ASUS ExpertBook B7 Flip B7402: Pen Not Recognized
Intel Core i7-1195G7 • Windows 11 • 2-in-1 Business Laptop
The ASUS ExpertBook B7 Flip B7402 is a ruggedized 2-in-1 business laptop with a touchscreen and stylus support. The built-in pen digitizer supports the ASUS Pen (MPP 2.0) for note-taking and annotation. When the pen stops being recognized, the cause is usually a digitizer driver issue, a Windows Ink configuration problem, or a low-battery pen.
Check Pen Battery
The ASUS Pen MPP 2.0 uses a AAAA or AAA battery depending on the model. If the battery is depleted, the pen will not interact with the screen at all. Replace the battery and test immediately before proceeding with software fixes.
Restart HID Touch Services
Open Services.msc and restart Human Interface Device Service. Also check that Tablet PC Input Service is running and set to Automatic. These services manage stylus input routing in Windows 11.
Reinstall Pen Digitizer Driver
In Device Manager > Human Interface Devices, uninstall ELAN WBF Fingerprint Sensor and the HID-compliant pen entry. Download the updated digitizer driver from ASUS Support for the B7402.
Enable Windows Ink Workspace
Go to Settings > Bluetooth & devices > Pen & Windows Ink and ensure pen features are enabled. Also verify that Handwriting panel is not set to a mode that conflicts with the B7402 digitizer behavior.
Update BIOS
ASUS releases BIOS updates for the B7402 that fix pen input initialization in different hinge modes (laptop, tent, tablet). Update via MyASUS or ASUS Support to apply pen-related firmware patches.
Calibrate Pen Input
Search for Calibrate the screen for pen or touch input in Start. Run the pen calibration to re-align screen coordinates with pen tracking. After BIOS updates or screen replacements, calibration data may be misaligned.
“The pen on my ExpertBook B7 Flip stopped working completely. The AAAA battery inside had died — a new battery from a stationery shop fixed it in 2 minutes.”

The B7402 is compatible with the ASUS Pen MPP 2.0 and other Microsoft Pen Protocol 2.0 styluses. It supports 4,096 pressure levels and tilt recognition. Generic Wacom EMR pens are not compatible as the B7402 uses the MPP protocol.
Does the ASUS ExpertBook B7 Flip B7402 support palm rejection with the pen?
Yes. The B7402 touch digitizer supports palm rejection when using a compatible MPP 2.0 stylus. Ensure the ASUS pen driver is installed from ASUS Support for the best palm rejection behavior.
Can I use the B7402 pen in all hinge positions?
Yes. The pen digitizer functions in laptop, tent, and tablet modes. If pen input stops in a specific mode, the hinge sensor driver may need updating. Check ASUS Support for the latest MyASUS and hinge sensor driver for the B7402.
