I'm having an issue where my keyboard is not charging at all showing 0% or it will sometimes show 100%. The wireless mode will go in and out and keep disconnecting. When I plug it in it works fine, but sometimes Synapse shows the battery at 0% and not charging, or completely charged at 100%. This is a new problem and I’ve had the keyboard about a year. I have downloaded and updated firmware, synapse, and the pairing utility and none of this has fixed the issue.
