Right-click on “HID-compliant touch screen” and select “Update driver.” You’ll have two options: automatically search for updated drivers or manually browse for drivers on your computer. If you choose to search automatically, Windows will look for the latest driver online. If you have already downloaded a driver, you can select the manual option to install it.
How do I calibrate my touch screen?
Touch screen calibration ensures accurate touch input. Miscalibration can lead to inaccurate responses or a complete lack of responsiveness. Accessing the Tablet PC Settings in Windows allows you to recalibrate your touch screen.
You can find Tablet PC Settings by searching for “Calibrate the screen for pen or touch input” in the Windows search bar. Follow the on-screen instructions to tap the targets that appear on the screen. This process helps the system remap touch input to the correct locations, improving accuracy and responsiveness.
Will a system restore fix a non-responsive touch screen?
Performing a system restore can resolve touch screen issues, particularly if they arose after a recent software installation or system update. A system restore reverts your computer’s system files to a previous state, effectively undoing changes that may have caused the touch screen to stop working. This will not affect your personal documents.
However, a system restore might not be the solution if the problem stems from hardware failure or physical damage to the touch screen. It is also important to note that performing a system restore will undo any software installations or settings changes made after the selected restore point, so ensure you back up any important data before proceeding.
When should I consider professional repair for my touch screen?
If you’ve tried troubleshooting steps like updating drivers, recalibrating the screen, and performing a system restore without success, it might indicate a hardware issue requiring professional repair. Physical damage, such as cracks or water damage, also necessitates professional attention.
If the touch screen only works partially or exhibits other unusual behavior that isn’t resolved by software troubleshooting, it’s best to consult a qualified technician. Attempting to repair the touch screen yourself without the proper tools and expertise could cause further damage to your laptop.
