reset computer without keyboard availability

i have a acer all in one computer that i need to reset and i can't press the alt f10 at power on screen because the computer wont acknowledge the keyboard plus the password to the computer has been forgottten so i can't even get past the log in screen...I know right only my daughter could do that.
