battery is draining while plugged-in
Batter started draining while plugged-in even when there was no significant use of any apps. It happened several days after i upgraded to Catalina 10.15.5. went apple service provider and they changed motherboard and power board but still having the same problem. Any suggestions ? I'm using MBA 2019, relatively new.Thanks!
Note: find attached the image. it says battery is charged but it keeps draining
