My kindle 8th gen suffered a heavy impact drop. The screen was not damaged and for a few days would show the entirety of the home screen when I plugged it in to charge but it would not hold any battery. Soon it stopped recognizing that it was plugged in at all (no light). Now I want to self-repair but am not sure if it’s the battery or the socket that needs replacing. Have taken apart components and nothing appears broken or disconnected.. Any help greatly appreciated, want to understand how these things work. I wonder why there is no troubleshoot for kindle 8th? Is it not so different from the 7th?
Update: post alcohol clean, we now have a flickering green light!
If it isn’t recognizing that it is plugged in at all it is likely the charge port/socket. If you’ve tried multiple cables I’d start with the charge port and go from there. Does it fee loose when you plug in it? Some charge ports on the kindle do require soldering though. Let us know how it goes!
