Discussion Overview

The discussion revolves around the question of whether it is better to keep a computer on continuously or to shut it down when not in use, focusing on the implications for the computer's lifespan and energy consumption. Participants explore various perspectives on the effects of power cycles, hardware wear, and energy costs.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants argue that turning off a computer does not damage it and can lead to a longer lifespan, citing personal experiences with older machines.
  • Others suggest that keeping a computer on continuously may cause wear on components due to heat expansion and contraction, although some believe this is a myth.
  • One participant mentions that turning off the computer can lead to wear on the hard drive due to the stopping and starting of the hard drive platters.
  • Another perspective is that continuous operation may lead to other issues, such as overheating or dust accumulation affecting the CPU and fans.
  • Some participants highlight the increased electricity costs associated with leaving a computer on all the time, with specific figures mentioned for monthly expenses.
  • There are discussions about the benefits of standby mode versus shutting down completely, with some users expressing frustration over technical limitations preventing them from using standby.
  • One participant emphasizes the importance of regular restarts for maintaining system performance and stability, particularly with Windows operating systems.
  • Concerns are raised about the environmental impact of keeping computers on continuously, alongside the financial implications.

Areas of Agreement / Disagreement

Participants express a range of views on the topic, with no clear consensus reached. Some believe that turning off the computer is beneficial, while others argue for the advantages of leaving it on. The discussion remains unresolved with competing perspectives on the impact of power cycles and energy consumption.

Contextual Notes

Participants mention various assumptions about hardware durability, energy costs, and operational practices that may influence their views. There are also references to specific operating systems and their behavior regarding power management.

Who May Find This Useful

This discussion may be of interest to computer users concerned about hardware longevity, energy efficiency, and optimal usage practices, as well as those interested in the technical aspects of computer operation and maintenance.

I was wondering if anyone knew if it is better to keep your computer on as much as possible, or is it better to shut it down when you are not using it? Will the computer have a longer "lifespan" if the on-off cycles are minimized vs. keeping it on all the time.

That's a myth. Your computer will be fine if you turn it off. I still have a computer that is +10 years old that I turned off every day.

One thing is for sure, your electric bill will be a lot higher.

$20/month/computer here in California according to my measurements. I'm pretty sure its more though because I didn't measure a few other things related to my computer (speakers, router and modem... and there's something else plugged in there that I can't see).

I would have thought that keeping your computer on would put more strain on the circuits... but oh well... aren't they designed to last decades now-a-days?
 
From what I remember, the computer has to heat up so the parts expand a little bit. When they cool down they contract again. Thus the constant retracting will damage them over time. However, I still think this is a myth. I've been into computer science a long time. I never have been able to find the validity of this.
 
I like standby.
 
For some reason windows xp (valid and upgraded) will not let me choose standby mode. The button for standby is there when i go to shut down, but for some reason it is dark or shaded and I can choose that option. I am only able to choose standby or shut down. Can anyone help here? Thanks.
 
I used to turn my computers off to get to sleep, but now I figured uptime is better than sleep. :)

Why would you want to leave your computer on 24/7 anyway?

what ?
your kidding right ?

some operating systems do perform maintenance routines at certain times (i.e at night). I just log out and switch the display off.

The computer could be a server of some sort.

turning on and off the computer brings the harddrive platter to a complete stop rather than just a slower revolution. everytime the harddrive is stopped, wear and tear occurs. for the harddrive, leaving it on is actually better.

leaving the computer on 24/7 may not be good for the rest of the computer though, especially if the CPU is v-modded or even just running hot. fans also will wear and more dust will be sucked in

Myth... does no damage at all...

Axeae... everytime you the arm moves in an Hd you get wear and tear

Does that mean that the platters gets scratched or something?

I turn off my computers at home and leave my one at work running, but log off. I think if you use it intermitantly throughout the day, it would be better to leave it on, but log off and shut down the monitor or let it go to sleep mode, mainly for a time saving. It's much faster to just log on than restart.

At home I go for hours between uses so I turn them off. I have a wireless network and it sometimes locks up on me if the computers are left on continuously, so I have to restart to reset it anyway. Does this hurt the computer? I have one that is over eight years old (a cheapy E-machine) that is still running great.

Not true, actually. Continuous POH (power on hours) is worse. Reliability is a function of usage, not non usage. Start/stop isn't an issue. The typical start/stop spec on a hard drive is in the 40k-50k range. Even if you turned your computer on/off 4 times a day (not so unusual for a laptop, actually), you'd get <15k in a 10 year period. By all means, turn it off.

Actually, there is another reason, not having to do with hardware. I always rest easier knowing that I boot up Windows fresh each day. We've all had situations where something goofy happens and re-booting fixes the problem. Whatever happened was obvious enough for you to notice. If Windows were to be left on all of the time, who knows what strange subtle thinks happen over time...

The longer you go between restarts, the weirder Windows gets.
It is best to give Windows a chance to stop all processes and restart fresh regularly.

With the exception of power failures or time-out for installations, mine is never turned off. The display shuts down automatically after 5 minutes of non-use, the HD after 10 minutes, and the whole system goes to sleep after 15. Those periods work best for me, but can be set to anything through the control panel.

current generation of computers idle wattage is about 200W maybe...more with the higher TDP processors like prescott/dual smithfields. help the planet, help your pocket, turn it off. if you have regular nightmares about shutting down too often killing ur data, one word: backups.

The heads never touch the disks, if they did, you'd get a head crash and probably goodbye to your hd, so i don't think scratching should occur.

I have a web server so i need to keep it on all the time. I noticed an increase in my electricity bill, but there's no other way, especially since the Windows Server OS when running as an Active Directory Server takes at least 15 minutes to shut down and 10 minutes to start.
