Kindle 4 NT gets frozen in a sleep mode
Hello!
I have a Kindle 4 NT for more than a year and it was just perfect, but once I hadn't use it for a long time and when I got it there was a screen with a message to charge it. So I did. Then I turned it on and everything was fine until it went to a sleep mode with a screensaver. I pressed the 'ON' button but nothing happened. I followed the instruction on the amazon page: http://www.amazon.com/gp/help/custom...829000#restart. My Kindle rebooted and everything was OK until it went to sleep again. I pressed the 'ON' button but the Kindle didn't wake up. I also noticed that there was no green light at all, only yellow one when I charge the Kindle with the adapter or when I plug it into my computer. When I plug the Kindle into a computer it doesn't recognize the Kindle unless I hold the button for 20 seconds and it gets rebooted. Then it is recognized as a USB drive. I tried to reset the Kindle to the factory settings but it didn't change anything, the problem still remains. Then I reflashed the main and diagnostic partitions, it didn't help. Then I reflashed partitions and the main kernel, and it still gets frozen in a sleep mode. Everything else works as usual, I can read books, use Wi-Fi, and so on but if I don't use it for 10 minutes it goes to a sleep mode and gets frozen and I have to reboot it which takes a long time. Could you please advise me how I can fix this problem? Regards, Alexander |

Try doing a Factory Reset and see if that helps.
EDIT: Never mind, I see you've already tried that. No idea, in that case - sorry. What do Kindle Customer Service say? |

They sent me the instructions similar to http://www.amazon.com/gp/help/custom...829000#restart.
Unfortunately my warranty has expired. |

You can try to reflash the firmware with Kubrick LiveCD/LiveUSB.
That might help. |

Thanx for advice, I'll give it a try. I am already charging my Kindle.

I just used Kubrick, it didn't help.
I noticed that a reboot command freezes my Kindle and in order to continue rebooting I have to press the 'ON' button. Maybe it's hardware (or a battery)? |

My Kindle goes to a sleep mode in 10 minutes. Do you think it's possible to increase this time to 7 days or more?
