Talk about wasted oil imports, or coal or CO2 how about this.
I just check my power usage on my entertainment center with a new power
Sitting idle, turned off, not in use my tv, dvd player, satillite DVR,
and stereo are burning 40 watts. 40 Watts TURNED OFF! Takes 150 watts
That adds up to .55 cents a day, $16.79 a month, $201.48 a year. That's
If my light bill is $36.00 a month, by unplugging the power strip my
bill drops to $20.00 a month.
Think of all the entertainment systems in the country!? .37 KWH times
200,000,000; that's 74 million KWH!!!!
We are certainly not trying to save energy by manufacturing devices that
consume power when turned off. It's Nuts!
If your doctor isn't taking new patients,
he ain't curing any of them.
They call them power vampires:
says if off, average savings would be 0.08% per year.
I turn off what I can but cable TV boxes if turned off need time to
reboot and it is a PITA.
Depends on whether you believe that turning hard drives on/off noticeably
shortens their lives due to excessive wear patterns vs being green. My PC,
monitor and laser printer all consume 5 to 7 watts when in standby/off
If I'm goign to turn the computer off overnight I'd use Hibernate mode so
that when you come in next morning there's no boot up to wait for. Turn
computer on and everything is simply read in from storage on the hard drive
instead of booting.
This used to be the case a long time ago when HDDs were clunky and
prone to failure. No longer. I run my computer all day long and turn
it off every night. It's over 9 yrs old.
If anything is gonna fail, it's the monitor. I still use old CRTs and
I've been through 3 (all acquired used, mind you) in the last 3 yrs.
My next will be a LCD/LED/whatever.
How about backups? Don't you run those overnight too? Or do you just put up
with the added slowdowns that sometimes occur?
You DO perform periodic backups, right? For when you'll need it? So you
can recover in less than a half hour instead of a two day task and getting
all your customizations back? I let my backups run during the day; they're
smart enough to give over cpu time if something needs it.
Mmm, far's I'm concerned the jury's still out, which means the diffs
probably aren't great. Logic however says that, when the head moves and disk
spins, and that's true of a PC not being used because all sorts of
reads/writes still happen, there is an increase in wear and a resulting
displacement of lubricaton within the unit as it's pushed aside from the
movement of the heads and bearings. Then figure 5400 or 7200 or 10,000 rpm
drives and those on constantly are going to wear faster and displace
lubrication faster than when not in use.
So common sense says there is going to be a difference in wear between a
constantly ON and an ON/OFF cycled drive.
Do you mean to say that, 9 years ago, you set up a computer and that
today the amount of drive space etc. is still large enough? You must be
using this machine very sparingly and have very little data on the disk
drives installed 9 years ago! Gads, it must be running CP/M, DOS or win4wg.
Can other computers even read those drives, I wonder?
How about a description of that machine's specs and its drives? Mfg,
model, etc.. I'd love to know more about that machine.
Unless they're old enough to have the face retaining ghosts of printing,
used lines across it, I've never had a monitor go bad on my own machine/s. I
have an old win98 machine out in the shop I use for various shop-related
things and it's a top notch machine. It's even working with the original
tiny monitor supplied with it. It's probably only powered up two to three
days a week and it's turned off after every session (green attitude here).
On my good machine I have policies set to turn it on every morning
before I come into the room and off a little after bedtime so I'll hear the
announcement. On top of that, my disk drives spin down after more than an
hour of idling, followed 5 minutes later by the monitor with one of its
If anything's going to fail, it's most likely a fan IME. Many people pay no
attenton to dust & dirt inside their machines & thus the fans & slots for
them get fouled with crap making them ineffective and thus they'll
eventually fail completely unless another component shuts down due to
excessive heat, although the problem is still a fan/s.
I have two. One is shut down when not in use for a long period, say more
than a few hours. It is usually used once a day soit is shut down for the
other 18 to 20..
My main computer is never turned off, but I put it in sleep mode. Given
that it shuts down the fans and HDD, it has to save some power. Takes about
10 seconds to come back up. I can go for weeks between re-boots.
that is true for high heat, however, changes of temperature is a larger
enemy. one of the reasons why computer rooms are so tightly temp controlled.
things expand/contract as they heat up and cool off, causing physical
changes and stress fractures over time. it is FAR better for longevity to
leave them running than to power cycle them daily.
working for a computer company, we see more hardware failures on powerup
than during normal operations. our computers are currently seeing between 6
and 7 9s for uptime, so they run for quite a long time.
I turn my computers all the way off when I'm through using them. It
could be several times a day depending on what I'm doing. I'll leave
a computer on if it's running a defrag or anti-virus program but I'll
usually shut it down when I'm done.
I've had to repair too many machines that people walked off and left
running. Most of the time it's due to the fact that a computer acts
like a big vacuum cleaner sucking up every bit of dust in the room.
The only computers I recommend to be left running are the servers I
build for myself and customers because those machines are designed
to run 24/7. I install external air filters that are easy to get to
and clean especially on the rack mount systems. It's amazing to me
that for just a few dollars more, I can get components with a much
higher MTBF rating than standard desktop fare. The workstation I'm
using to write this is a Dell Precision 390 and I don't even have the
hibernate mode enabled. It takes 1 minute 50 seconds to fully boot
from off including me typing in my passwords that allow it to boot.
One thing I've been repairing is lightening damage to machines that
should have been turned off and unplugged before the owner wandered off
somewhere for half a day. It's happened three times to one fellow I
fix and maintain computers for. I keep warning him about his power
wiring and the improper grounding but he's hard headed. ^_^
But they aren't truly unused; they're saving preprogrammed data and the
other aforementioned annoyance of slow on-time, etc., etc., etc., ...
If you want to try it and see how you like it the other way, put them on
a power strip and turn 'em off and see how that goes for a while.
There is no free lunch; you're paying for the convenience and the
facility to have those kinds of entertainment devices ready at hand when
wanted. (I'll not discuss whether that's a need or not since I'm the
type who's yet to program the VCR (which hasn't seen more than one or
two uses in its life) and don't have DVD other than the drive in this
machine which has, as far as I know, never had a DVD played in
it...altho I might be getting ready for the first; I bought a Leigh
dovetail jig the other day and I just _MIGHT_ try to watch a little of
the instructional DVD... :) ).
Only $.059/kwhr!? Again, where do YOU live? We pay $.14 kwhr.
As for the vampire thing, start walking thru yer house. Clock radio,
night light, electric toothbrush, cordless phone, lighted doorbell
button and light swithces, microwave, digital clock on stove, blah
blah.... ad nauseum.
It's positively shocking how much crap we have leeching pwr 24/7. The
power companies love it. ;)
