I factory reset my laptop (Lenovo 100s Ideapad) and now the trackpad isn't working, any ideas on getting it to work, please help?!

Added (1). I'm still on reboot page trying to put in details to load up the desktop.

Go to the Lenovo website and look for the trackpad driver.

Or if you're using Windows 10, leave the computer on overnight, connected to the Internet, and it might load automatically. Windows 10 does that pretty well!

Missimg device driver? Ask Lenovo for it via their support tab online
