The stylus on the HP Dragonfly Pro shows no input when touching the screen. The AMD Ryzen 7 7736U model uses an ELAN touch and pen controller. Windows 11 updates can remove or replace the stylus driver, leaving touch working but pen input undetected.
Check Pen Battery and Re-Pair Check first
Replace the AAAA battery in the HP Tilt Pen or charge the USB-C pen if applicable. A low battery is the most common reason a stylus fails to detect on any MPP-compatible touchscreen. Press the pen tip on the screen — if nothing appears, proceed to driver fixes.
Run HP Support Assistant Updates
Open HP Support Assistant → Updates. Install all available driver updates. The ELAN touch and pen driver update from HP Support Assistant is the most common fix for stylus detection failures on the Dragonfly Pro after a Windows 11 update.
Reinstall ELAN Touch and Pen Driver
Device Manager → Human Interface Devices → find ELAN HID Stylus or ELAN WBF Fingerprint entries. Uninstall the touch driver. Download and install the ELAN driver from HP Support for Dragonfly Pro using your serial number. Restart and test the pen.
Check Pen and Windows Ink Settings
Settings → Bluetooth and devices → Pen and Windows Ink. Ensure Windows Ink workspace is enabled. Some pen input features require Windows Ink to be active. Toggle it off and on, then retest stylus input on the HP Dragonfly Pro screen.
“Running HP Support Assistant and installing the ELAN driver update brought the stylus back on my Dragonfly Pro — the Windows 11 update had removed it silently.” — Suraya, Bangsar
