The argument also goes that you should never turn off your computer explained
that while operating all of the electronic components heat up and expand, then
when you turn them off they cool and contract, thus reducing their lifespan by
subjecting them to greater stresses than if they just heated up and stayed
expanded. Obviously doing this with a PB would be impossible, but I wonder what
effect this kind of radical temperature cycling would have on a CPU's lifespan.
I don't necessarily subscribe to this theory, but you should be well informed. I
do however try to avoid shutting down my desktop unnecessarily during a work
day.
