Thank you for your respond. I tried all those suggestions. Today is my second time. The first was due to McAfee app installing for no reason. Killed the installation and uninstalled my McAfee. Restart didn't work. So I shut it down and left the connector flashes amber alone. Came back later it was fully charged.
This morning same situation happened at around 47% with connector flashes amber repeatedly. No lightening charging symbol. Still the same when I came home in the evening. Restart didn't work. Shutdown and when to the gym. 1 hour later the connector turned solid amber with the lightning symbol across an empty battery symbol. When I click on the empty battery symbol, it got refreshed with 98% charged. The solid amber just turned green on the connector, now with a 100% battery and lightening symbol. I still feel something is wrong. All battery stats indicates that battery is ok.
