Right, so I turned off my laptop and came back to turn it on after 1 hour. Now, the keyboard and touchpad work fine UNTIL the welcome screen, where if I press any of the letters, the entire bottom half of the laptop (function button, letters, pretty much everything except monitor) becomes disabled. During that time, however, I can use a USB mouse. Any help on this?
P.S. I have a password on my computer so I can't even get past the welcome screen.
