Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.
I can help you with this, but to be clear, this is a paid support service. The $5 was only a deposit to post your question, with the balance of the total fee being charged after speaking with an expert here. It is considered refundable if you don't get an answer, otherwise to continue you are agreeing to pay for my time and efforts in assisting you.
Initially, this symptom can indicate several possible issues: an internal hardware failure, a low/faulty battery, or just a simple memory/firmware glitch.
The first step here will be to attempt to reboot the kindle. This is done by pressing/sliding and holding the power button for 20+ seconds, or until the screen flashes (usually with an image of a tree), then release. Give the kindle about a minute to start back up, and let me know if the problem persists, we can then try some further steps.
