My Tablet PC's Touch Screen is Not Working
- Damages to the surface of your Tablet PC can cause the touchscreen to malfunction or stop working entirely. For example, putting pressure on the screen, such as placing the Tablet PC in a bag with other heavy items, can cause cracking along the screen. Exposing the screen to water, even in small amounts, can cause the electrical system within the touchscreen to malfunction. If the electrical system malfunctions, the touchscreen stops working properly.
- Pressing the touchscreen on your Tablet PC sends a signal to the internal motherboard. The motherboard then transmits to other components, such as the hard drive. The accuracy of the touchscreen depends on the screen's sensitivity. Many Tablet PCs include a program for calibrating the touchscreen. This program may fix minor responsive issues.
Even a small amount of dirt or debris can effect how the touchscreen responds. Cleaning your touchscreen with an electronics cleaner or a microfiber cloth may help improve sensitivity. - A driver is a software program that interacts between hardware devices and an operating system, Your Tablet PC needs the right drivers for your OS to work correctly. Outdated or missing drivers can cause the touchscreen to work improperly, or not respond at all. Visit the manufacturer's website to find the right drivers for your Tablet PC.
- While you can perform some minor repairs yourself, such as re-calibrating the touchscreen sensitivity or installing drivers, only perform a hardware repair if you have a good working knowledge of electronics, specifically Tablet PCs. Before attempting to repair your device, contact your manufacturer. If your Tablet PC has a warranty, completing an unauthorized repair may make you ineligible for claiming that warranty.
