Antwoord op "Will not turn on - battery or charging circuit?"Hi, my fire 8 wouldn’t charge and the screen seemed ‘stuck’ swiping didn’t work. I couldn’t even turn the dang thing off! I went online to the Amazon site and was going to contact them and they said to first try turning it off then back on. Here comes the ‘kicker’, they said to hold the power button down for 40 seconds, the screen would go black and then wait a second to turn it back on. IT WORKED!!! OMG! I guess I waited too long to do software updates. I normally just close the cover instead of powering it off. Maybe it will work for you?
