Hello, I am having a lot of trouble with my touchpad. My device is a Lenovo yoga 13 with Windows 10. For some reason, the touchpad does not work. I've looked everywhere online. I've uninstalled and reinstalled touchpad drivers multiple times, restarted my computer, checked the BIOS, and scoured the internet. None of the answers I've found help. my touchpad doesn't appear in device manager, there's no touchpad option in mouse properties, it's like my computer never came with one. USB mice work though. The strangest thing is, it turns on randomly and works for a short period of time. I've looked at the fn control keys and I'm not turning it off. help is greatly appreciated.
