We have a 500 series board where the teacher pens (2) and student pens (2) continue to stop working. We are on our 4th pen of the year. The driver is up to date. Have others run into something similar?
If the pens in question are able to operate other boards of the same model, then we would need to look at the board’s hardware as a possible cause of this behavior, and direct our troubleshooting accordingly.
If those pens are unable to work with any compatible board, then we would attempt to verify their warranty coverage using the serial number of the board with which they were included or a copy of the invoice under which they were purchased (if they were purchased separately from the board)
