It has happened to both our Fires and it definitely and internal power issue. All I did was call Kindle Support, explain the problem and they are sending us a replacement. There is no better customer service than Kindle's!!! Here's their number if you are having any problems: 866.216.1072, before calling you may want to try troubleshooting so you can say that you already did this: try a different charger (that didn't fix our problem), and then reboot (that didn't fix our problem). Called and explained the problem, we had already done the trouble shooting, so they are sending a replacement in 2 days.
I had the same issue and freaked out. It was fully charged. I just put it aside for a few minutes and when I picked it up again it would not turn on. After several attempts to hold down the power button I gave up trying thinking it was bricked and that I would need to get a replacement. My friend then picked it up and tapped the power button just once and it turned on instantly. Its been working perfectly since.
Thanx this solution made my kindle alive.. :-)
So it's nice this is a rare event... Since I posted the problem, it's happened a second time to me - but the same workaround fixed it.
Thanks for posting this, I've only had it happen once. But another friend also had it happen with theirs within a few days of purchase.
This is NOT a 'rare event' - even the amazon blogs are full of an increasing number of charging complaints. Apparently there is a bad micro usb socket behind the mess. I had the issue early on and contacted TS and got the hard reset solution mentioned here. That only postponed the problem until the unit was out of warranty.
It is sad that such a dandy little system can be rendenered useless by a minor failure point. I am pre-ordering my Google Nexus. Hopefully their same-priced product is more reliable.
This has happened to me several times. First time I freaked out, now it just pisses me off
Thank you so much for this help! I took it to Best Buy where it was bought, and the guy said he needed to look at the charger itself. I had tried other chargers, but to no avail. I tried your remedy, and it worked! Now my daughter can use her Kindle once more. If this problem persists too many times more, I will be contacting Kindle suppport myself. Once again, thank you!
