Kindle Fire HDX 8.9" - battery indicator showed power was low, waited too long to plug in the charger, now it will not power up. Tried different chargers, overnight charging, and cables, even a PC overnight. Tried holding power button to reset as well as power and volume up. USB / charging port seems snug. My questions: If the battery was dead, would it turn on with the charger attached?Is there any type of circuit between the USB port and the battery that would require power from the battery in order to operate (to charge the battery)?Can I get access to the battery connections to manually put a small charge on the battery? (yes, I am willing to kludge together two ‘C’ cells and hook it to the internal battery to jump start the charging circuit if it exists.)Are the batteries the same for the HD and HDX?What did I not ask? Thank you for the teardown information!
Hi Nelson Answers to your questions: 1 yes it should turn on when plugged in 2 there is a circuit between the plug and battery, but it doesn’t need the battery to be charged to work. 3 you can get to the internal battery, but it will be more than a kludge http://ifixit.org/blog/5564/kindle-fire-… 4 I’m not sure, probably not. What might have happened is that your battery has failed. It won’t take a charge but is also ‘shorting’ the circuit meaning that the rest of the device isn’t getting any power. Maybe a battery replacement will fix it, but it’s hard to know. Good luck Ian
I just replaced my battery for my hdx 8.9 3rd gen and still won’t turn on.
