Dell Inspiron 16 2-in-1 7640 Intel Core Ultra 7 155U Stylus Not Working Fix Windows 11

The stylus pen on your Dell Inspiron 16 2-in-1 7640 Intel Core Ultra 7 155U is not working – no cursor appears when hovering the pen near the screen, pen input is not recognized in drawing applications, or the pen buttons produce no function. Pen digitizer driver updates restore stylus functionality on the Dell Inspiron 16 2-in-1 7640.

This guide covers pen driver updates, stylus battery check, and Windows Ink configuration for the Dell Inspiron 16 2-in-1 7640 Intel Core Ultra 7 155U in Windows 11.

“Inspiron 16 2-in-1 7640 stylus stopped responding after Windows update. Dell SupportAssist had Goodix pen digitizer driver update. After installing, pen hover distance increased and pressure sensitivity returned. Driver update was the only fix needed.” – Ilyani, graphic design student from Cyberjaya

Why Stylus Does Not Work on Dell Inspiron 16 2-in-1 7640

The Dell Inspiron 16 2-in-1 7640 uses a Goodix MPP (Microsoft Pen Protocol) pen digitizer embedded beneath the touchscreen glass. The Goodix digitizer requires a specific driver for Windows to process pen electromagnetic field detection, pressure levels (4096 levels), tilt data, and button state. After Windows Update, the Goodix MPP driver can be replaced with a generic HID pen driver that provides only basic position tracking without pressure sensitivity, tilt, hover detection, or eraser functionality. Without the correct Goodix MPP driver, the pen may appear completely non-functional if the generic driver fails to initialize the MPP detection frequency correctly.

• Goodix MPP pen driver replaced by generic HID driver after Windows Update
• Stylus battery depleted – pen produces no MPP electromagnetic signal
• Windows Ink disabled in Settings – Bluetooth and devices – Pen settings
• Pen digitizer disabled in Device Manager under Human Interface Devices

Fix 1 – Update Pen Driver via Dell SupportAssist

Open Dell SupportAssist and run System Update. Install Goodix Stylus Driver, Wacom Pen Driver, or Dell Stylus driver updates. Restart. After restart, hold the pen tip within 1cm of the display surface without touching – a cursor should appear at the pen tip position if hover detection is working. Test pressure by drawing in MS Paint or OneNote – varying pen pressure should produce different line widths. The Dell SupportAssist pen driver for the Inspiron 16 2-in-1 7640 Intel Core Ultra 7 155U includes the correct Goodix MPP firmware file and pen detection parameters tuned for the specific panel and digitizer configuration in the Inspiron 16 7640 chassis design.

Fix 2 – Check Stylus Battery

The Dell Active Pen and compatible MPP 2.0 styluses use a AAAA battery or rechargeable cell. If the pen LED indicator does not light when the button is pressed, the battery may be depleted. Replace the AAAA battery (remove top cap, pull out old battery, insert new one with correct polarity) or charge via the USB charging method if the pen supports it. A depleted stylus battery produces no MPP electromagnetic field that the Goodix digitizer can detect – the pen appears completely non-functional regardless of driver state. After replacing or charging, bring pen near display and verify hover cursor appears. Most Dell Active Pen batteries last 6-12 months with regular use before replacement is needed.

Check Device Manager for Pen Device

Open Device Manager – Human Interface Devices. When holding the pen near the screen, look for a Goodix Pen Device, HID-compliant pen, or Wacom Tablet entry that appears and disappears as you move the pen in and out of hover range. A functioning pen digitizer shows a pen device entry in HID when the pen is close to the screen. If no device appears, the digitizer is not detecting the pen MPP signal – check pen battery first. If a device appears with a yellow warning icon, right-click – Update driver. If Device Manager shows the pen device without error but pen input still does not work in applications, verify the applications have stylus input support enabled or test in Windows Ink Workspace on the Dell Inspiron 16 2-in-1 7640.

Fix 3 – Configure Windows Ink Settings

Go to Settings – Bluetooth and devices – Pen and Windows Ink. Verify pen settings are enabled. In the Pen and Windows Ink settings, find the pen input options and ensure Write with your fingertip is enabled or disabled based on preference – if enabled, finger touch can register as pen input which may confuse apps expecting stylus-only input. Also check the Shortcut button (pen button) mapping settings are configured for the desired actions. After driver update, Windows Ink pen settings sometimes reset to defaults – reconfigure pen button assignments (click, double-click, erase) to restore the previous workflow for drawing and note-taking applications on the Dell Inspiron 16 2-in-1 7640 Intel Core Ultra 7 155U digitizer system.

Fix 4 – Test in Different Applications

Test the stylus in multiple applications to determine if the issue is application-specific or system-wide. Windows Ink Workspace (click the pen icon in taskbar) – Sticky Notes and Whiteboard confirm system-level pen input. Microsoft OneNote and MS Paint support pressure sensitivity. If pen works in Windows Ink Workspace apps but not in a specific third-party application, the issue is the application’s pen input configuration rather than the driver or hardware. In applications like Adobe Photoshop or Clip Studio Paint, verify the stylus input device is configured in the application preferences under Stylus Input or Tablet settings, and the Goodix digitizer is listed as the active pen input source for the Dell Inspiron 16 2-in-1 7640.

Frequently Asked Questions

How do I fix stylus not working on Dell Inspiron 16 2-in-1 7640 Intel Core Ultra 7 155U?

Update Goodix MPP pen driver via Dell SupportAssist. Check stylus AAAA battery charge. Verify pen in Device Manager – Human Interface Devices. Test hover detection 1cm from screen.

What pen works with Dell Inspiron 16 2-in-1 7640 Intel Core Ultra 7 155U?

MPP 2.0 compatible pens: Dell Active Pen (recommended), Microsoft Surface Pen, HP Active Pen G3. Must be MPP protocol – non-MPP styluses do not work with the Goodix digitizer.

Does Dell Inspiron 16 2-in-1 7640 support tilt input from stylus?

Yes – tilt and rotation with MPP 2.0 tilt-capable styluses. Requires current Goodix MPP driver from Dell SupportAssist for tilt data processing in Windows Ink compatible applications.

Why does Dell Inspiron 16 2-in-1 stylus hover not work?

Goodix MPP driver missing or pen battery depleted. Driver update from Dell SupportAssist and new AAAA battery are the two most common fixes for no hover detection on the Inspiron 16 2-in-1 7640.

Conclusion

Dell Inspiron 16 2-in-1 7640 Intel Core Ultra 7 155U stylus not working in Windows 11 is resolved by Goodix MPP pen driver update via Dell SupportAssist restoring pressure sensitivity, tilt detection, hover range, and pen button functionality. Stylus AAAA battery replacement eliminates the most common hardware cause of complete pen non-detection. Device Manager HID pen device appearance test distinguishes driver issues from battery or signal problems. Windows Ink settings configuration after driver update restores pen button mapping for efficient note-taking and drawing workflows on the Dell Inspiron 16 2-in-1 7640 touchscreen display.
