touch no responding all the time

Hello, I’m sorry to hear that you are having trouble with your Asus Transformer Pad TF103C touch screen. It could be either a hardware or a software issue, depending on the cause of the problem. Here are some possible solutions you can try:

• If you have not done so already, you can try to update the touch screen drivers and check for the resolution. This may fix some compatibility or performance issues with the touch screen. You can follow these steps¹:
  • Press Windows key and X on your desktop and click on Device Manager.
  • Expand Human Interface Devices.
  • Locate the Touch screen driver.
  • Right-click on the driver icon and click on Update Driver Software.
• If updating the driver does not work, you can try to calibrate the touch screen using the Windows settings. This may improve the accuracy and responsiveness of the touch screen. You can follow these steps²:
  • Type and search [Calibrate the screen for pen or touch input] in the Windows search bar, then click [Open].
  • Select [Reset], then click [OK].
  • The touch calibration has been reset to the default settings, please restart the computer and test the touch screen function again. If problems persist, please continue to the next step.
• If calibrating the touch screen does not work, you can try to open the case and re-seat the screen pig-tails. This may fix some loose or faulty connections between the touch screen and the motherboard. You can follow these steps³:
  • Turn off your tablet and remove any external devices or accessories.
  • Remove the four Torx T3 screws that hold the back cover of your tablet. You can use a T3 Torx screwdriver for this, which you can find here: T3 Torx Screwdriver.
  • Pry open the back cover using an opening pick or a credit card. Be careful not to insert it too deep or damage any components inside. You can use these opening picks for this: iFixit Opening Picks.
  • Disconnect and reconnect the two screen pig-tails that are located on the right side down under silver tape. Make sure they are firmly attached and aligned.
  • Put the back cover back and screw it in. Turn on your tablet and test the touch screen function again.
