I switch off my computer twice a day or so because I do not use it for
many hours and would do well to save the electricity. I opted for a
fast computer with a huge display instead of one I could just leave on.
Anyhow, I know how much a computer costs me per day so let's not argue
over it, because I had measured it and multiplied and know what I want
with the current setup I have.
The question is, does frequent rebooting harm a computer? The reason I
ask is that now I'm considering a linux livecd so that I could do some
work with it without the distraction of my regular installation of
windows. I would not be able to get online with a linux livecd (let's
not argue over it, i won't on my computer) so there's no web or instant
messaging, no movies, and all I could do is edit text like I should be
doing.
Would 4 or 5 reboots per day harm a computer? In particular, the hard
drives? or is it somewhat harmless?
By rebooting i mean orderly rebooting, from clicking shut-down in
software, not switching the thing off from the mains or pushing reset.
As a lot of people have pointed out, system life is almost negligable to
consider, cycling may well reduce life span, but whats the point if the
shortened lifespan is still longer then your typical replacement interval?
I personally do upgrades every 18 months or so, and a new system every 3
years or so.. If powercycling reduces the lifetime of the system to five
years, i don't consider it as significant.
Personally I leave the system itself on at all times, it might get shut down
twice a month, typically for updated stuff that needs a reboot, i'll just
shut it down at night instead of walking away from it, and let the reboot
happen when i restart in the morning. Typically when I am going to be away
from the desk for more then an hour or so I turn off the speakers and
monitor, printer is OFF unless needed. Having the system continue running
has added only slightly to my monthly power bill, and may well be negligable
come winter when the heat produced by the system is sufficient I won't have
to run my heater very often (Phoenix arizona, ran my heater maybe a total of
twenty hours last winter, but then again my downstairs neighbors did most of
my heating!). I leave my system on tho so that the TV tuner card and it
associated recording software can do their magic and grab some of the late
night repeats of daytime programming that conflicted with other recordings,
it typically snags about an hour of TV each night for me, usually from the
discovery channel. I don't know how much power draw it pulls when the
monitor and speakers are off, but at the end of the month the bill isn't
much bigger then it used to be so I don't worry about it. If you are
concerned about power consumption there is a little contraption out there
that you plug into your wall, plug your system into it, and it will report
volts/amps/watts etc that is being drawn through it. Think some even
measure kWh for time based measurements. Find one of those little jewels
and try it out, see how much power us used during each cycle compared to a
running system, startups do draw more power, all that static friction to
overcome in the moving parts bringing them up to speed, lot lower power
demand to keep them at speed. Additional power demand by processor
depending on what its doing at the time....
My laptop on the other hand... gets hibernated when I am more then twenty
minutes away from it... why? Cus i don't need it ot be running full time,
and its ancient, nearly six years old, everything in it from teh factory
except for a hard disk i replaced last year (think my fujitsu travelstar
10GB it came with lasted ALMOST to its 5 year predicted lifetime).
Bottom line... if you ask two different people this question you will get
five different answers, choose what works best for you and stick to it.
