[dba-Tech] Always On Notebook

I haven't looked at our rates for a while but the last time I looked it was
about $.23 per kwh.  How does that compare with yours?

$15/mo/computer seams to be pretty high. But I don't know your electric
rates, what is it per Kilowatt-Hour (kWhr). The ongoing heat might depending
on the design degrade the plastic parts. It is actually the inrush current
that kills the most electronic parts during power on. The bearings of the
hard drives shouldn't represent a problem it is a more likely problem that
the read/write heads stick to the disk during power off which get damaged
during power on. I have 5 desktop PC's running at my friends company for
over 11 years 24/7/365 without any problems. I bet you, that if they would
have switched them of every day they all would have gone broke for one or
the other reason mostly for electronic failure due to the inrush current.

Perennial question - is most of the wear on your machine due to the heat
that degrades the components over time until one of them fails?   Or is the
most wear due to the surge of power when you turn it on and the stress on
the bearings on the hard drive?

I turn off my computers at night (actually go to standby so they start
faster).  I once figured it saved about $15/mo/computer to turn them off a
night but San Diego has pretty high electric rates.

I've grown into the habit of leaving my notebook on 24/7. It's using the
power supply, of course, not the battery. Is there a down side to this? will
the machine wear out more quickly because of this? Even though it's a
notebook, I rarely move it, so I just leave it running.

TIA,
Arthur
