Many laptops have a keyboard key that turns the touchpad on/off. I looked at the user manual for yours and didn't see one.It's usually one of the function keys (F key) and is sometimes marked with a rectangle with a line thru it. It could have a loose connection and there always the possibility the touchpad went bad. Not real likely, but could even be a motherboard problem. Usually, there's also a setting in bios under configutation that affects the touchpad.
Make sure the touchpad hasn't gotten disabled in settings.

type

Pay attention to the scan results to see if SFC found anything it could not repair.
If it found corruption it could not fix followup with this command (note the spaces)
dism /online /cleanup-image /restorehealth
Restart computer
Just to verify, you DO see the Synaptics touchpad in device manager, correct?
