The touchscreen on your Dell Latitude 9450 Intel Core Ultra 7 164U 2-in-1 does not respond to finger touch – taps and swipes produce no cursor movement, the screen works as a normal display but not touch input, or touch input stopped working after a Windows update. Touch driver updates restore touchscreen functionality on the Dell Latitude 9450 2-in-1.
This guide covers touch driver updates, Device Manager enable, and touch input settings for the Dell Latitude 9450 Intel Core Ultra 7 164U 2-in-1 in Windows 11.
“Dell Latitude 9450 2-in-1 Core Ultra 7 164U touchscreen stopped responding after Windows update. Device Manager showed HID-compliant touch screen with error code 10. Dell SupportAssist installed touch driver update. After restart, touchscreen responded perfectly to all touch and swipe gestures.” – Rahayu, HR manager from Menara Maxis

Why Touchscreen Does Not Work on Dell Latitude 9450 2-in-1
The Dell Latitude 9450 2-in-1 touchscreen uses a digitizer controller (typically Goodix or ELAN) connected via USB or I2C interface. Windows Update can replace the Dell-validated touch driver with a generic HID (Human Interface Device) driver that does not correctly initialize the Latitude 9450 touch panel multitouch configuration, causing the touchscreen to appear as a detected device in Device Manager but not produce any touch input in Windows. Enterprise Dell Latitude configurations with MDM management can also have touch input disabled by group policy for security reasons in restricted computing environments.
- Touch driver replaced by generic HID driver after Windows Update
- Touch device disabled in Device Manager by accident or group policy
- Touch input turned off in Windows Settings – Bluetooth and devices – Touch
- Touch panel driver error code 10 or 45 requiring driver reinstall

Fix 1 – Update Touch Driver via Dell SupportAssist
Open Dell SupportAssist and run System Update. Look for Goodix Touchscreen Driver, ELAN Touch Driver, or HID Touchscreen Driver updates. Install and restart. After restart, touch the display to test finger input – a working touchscreen shows a ripple or cursor movement immediately on contact. Touch driver updates from Dell SupportAssist for the Latitude 9450 include the correct Dell OEM multitouch calibration profile for the 2-in-1 panel dimensions, ensuring 10-point multitouch, palm rejection in laptop mode, and stylus co-presence with finger input work correctly together on the Latitude 9450 2-in-1 hinge configuration.
Fix 2 – Enable Touch Device in Device Manager
Open Device Manager – Human Interface Devices. Look for HID-compliant touch screen entry. If it shows with a yellow warning icon or a down-arrow (disabled) icon: right-click – Enable device (if disabled). If it shows with error code 10 or 45: right-click – Uninstall device – restart. Windows reinstalls the driver. If the touch device does not appear in Device Manager at all, check under Device Manager – View – Show hidden devices, as the touch controller may be disabled at the hardware level by a device policy rather than visible as an active device node on the Dell Latitude 9450 2-in-1 Intel Core Ultra 7 164U enterprise platform.
Toggle Touch Input in Windows Settings
Go to Settings – Bluetooth and devices – Touch. Find the touch input toggle and ensure it is On. If it shows as On but touchscreen still does not work, toggle it Off, wait 5 seconds, then toggle back On. This forces Windows to reinitialize the touch input subsystem and re-establish connection with the Goodix or ELAN digitizer driver. On enterprise Dell Latitude configurations, IT administrators can use Group Policy to disable touch input system-wide – if the toggle is grayed out and cannot be changed, contact IT support to verify whether a group policy is blocking touch input on the Dell Latitude 9450 in the corporate device management environment.

Fix 3 – Restart HID Input Service
Press Windows+R and type services.msc. Find Human Interface Device Service. Right-click – Restart. This restarts the Windows HID service that manages all touch input processing including the Latitude 9450 touchscreen digitizer communication. After service restart, test touchscreen immediately. If HID service restart resolves touch but the issue returns after sleep or restart, set the HID service to Automatic startup to ensure it always starts and maintains touch input connectivity. A stopped or crashed HID service produces complete loss of touch input on 2-in-1 devices where touch is the primary input modality in tablet mode on the Dell Latitude 9450 Intel Core Ultra 7 164U platform.
Fix 4 – Rotate Screen Mode and Test
Convert the Dell Latitude 9450 to full tablet mode (rotate display 360 degrees). In tablet mode, touch input is the primary interaction method and Windows prioritizes touch digitizer initialization. If touch works in tablet mode but not in laptop mode, the hinge position sensor may be providing incorrect mode data to Windows, causing Windows to deprioritize touch input in what it believes is keyboard-open laptop mode. Test touch in each orientation (laptop, tent, stand, tablet) to identify if the issue is mode-specific or universal. A touch issue in all orientations indicates a driver problem, while orientation-specific issues indicate a hinge sensor or mode detection problem requiring Dell service on the Latitude 9450 2-in-1.
Frequently Asked Questions
How do I fix touchscreen not working on Dell Latitude 9450 Intel Core Ultra 7 164U 2-in-1?
Update touch driver via Dell SupportAssist. Enable HID touch screen in Device Manager. Toggle Touch in Settings – Bluetooth – Touch. Restart HID Input Service in services.msc. Test in all 2-in-1 orientations.
Why is Dell Latitude 9450 2-in-1 touchscreen not responding to touch?
Touch driver error after Windows Update (most common). Dell SupportAssist touch driver update resolves most cases. Device Manager enable for disabled touch device resolves enterprise group policy or accidental disable.
Does Dell Latitude 9450 Intel Core Ultra 7 164U have Windows Hello face recognition?
Yes – IR camera for Windows Hello face recognition. Setup: Settings – Accounts – Sign-in options – Facial recognition. Update Intel IPU6 camera driver via Dell SupportAssist for reliable face detection performance.
Why does Dell Latitude 9450 2-in-1 touchscreen work sometimes but not always?
Touch driver intermittent conflict. Device Manager – HID touch screen – disable and re-enable. Update touch driver via Dell SupportAssist. Disconnect USB peripherals that may interfere with HID device enumeration order.
Conclusion
Dell Latitude 9450 Intel Core Ultra 7 164U 2-in-1 touchscreen not working in Windows 11 is resolved by updating the Goodix or ELAN touch driver via Dell SupportAssist to restore correct OEM multitouch configuration after Windows Update generic driver replacement. Device Manager HID touch screen enable or reinstall fixes disabled or error-state touch device nodes. Windows Settings Touch toggle off-on reinitializes the touch input subsystem. HID Input Service restart restores touch communication without requiring full system restart. Orientation testing in all 2-in-1 modes distinguishes between universal driver issues and orientation-specific mode detection problems requiring Dell service on the Latitude 9450 enterprise 2-in-1 platform.
