Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble. It looks like Aric has opted out of the question and is no longer involved.
To your point - no, this is not a "scam", it is a legitimate support service, helping thousands of people daily with questions just like yours. It is intended to be an ongoing conversation though, not necessarily an instant fix.
You may see a call offer, but it is just that, an optional offer and is not required, we can certainly continue here in the chat format.
Since the initial steps did not help, it would tend to indicate that there is an internal hardware problem with the kindle (bad battery, faulty charging circuit, bad control board, etc).
There are many variables here, and ultimately not all issues can have a definitive "fix", though I'll go through all the possibilities with you to diagnose the problem and proceed as appropriate.
If the kindle still isn’t working properly, the next step will be a deeper level reset. If you have not charged the kindle recently or know that it is at least half full, then you should charge the battery for at least a few hours before proceeding further. Then plug the kindle into computer via usb cable, then press and hold power button for 60+ seconds, and release. The kindle will take 3-5 minutes to reload it's internal firmware. If it doesn't turn back on by itself, press power once to turn it on.
Let me know the results, and I'll advise further if needed.
