Charging your Kindle would not have anything to do with you closing your Amazon account.
Please plug in your Kindle for 5 minutes then hold down the power button for 45 seconds while it is plugged in until the Kindle reboots. It can take 2-3 minutes for the complete reboot process. Allow 30 minutes for a chargeIf that does not work then please let me know when you purchased the Kindle
The method that I have provided is slightly different from the basic reboot that you do while holding down the buttons.
