• 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.
• If you have installed a screen protector, it may be preventing the touchscreen from registering that you are touching the screen (this may occur if it is not designed for a capacitive touchscreen or has bubbles in it).Shut down and restart the computer. Attach a mouse to the computer.
• Get to your computer's product page, and to the Advanced tab. Choose a Diagnostic Test tab.Scroll down until Touchscreen appears and highlight it.
