I have strange charging behavior that started some time ago. My MBP16 (Catalina 10.15.5 (19F101)) just stopped charging until i do some actions.
[!]ITS HAPPENING RANDOMLY, not all the times.
AND EACH CONNECTION OF POWER ADAPTER MAKES 'CHARGING' SOUND. :)
So my flow:
- Going back from office -> home, connect the same charger, HEAR 'charging sound', wake up laptop. Sometimes it's charging, sometimes it's not (recently started having it).
- Going to office from home, the same flow, the same results.
Charging icon is exist except the case the battery is running out. Power settings says battery is ok (i bought it just some time ago), i'm using it with original power adapter. And only restart macbook (or SCM sometimes) is helping me. So it looks like after sleep mode it's not charged from time to time. It really looks like software bug but i'm not sure, because i can see it's not charging, i don't touch/move any cables/adapter, just restart it - and it's fine. The same ports, other ports, nevermind - just discharging with connected power AC until restart/reset. So i'b doubt about "Defective battery/Defective charger" point.
Any ideas please? :(
Diagnostic test says - ADP000 (no issue).
