Leave it on or leave it off - kap - 05-15-2008
Is it better (hence long lasting) to leave our PC desktops on all the time? A good friend who is a programmer at SCE already told us that it costs us very little.

with modern LCDs instead of CRTs, and deep sleep mode, I just sleep mine (or let them go to sleep)
My old machines with CRTs or those that don't deep sleep, I power them off.

Leave it on. sleep more works very well

I sleep mine as well. But there are a huge number of things that get fixed every time I restart my Mac every few days.

I vote for the sleep as well.

Is power your main concern? What kind of PC?
While LCD's *generally* use very little power in low-power/sleep mode, computers often use a significant amount of power even in low power mode.
Computers (and obviously laptops) that use laptop cpu's and have the appropriate software running on them *may* use very little power when asleep, but you can't count on it.
I suggest that you get a Kill-o-Watt and see for yourself what the difference is between active and sleep-states.

If your concern is wear and tear on the PC, I wouldn't worry too much about it. The average upgrade-cycle on a corporate PC is somewhere between 18 months and 2 years. If it's leased, maybe you've got 3 years. The components you're stressing with the power-cycling -- whether shutting the thing down or sleeping it -- are probably going to last more than 3 years on most of your PC's even with the additional strain of the rapid heating and cooling, spin-up, etc.

Yeah. I will ammend my answer to include that I do a full power down, and restart every 10-14 days. 2-3 times a month basically, and I run Onyx and Disk Utility then.

All current Macs support deep sleep. In that mode, none of them uses more than a few watts.
Mac Pro -- 7 watts
iMac -- 2 watts
Power Mac G4 "Sawtooth" -- 4 watts
That's "night light" territory...

My Beige G3 had a "sleep" mode, but I didn't seem to be anything more than shutting off video output. Power supply fan remained on full even in sleep.
But yeah, the new ones are much much better.

Our machines are always on. Our "media" G5 is set to never sleep and hard drives to never spin down. My MBP is always on - restarts for software updates or kernel panics. My work PC is set to never sleep, as I need to RDC into it frequently.
