I am stuck with Active Pen 557W and Latitude 7490.
Have tried to download Active Pen drivers but just get a message "No tablet detected on the system"
I just want to use the pen!!!
Same issue for me, model pn556w. I read many posts about defective design of the case and tried to fix it as shown on the picture. I inserted M3 screw nut to the bottom of the AAAA case since it fitted well and its height allows to have a permanent contact to the '+' of AAAA battery. Also very important is to fix the nut so it doesn't move up thanks to a piece of black plastic preventing a short circuit! Be careful!
Works well so far.
Have you tried to switch the pen mode from AES to MPP?
• Press briefly on both Bottom Barrel Button and Top Barrel
Button, to indicate the current Inking Mode as follows:
• Microsoft Pen Protocol (MPP) — Blinks twice
• Wacom Active Electrostatic (AES) — Blinks once
• Press and hold for 2 seconds on both Bottom Barrel
Button and Top Barrel Button to trigger Mode Switching.
After completion of mode switching, indicator will show
the current effective Mode as follows:
• MPP — Blinks twice
• AES — Blinks once
