My PadFone mini 4.3's station has issues charging. Basically the station will act normally, then it will not show a light for charging for a couple of days but still accept a charge. During this time period it will allow me to plug the phone in/use the station but it will not charge the phone (with it in the station) if plugged in to the power cord. Also no sound in this configuration. Eventually it will not charge at all and will run the station out of power. After about a week or two it usually starts working again and then repeats. I can unplug the battery in the station and it will also start the process again. No issues with the phone and it charges normally on its own. Have tried hard, soft and factory resets with no no change. Sent it to Asus but they took 4 months and wanted $150 just for parts plus additional for $ the labor, however they couldn't tell me what was wrong or what parts they even needed. Any suggestions or guidance would be greatly appreciated.
