Been running 24/7 for 22 months straight and only has been turned off for heavy rain/wind storms where there could be a possible power surge or brown out. If i was leaving for a few days vacation I would shut the system down but other than that it is always on.
What is $30 month to run a 900 watt system ?? Seems like a cheap investment to me.
I don't shut any of my computers off, just let them go into standby / sleep mode.
Its not for any overly great reasons - just for ease of access.
It doesn't seem to be too hard on my electric bill, and I like being able to jump on a computer and look things up when ever I want to.
I will shut my laptop down if I'm traveling with it to conserve battery life. Also don't want it running while shoved in its case where the heat cant go any where.
I always turn off my PC whenever it's not being used for an extended period of time. Leaving a PC is the worst thing you can do. It acts like a dust filter and after a while the accumulation of dust is far worse on components and causes overheating. Having an SSD hard drive makes rebooting less than a minute.
In 2005 I worked as a security guard at a Power Station. Night patrols included a walk through the admin building which had all lights blazing bright. Of the 100 or so PC's about one third would be on showing a screensaver. No office staff were there of course, they all finished at 5pm. I doubt that that many PC's would have been left on to do important updates or anything.
I really see no reason to. I've seen no proof that my PC performs differently than if I were to shutdown. I've had more hardware failures on startup than during operation so I figure that's just a positive side effect. But I just don't like having to wait or make my clients wait. I'm On-call routinely for the company I work for, so having fast access to VPN in is a plus. I'll shutdown if I'm going to be away for more than a day or post updates to reboot.
I also reboot once or twice a week to keep the system fresh, but not a full power down.
I keep 30 to 50 windows open at any given time, and I am on the computer many times night and day, so shutting them down is a rare event. I don't know what it costs to keep our three computers running 24/7, but I don't think it is that much compared to the use we get out of them and that it is one of our few expenses we have for business and pleasure and don't mind keeping them on at all times. I would like to add that they are all energy star compliant, so they shouldn't draw much power in enery saving mode, and we don't let them hibernate either. Two desk tops and one small laptop. I think all three use less than 100 watts when in energy saving mode.
