I have a Samsung note 10.1 that would not power on. I replaced the battery and it worked until battery drained. It will not charge. There is no battery icon on the screen and even though the charger( brand new Samsung) is plugged in it still says plug in the charger. I know the charger cube works because I’ve tested it on my new Samsung tablet but cannot check 30 pin cord as i do not have any device it will fit. My guess is either get new 30 pin cord or replace the charge port? I cannot find anything online about a missing battery icon. Anyone else having this issue? Any suggestions? Thanks
