Touchpad will move, but not click.

Hello,
My cursor randomly froze and would not move today, so I restarted my laptop to see if that would help. That time, the cursor disappeared completely, so I got my plug-in mouse and tried rolling back and updating the drivers for the touchpad. I got it now to where the cursor is visible and moves, but does not click. According to my drivers, they are all up to date. I am not very computer savvy, but have been looking up what to do online and this was what I was offered. Any help would be greatly appreciated.
I have a Lenovo ideapad 300.

You also might like to see if you disabled the Touchpad on your S300 Lenovo.

Press Red Fn key, between left control and windows key, while simultaneously pressing the F6 along the top of keyboard.

Above just breadcrumb trail.

Fn + F6 key turns on and off touchpad.

An icon should appear in lower right corner above task bar and clock with lines running through it, if touchpad is turned off by user.

Thank you, my problem is now solved! Going to Devices and clicking Alternate settings is what worked for me. I had disabled my buttons by accident, as I noticed that I could click by tapping the touchpad, but not with the buttons. Thank you!
