Hi, My name is***** will assist you. I am sorry to hear that you are having this issue.This is usually caused by a glitch in the firmware and can be resolved by a forced reboot, then your kindle will work normally again. Slide or press and hold the power switch for 40 second, then release. Then wait about 1 minute and power back on normally.Please let me know if this does not work for you,
did that work for you?
Please let me know if you need more help.
