Hi Manoe Singh,
Thank you for posting in Microsoft Community.
It appears that you are experiencing an issue with your Surface Pro6 device where the pen is functional, but the touch feature is not working. One possible explanation for this issue could be a touch driver problem.
Let’s work together in finding the best solution to this issue. Here are some steps you can try to resolve the issue:
- Boot to UEFI and test touch functionality: This will help determine if the issue is hardware or software related. (UEFI (Unified Extensible Firmware Interface) is an environment that exists completely outside of Windows and other installed applications.) If the issue exists in UEFI, then we know it's a hardware failure.
- To open UEFI screen, follow these steps:
- Go to Start > Power > Shut down.
- When Surface is off, press and hold the volume up button and press the power button until a Microsoft or Surface logo appears onscreen.
- Once you are in UEFI, touch your Surface screen and see if it responds normally. Try to navigate in UEFI by tapping various menu items. If touch doesn’t work on your Surface, your touchscreen most likely experienced a hardware failure. Your next step is to submit a service order. If touch works on your Surface, select EXIT, follow any onscreen instructions, and restart Windows. Then go to reinstall the touchscreen driver
- Reinstall the touchscreen driver: You can try reinstalling the touchscreen driver to see if that resolves the issue. To do this, follow these steps:
- In the search box on the taskbar, enter device manager, and then select Device Manager in the list of results.
- Expand the Human Interface Devices category.
- Right-click on the HID-compliant touch screen and select Uninstall device.
- Do not put any check mark on the small box that say complete delete just click uninstall below or okay.
- Right-click on Intel(R) Precise Touch Device and select Uninstall. same do not put any check mark on the box that say complete delete.
- Restart your Surface. Windows will automatically reinstall the driver.
- After all the steps and the device touch screen work in the UEFI and not in Windows environment. Next, we will need to Reset the Surface device back to default.
I hope I have answered all your questions. Please let me know how it goes.
Kind regards,
Christopher.
