ cycles, which I guess is a lot. So my guess is that the battery is dead, and so it stopped charging.
Right now, the battery percentage shows 6% and seems to be staying that way. It is not increasing at all.
What worries me is every time I reboot, the battery seems to drain a bit, meaning that after sufficient reboots the battery will eventually reach 0% (as my MacBook isn't charging), and at that point I won't be able to boot up again at all.
Should I set all my energy settings to "never sleep", "never turn off", etc. to prevent any rebooting, so that the battery does not drain any further?
What can I do short of buying a new computer? I don't think there is Apple service where I am for the next few weeks. I would buy a new charger, but it appears that the charger is not the problem (or at least there is a good chance it isn't).
Coconut Battery status: 8440 mAh, Full charge capacity 6973 mAh (guess that means my battery is 82% healthy?), Cycle count: 1177, macOS battery status: good.
