Hello, I have the same Problem the my device is shutting down even Battery charge showing 94 % but it will not stay for long, on when disconnected from power. Just tested again -- shut down at 89 %.
There is mentioned that this Issue can be solved by replacing the battery. I even got the problem of loose USB Port. Following questions, with I would appreciate any answer.
1.) Does somebody know, a model type of battery I could use, and where to order it?
2.) Does someone have some advice and hints how to open the Inkpad3 and not to breake anything?
3.) Is there maybe also an online ressource, to order parts like this built in USB Port.
already in advance for your replies.
Best regards
Matthias
