Touchscreen not responding or accurate on Mesa 2
4 Apr 2016
Turning the Mesa 2 sideways so the screen auto-rotates (as it does by default) may force the touch profile to refresh and hopefully resolve the issue.
System device drivers may not be loaded correctly, including those related to the touchscreen. Please refer to the following support article.
The touchscreen may not respond in cold wet conditions unless you apply the suggestions in the following article.
Installing firmware BIOS (UEFI) version 22 or higher resolves a fairly uncommon potential cause to issues with the touchscreen.
Performing a Hard Reset may get the touchscreen hardware to be visible and operational again. This is done by holding the Power button for more than 17 seconds until even the red LED stops flashing (this will disconnect all power and drain the system), waiting a few seconds (for the system to complete draining, particularly the touch controller), then connect wall charger, wait a few more seconds (for power circuitry to re-connect), briefly press the Power button again, and then wait for the system to load. You may need to press the Power button again if pressed too soon.
Removing an installed screen protector sheet may help, particularly in wet and/or cold conditions.
If the touchscreen responds normally while at the blue screen which appears after holding the bottom-left hardware Windows logo (Start) button while briefly pressing the bottom-right hardware Power button, then the issue may be software related. Software related issues can be identified and resolved using Task Manager and other tools exactly similar to as you would on a desktop computer. Some suggestions are at the following web page.
Reloading the touch profile or a different touch profile may help. Follow these steps if unable to use the touchscreen.
- Use the bottom hardware keys (or if needed attach a USB keyboard or mouse) to navigate to the Start menu or screen, and then scroll down to select the "Touchscreen Profiles" utility tile icon.
- While in the "Touchscreen Profiles" utility, select one of the non-highlighted touch profiles to switch to and load that profile.
- Wait for the loading progress bar to complete.
- Test the capacitive touchscreen for accuracy using the selected input or condition (profile) you selected.
If the capacitive touchscreen is now responding accurately, if desired you can switch back to the previous touch profile.
As noted in the user guide (manual) for the Mesa 2, the calibration tool in Microsoft Windows 10 may not work with the touchscreen on the Mesa 2. If this calibration tool is used, it may degrade touchscreen performance until a profile is loaded again as explained above.
Using a connected USB mouse, you can right-click on the bottom-left Start menu to select Device Manager > Human Interface Devices, right-click on "HID-compliant touch screen", select Disable, wait several second, and then repeat to Enable. You could possible also try Uninstall, but it can be difficult to re-install.
If the touchscreen stopped working after a Windows Update, under Start > Settings > Update & Security > Recovery there is an option to “Go back to the previous version of Windows 10” or “Go back to an earlier build” which may help. But that option is only available for a limited time after updating. If it works, you can do the Windows Update again, which should have more success in subsequent attempts.
If you are not able to get the touchscreen working, please contact firstname.lastname@example.org for further ideas. If the unit has encountered an impact or drop, the enhancements described at the following web page may help prevent such an issue in the future.
