HP Envy 15 Intel Core Ultra 7 155H Touchscreen Not Working Fix Windows 11

The touchscreen on your HP Envy 15 Intel Core Ultra 7 155H does not respond to finger touch – tapping the display produces no cursor movement or selection, or the touchscreen worked previously but stopped after a Windows 11 update. HID touchscreen driver updates and device enable settings restore touch functionality on the HP Envy 15.

This guide covers HID touchscreen driver installation, Device Manager troubleshooting, and Windows touch settings for the HP Envy 15 Intel Core Ultra 7 155H in Windows 11.

“HP Envy 15 touchscreen stopped after Windows update. Device Manager showed HID touchscreen with error code 10. HP Support Assistant had touchscreen driver update. After installing and restarting, touch worked perfectly again.” – Suhaila, nurse from Selayang

Why Touchscreen Does Not Work on HP Envy 15

The HP Envy 15 touchscreen uses an HID (Human Interface Device) touchscreen controller that requires specific driver for multi-touch gesture support and palm rejection. After Windows 11 updates, the HID touchscreen driver can be replaced by a generic Microsoft HID input driver that provides basic single-touch input but loses multi-touch gesture capabilities. In some cases the driver update fails entirely, leaving the touchscreen in an error state in Device Manager where it appears listed but with error code 10 (device cannot start) – at this point no touch input is registered.

• HID touchscreen driver replaced by generic driver after Windows Update – error code 10
• Touchscreen device disabled in Device Manager during Windows Update driver refresh
• Touchscreen driver conflict with recent Windows 11 feature update components
• Touch service disabled – Tablet PC Input Service stopped in services.msc

Fix 1 – Check and Enable Touchscreen in Device Manager

Open Device Manager and expand Human Interface Devices. Look for HID-compliant touchscreen. If it has a down arrow icon, it is disabled – right-click and select Enable device. If it has a yellow warning triangle, right-click and select Update driver – Search automatically. If no touchscreen device appears at all in Human Interface Devices, click Action – Scan for hardware changes. The touchscreen controller sometimes disappears from Device Manager after a failed driver update and requires a hardware scan to re-enumerate it before driver reinstallation can proceed on the HP Envy 15.

Fix 2 – Update HID Touchscreen Driver from HP Support

Open HP Support Assistant and check for HID touchscreen or Elan/Goodix/Synaptics touchscreen driver updates. Install and restart. HP Envy 15 Intel Core Ultra 7 155H touchscreen may use Elan, Goodix, or ILITEK touchscreen controller depending on manufacturing variant. The HP-qualified touchscreen driver is the correct version for the specific touchscreen controller in the HP Envy 15 display assembly. After driver installation, test by opening the Windows Touch Keyboard from taskbar and tapping on-screen keys to confirm multi-touch input is registering across the full display area.

Restart Tablet PC Input Service

Press Windows+R and type services.msc. Find Tablet PC Input Service. Set Startup type to Automatic and click Start if it is stopped. The Tablet PC Input Service provides the system-level touch input processing that converts raw HID touchscreen digitizer data into Windows touch events. If this service is stopped, touch input from the HID driver is not processed into Windows cursor events or gesture recognition, causing the touchscreen to appear completely non-functional even when the hardware and driver are working correctly on the HP Envy 15.

Fix 3 – Disable Touchscreen Power Saving

In Device Manager – Human Interface Devices – HID-compliant touchscreen – Properties – Power Management. Uncheck Allow the computer to turn off this device to save power. Touchscreen power saving on the HP Envy 15 can cause the touch controller to enter a low-power state during display sleep, and occasionally fail to fully reinitialize when the display wakes. The touchscreen appears to work after wake but registers no input because the controller is in a partial-wake state. Disabling power saving forces the touchscreen controller to remain fully initialized through sleep and wake cycles.

Fix 4 – Reset Touch Calibration

Search for Calibrate in Windows search – open Calibrate the screen for pen or touch input. Select Touch input. Click Reset to restore factory calibration data. If the touchscreen registers input but the touch point is visibly offset from where fingers actually touch the screen, calibration drift has occurred. Touch calibration drift on the HP Envy 15 can happen after display driver updates or after physical display pressure. Resetting calibration removes the offset and re-aligns touch input registration to the correct physical screen position, restoring accurate tap and gesture recognition across all display areas.

Conclusion

HP Envy 15 Intel Core Ultra 7 155H touchscreen not working in Windows 11 is resolved by enabling the HID-compliant touchscreen in Device Manager and updating the driver via HP Support Assistant. Tablet PC Input Service must be running in Automatic startup mode for touch events to be processed by Windows. Disabling touchscreen device power saving prevents incomplete wake-from-sleep states that cause intermittent non-response. Touch calibration reset corrects offset between physical touch location and screen cursor position after display driver updates.
