Touchscreen not responding

First check your model has a touchscreen: touch models say "Touch" in the product title.

Quick fixes

1. Restart the computer.
2. Clean the screen with a soft, dry microfibre cloth.
3. Unplug the charger and test again. Some chargers cause erratic or "ghost" touches.
4. Remove a screen protector if one has been added, and test.

Turn the touchscreen back on

1. Right-click Start and select Device Manager.
2. Expand Human Interface Devices and find HID-compliant touch screen.
3. If it has a down-arrow icon, right-click it and select Enable device.
4. If it's already enabled, right-click and select Uninstall device, then restart.

Touches land in the wrong place

1. Search for Calibrate the screen for pen or touch input.
2. Select Reset if it's available, or Calibrate and follow the prompts.
