Troubleshooting Kindle 4 NT restarting by itself

Kszyniu · 02-05-2023, 06:32 AM

Hi, I'm having a problem with my Kindle 4 NT D01100. It was laying unused for a few years, however it was not damaged. I tried to run it again, but there is the problem. It charges and runs normally, however it freezes and then restarts by itself every 5 to 10 minutes. Here is a list of other sympthoms:
- It can't find any WiFi network; shows (0) WiFI networks available - same with 2.4 and 5GHz ones.
- Every time an action is performed (like turning a page or opening menu), it makes a silent buzzing sound, similiar to those made by HDD drives if you know what I mean. Every time it freezes before a restart the buzzing sound stops.
- The battery holds only about 1 day
And also a list of what I've already done:
-Factory reset
-Uncharging the battery to 0% and charging it to a 100%
-Disassembling it to check the internals, although everything seems fine there.
- Unregistering it and registering back, however I can't register it back as WiFI doesn't work
At this point I have tried probably everything I could find on the internet, however nothing worked. The software version is 4.14 so I think is up to date.
I've been thinking about replacing the battery, however those are kinda expensive where I live and I'm not sure if it would fix the problem.
I hope to find some help here, although I am aware that my Kindle can be simply dead. Thanks in advance for any advice.

worn out LiPoly cell (aka "battery"). Time and heat wears them out as well as charge cycles.
