WiFi, screen orientation, and pen button constantly flashes

Has anyone ran into this problem? My wifi whole program completely disappeared… I can't change the orientation of the screen… and the button you press to switch to use pen on the keyboard.. is constantly flashing and doesn't let me switch to it.. I've tried EVERY reset way you can… it does show theirs disc errors that are repairing and will take hours but only runs for maybe 5 min and doesn't change Anything…please help with what I need/can do to fix this or if I'm S.O.L and is garbage.. this was my favorite.. coolest laptop I've ever had…

Thanks in advance…

Matt
