The hard drive failed, and was duly replaced under warranty. Now I just noticed the top edge of the plastic that surrounds the keyboard is coming apart. Now this machine is lightly used by a mature responsible guy who takes care of things. If the machine travels it has it's own special padded bag. I have an IBook and a PowerBook and this MacBook really is a sad piece of junk. it's still under warranty I'll see what they say. This is becoming a PITA. I wish I'd bought a Lenovo now.
