Windows 10: Touchpad stopped working

On one of our laptops, the touchpad stopped working. A wired USB mouse does work. Touchscreen still works. After a lot of troubleshooting, my suspicion is that it's a mechanical problem with the touchpad. Here's a summary of what I did, but let know what you think. 1. I opened device manager and under 'Human Interface Devices' updated drivers for HID-compliant device and HID-compliant touch pad. 2. I deleted the HID-compliant touchpad and tried adding the driver back. Is there anything else I can do? What are the chances that the actual touchpad is malfunctioning?
