Default Leaving a Computer on All Day vs. Turning It On/Off Everytime

So how many of you leave your computer on all day (screen saver or not)...and how many of you turn it on and off every time you use it?

Pros and cons for both?

I assume if you are at work, you can't turn the computer off at all, but how about all you other people?

Some people say it's not a good idea to turn it on/off all the time, and some people say it's not good to leave it on all day.

Answer me!

heh.

I leave it on all of the time. I have it set to power down the monitor after 15 mins of inactivity, and power down the hard drives after 1 hour. So, it's pretty much as good as being off during those times, but certainly takes far less time to reactivate as compared to rebooting it.

I know when I was running my computer overnight, my energy bill went way up

Screen savers don't make a difference; monitors nowadays are immune to "burn-in" for the most part.

I usually leave mine on for several hours, and turn it off when I leave or sleep. It can't add to the longevity of the parts to leave it running 24/7. But what do I know

The old argument is that turning the computer on and off causes more wear on the mechanical parts (hard drives, fans, etc) since the most stress is on startup.

In my experience though, it does not seem to make a difference whether you leaving your computer on 24/7 or whether you turn it on and off when you need.

Personally, I turn mine whenever I first use it after work and then it stays on until I go to bed...unless I go out or something, then it gets shut down. The monitor powers off after 15 minutes, and the rest goes into stand by after 30.

computers can run for a long time without being turned off, like years. As long as the fans dont go out it should be OK. I use STR (Suspend to RAM). All power is turned off except for enough to retain the memory, but it will turn on instantly.

Agreed...and nowadays it's pointless to argue either side, since the parts will last at least 5 years under most conditions, which means they will be outdated by at least 4 years when they break...

...and then the users get pissed if you try to push out patches during business hours. Damned if you do, damned if you don't.

When you are done using the computer turn it off. Its not like the computer is going to stop working all of a sudden because of the increased stress to the system during startup. If you turn it on and off 4+ times a day then yeah you should just leave it on all day.

Ummm... no. I have a monitor here at work that has been burnt in because we never had it go off. After a few months of the same screen we now have windows 98 as a ghost image on it...

I personally leave my work one on 24/7/365. My home one I don't use too much so I power it on and off.

Maybe it's really old or crappy? I can't tell you exactly technically, but there are several different methods used in display technology nowadays that are not succeptable to burn-in simply by the virtue of the way the monitor is displaying the screen. Obviously your monitor at work does not use that technology :shrug:

Upgrade your RAM you freak!

--------------
At work it's 24/7/365. Some have screensavers, but all turn the monitor off within 30 minutes. Most turn off the harddrive, except the servers.

At home it's on only as long as I'm using it. If this means I turn it on when I wake it, somewhere in the afternoon. In the evening to check something before I go out, and later on before I go to bed, thats fine.

As an engineer at Seagate I feel qualified to respond to at least a portion of this question.

My understanding of the original reason that leaving a computer on all the time was a good thing, was that early hard drives often had a 'stiction' issue. That is, if the heads came to rest on the disc sruface too many times, sometimes they'd never be able to take off again.

Some old timers may remember the need to hit an old computer on startup. Literally, a firm tap on the case with a blunt object would sometimes get a computer with an offending hard drive up and running.

I'm talking about very early drives. 20-80meg vintage hard drives or so. Things got better quick. 500 meg hard drives were much better with this kind of thing, and 2 meg+ drives are pretty much impossible to have these issues. But, the 'keep power on all the time' mentality had already been engrained in users.

Nowadays, this is a total non-issue. Hard drives are designed not to have these issues for literally millions of start/stop cycles.

I turn off my computer at home all the time. No reason to leave it on, and it draws power. At work, I just suspend it overnight. I hate booting every morning. I'd much rather just come in and start where I left off the last day.

As for screensavers. CHEAP LCDs will burn. CRTs will burn too. Monitors are more resistant to it than green screen Apple ][ days, but I work in a factory where many computers show the same screen 24 hours a day. Put that screen on a different computer and you can clearly see the burn marks, usually, even when the monitor is off you can see them. The cheapo LCD screens we have around seem worse than the CRTs.

I think there was an article a month or so ago about the LCDs in Dell laptops being prone to burning.

Hopefully I won't have that problem with my 23" Apple HD LCD.

I leave my computer on 24/7 except when forced to reboot (e.g. loading a new linux kernel); I turn off the monitor when I won't be using it for a while (e.g. during workday hrs, at night when sleeping).

I turn my WinXP box on / off as needed ... it's a BookPC so has an annoyingly loud fan ...
