Should Home PC's Be Powered On 24/7?

By pauly4190 ·
This is such an old and stale debate, I know, but humor me please...

I say stand alone home PC's (1.5 GHz and up) should be turned off at the end of the day or when it won't be used for several hours or more. A "rocket scientist" I know says allcomputers should be left on all the time irregardless.

I'd like to prove I'm right. Does anyone know of any websites with emperical data/polls proving I'm right?

The more prestigious or respectable the site the better.

TIA

Good luck. I don't think you will find anything definitive that relates specifically to home computers.

The issues involved usually come down to two primary factors:

1. Longevity of electrical components - electrical components suffer the most stress during a power-up cycle. The more often components experience this cycle, the more the effective lifespan of a particular component is affected (downward). This is usually the argument used for leaving computers on all the time. In reality, home computers are likely to become obsolete and be replaced before they are affected by shortened component lifespan. This same argument could correctly be applied to ANY electrical device. However, I have never heard any argument for leaving your stereo or TV on all the time. Their electrical components would suffer the same stresses.

2. Use of electricity - Turning off a computer when not being used to save electricity (and thus money) can be a valid argument (on the face of it anyway). What isn't usually looked at is "how much is really being saved?" Every different environment is going to give you a different answer. The power saved by a laptop user is going to differ from that saved by a minimal desktop user, which will differ from that saved by a user who has several computers with large monitors running. You would have to do a quantitative analysis of a given system (i.e. how much electricity is being used when a system is at rest - powered on but not being used)to determine how much is really being saved. You must then factor in the fact that the power-up cycle uses more electricity (at least momentarily) than standard use. Then you can determine the actual savings for any given system.

The bottom line is that it really comes down to personal preference more than anything else.

I don't have any specific sites with a definitive answer either.

Here are a few things to consider:

If the home PCs are connected to a always on 'broadband' internet connection, it increases your security if you shut them down when they are not in use.
If the PC is not on, it cannot be hacked.

Next, would be usage patterns.
Is the PC used daily?
If the PC sits idle for several days at a time, it would make sense to turn it off between uses.

What OS is installed?
Windows 95, 98 and Me relish, if not require, regular boots to clear up memory leaks and other problems from running constantly.
There is a documented bug in 95 for PCs that run continuously for 49 1/2 days.

Where I work, some PCs are on 24/7, others are turned off on a daily basis.

I see NO life or reliability issues from either option.

Again, the strongest argument for turing PCs off when not in use is system security.
If a PC is not on, it cannot be hacked.

The answer to this question has nothing to do with electrical specifications.
Many home PCs have cheap power supplies.
Many homes are "dust friendly".
Leaving the PC on 24/7 in this situation results in the insides of the PC becomming clogged with dust.
The trouble really starts when the Power Supply overheats because of lack of airflow, and the thermal cutout fails to open.
The resulting fire really stinks.
I have ignored the reliability of the fans, but it is another part of the problem.
Don't leave cheap equipment running unattended.
