Does someone know if there are any pens (manufactured by Dell or another company) [examples: HP or Wacom] that are compatible with the Latitude 5290 2-in-1 that do not use coin-cell batteries? Is pen PN557W the only pen that is compatible with the Latitude 5290 2-in-1? I was working with my pen to try to resolve its top button not working. But, in doing so, I now have the circuit board set on my table, not in the pen and the coin-cell batteries in a storage bag. The AAAA-size battery and nib are unaffected.
