Touchpad and keyboard not workin

KMS1974 - Nov 28, 2015 at 07:56 PM
My mom has an Acer laptop and upgraded to Windows 10, unfortunately it slowed her laptop so much she wanted to downgrade back to Windows 7.

Since trying to do so, the keyboard and touchpad will not work even in safe mode.

I've tried looking for simple answers but to no avail.

Could someone please help
