Thanks again, guys.  The collective knowledge of this group continues to
amaze me.  What a great resource.  It's one of the reasons when I get a new
notebook next year, it will almost certainly be a ThinkPad.  Despite the
limitations of the current models (I'm looking at the W520 which has 9.5 mm
hard drive height that prevents larger than 750 GB drives, no Blu-ray
optical, and while USB 3.0 on the machine, only 2.0 on the docking station),
the keyboards, the service, and this group keep me from looking elsewhere.

Chip failures are really weird, and not as well understood as a lot of
people would like.

Sure, temperature can cause problems over time, but in the case of the
Nvidia GPU, the phrase 'time bomb' is pretty much correct.  I had three of
five thinkpads with them fail, with the 4th crapping out and I still haven't
gotten my hands on it.  So yeah, Nvidia made a turkey.

I think wikipedia might have some stuff on IC failures; look at
http://en.wikipedia.org/wiki/Integrated_circuit and go from there.

Yes, your 5th year was a good investment.  ;-)
