Hi!
I bought a Paperwhite 1st Gen (Model EY21) off a marketplace where the guy claimed it doesn't turn on anymore and probably just needs a new battery. Turns out the battery is actually fine but the PW is stuck in a boot loop! I'm not mad because I only paid the equivalent of 10$...
When I first got it and pressed the power button the Kindle showed this huge battery symbol. So I connected it to my PC and it looked like it charged because the LED was orange and I actually could hear the typical Windows sound when you connect a USB device.
So next I hooked it to a lab power supply to see if it charges sufficiently. It did at the specified rate of almost 500mA (460 exactly). After half an hour the battery symbol went away (just a plain white screen) and the PW continued to charge at a 500mA rate. But at that point a funny thing started to happen. The Kindle would interrupt the charging every minute and reboot. So the Kindle charges at about 500mA for a minute, then drop to 100mA for 5 seconds, then 500mA again in an infinite loop. From the outside you can see that each time when it's at the beginning of the 100mA phase the screen flickers rapidly from white to black twice. W/B/W/B/W within a second.
Also now when I connect it to the PC I don't hear any sound or beep anymore. I have searched the forums but never came across a behaviour like this. Most boot loops I have read about were much longer where you could actually see the picture with the kid under the tree. Mine doesn't show any picture, except the huge battery symbol in the very beginning when the battery was too drained for the Kindle to boot.
In the meantime the battery seems to be fully charged because after the 5 seconds of booting the LED actually turns from orange to green for a minute before the boot loop strikes again. I have tried pressing the Home button for extended times (30s, 2min) but nothing interesting happens, it just continues to be stuck in this boot loop.
My next plan is to hook it up to a wall charger for week, but I don't have a lot of hope because I can see from the flickering of the screen and the LED that it's not repairing a file system or doing anything but just rebooting in the same pattern.
Does anyone know what's going on or have a better plan?:chinscratch:
