Fix Windows 10 Touchpad Issues
Touchpad issues can either come from the hardware or the drivers powering it in Windows. Once you track down which it is, solving the problem is straightforward. These steps can help you narrow the cause and get your touchpad working.
Confirm that the trackpad is connected properly. If your touchpad is not working, make sure it's connected to the Windows 10 device properly. If you use a touchpad that connects through USB, check that both ends of the connecting cable are fully plugged in.
If the touchpad is part of the keyboard, like with the Type Cover on the Surface Pro and Surface Book, make sure that the keyboard is completely connected to the tablet with no foreign objects obstructing the connecting prongs.
If your touchpad and keyboard are built into your system (like in a laptop/notebook), this is more difficult. Skip to step 5; if the further steps do not help your issue, you may have a hardware issue and may want to bring your system to a computer repair shop.
Remove and reconnect the touchpad. Unplugging and reconnecting the touchpad may fix connection issues. If you use a Type Cover on a Surface device, this can be done by disconnecting and reattaching the Type Cover.
Check the touchpad's battery. If the touchpad connects to the Windows 10 device using Bluetooth and it stops working properly, its batteries might be running out of power. Replace the old batteries with new ones to see if this fixes the problems you experienced.
