When your touchscreen is not working correctly on your notebook or tablet in Windows 7, 8(8.1) and 10, follow the steps to help resolve the issues you are experiencing.
Please attempt the following steps:
Clean the LCD screen.
Turn off the computer closely examine the condition of the screen.
Take notice of any smudges or areas to be cleaned.
Use a microfiber cloth to remove any obvious dust and gently brush off any dirt particles.
Proper cleaning kits should be used to clean and keep your LCD displays in a crisp clear pristine condition.
Never spray any cleaning solutions directly on to the screen; spray it into the cleaning cloth.
Very gently wipe the screen in a circular motion. Do not press hard on the cloth.
Do not leave any liquid on the screen. Remove all excess moisture as it may damage your screen.
For stains that are hard to remove, repeat this procedure as needed.
Let the LCD screen dry thoroughly before you turn it back on.
When you have installed a screen protector, it may be preventing the touchscreen from registering that you are touching the screen and may need to be removed (this may occur if it is not designed for a capacitive touchscreen or has bubbles in it).
Shut down and restart the computer or tablet.
NOTE: When the touchscreen starts responding again, no further actions are needed.
Calibrate the touchscreen.
Click on the tab that matches the Operating System (OS) installed on your computer and perform the steps within that section to calibrate the touchscreen.
