Do you leave your computer on all the time or switch off after use?
Posted 06 July 2011 - 07:27 PM
With power bills increasing and climate control making headlines, I'm wondering who amongst us worries about how we use our computers - are they really smart enough nowadays to shut themselves down and use no power or are we actually using more power to start up our machines a few times a day than it would take to leave them on 24/7?.
Your vote and opinions, as always, welcomed

in order for me to save the planet and those who would inherit it, etc, etc,
After fitting it & watching your power consumption, you will learn that switching
off your computer or laptop when not in use is quite a good idea !
Problem solved, I saved the world !

One of the most common arguments for leaving a machine turned on is that the constant heating/cooling cycle will eventually cause solder joints to crack and subsequently, poor or zero connections. I doubt that would actually be the cause of too many breakdowns.
One of the main arguments for switching off is because leaving it on will consume a lot more electricity. Seriously????? Have these people never heard of "Power Plans"; sleep mode and hibernation?
Me, I leave my computers switched on all the time. The only times I ever switch them off is:
1) If I am going away for an extended period and
2) If there are thunderstorms about.
That said, I do spend a lot of time on the machines and so it is mainly for convenience.

Suffice to say, technology and reliability has improved tenfold since then, but if we're talking about which is best for your computer I personally would opt for leaving it on and allowing the machine to manage itself, if we're talking about power consumption then it would have to be to shut it down.
Sleep mode, hibernation and any other form of standby facility will consume power from the mains, the exact amount of which I couldn't say with any certainty, but it stands to reason that unless a machine of any kind is completely powered off it will have to use some power to be in a position to 'resume' from where it left off. Laptops can pull from it's battery power without a main charge when in hibernation but it will only be able to do this for so long before finally loosing it's state when fully discharged.

Well...You're obviously not going to see spikes if it's on all the time - spikes (or the opposite - dips I guess?) occur when you change the average uptime of your computer. Your computer remains steadily on all the time; thus, your power bill will stay steady.

Actually...wrong. Standby does use power, but hibernation uses no power. The reason for this is that standby stores your computer session in memory, and your memory chips go blank if they lose power. Thus, standby is a low power mode that retains just enough power to keep the session stored in memory intact. Hibernation, on the other hand, writes your session data to the hard disk, which, of course, retains its data even when the computer is turned off completely. That way, hibernation can have the PC completely shut off. That is why it takes longer to enter hibernation than standby, why there is a file in your C: drive called hiberfil.sys that should be the same size as your installed memory, and why it takes longer to go into hibernation than sleep or standby mode. For more info on this, see the Wikipedia hibernation article.

Maybe you should look into eliminating some of the startup crap...or upgrading

And. to be pedantic. unless turned off at the power point a computer still uses some power irrespective of what mode it's in, and there
are all those transformers for the speakers, printers.scanners, routers, external Drives all adding to global warming which are seldom disconnected.

One thing that does need to be pointed out here: In 'shutdown' state a desktop computer is still consuming power, and the difference in power consumption between shutdown state and hibernation or sleep mode is so minor as to be completely negligible.
The only way a desktop computer will consume zero power is to switch it off completely, either via a PSU switch or at the power point.
So, when we say "switch off" we are talking about completely switching off and not merely using the "Shut down" option in Windows.
Another point for consideration: We do not completely turn off other electronic entertainment devices such as TVs, DVD players, home theater equipment, etc. When we click the power button on the remote control, those devices stay in stand-by (or readiness) mode and are still consuming a small amount of power.
Also, in terms of power usage in the average household, the home computer would be very at the very bottom of the power consumption chain.
Not debating one way or the other here, just putting forward some observations for consideration.
