When I was going to community college for computer science
and electronics, in both computer hardware class and digital
electronics class, they taught us that frequently turning a
computer on and off was very hard on them. The capacitors and
transistors take a hit from the power surge everytime it gets
turned on, and wear from the heating and cooling.
Agreed. But this also applies to every electronic device, radios, TVs,
VCRs, CD players, car computers, etc. There is no reason why a home
computer should be especially sensitive to being switched on/off. And if
heating and cooling are going to damage the CPU then it will get a lot
more when it switchs between low and high speed. Glenn McCorkle's
figures for the core temperature after different modes of working show
how hard this might be on the CPU.
Also the
harddrive is especially hit as it swells and shrinks from the
heating up and cooling down, which is also hard on the magnetic
data points, this can also lead to possible data corruption.
The hard drive would be hardest hit only when it is accessed for reading
or writing. I am not at all sure how much its internal temperature
changes at these times, but if it does alter very much, then by your
reasoning it should be kept PERMANENTLY in a read or write state to
avoid these temperature fluctuations.
They also stressed though that leaving them on continually will
waste a lot of power, especially in big companies with lots of
nodes. They had done considerable research on this.
Who was this that had done "considerable research"? Was it practical
testing or just reading any existing literature?
I think the
best thing to do is find a balance between each individual one's
use and nonuse of their particular computer usage.
Yes.
