Hello guys,

I want to know what you think about leaving your computer switch on 24/7 in a company (75-150pc).  Have read some article on the net and it looks favourable.  I want to have your opinions..
Please post your comments...

We are all responsible for energy saving so I strongly recommend you keep your system in sleep mode, if you don't want to switch off completely. If you want to instantly turn on the pc the moment you are back at your desk.

I recommend these energy saving options :

Assign the power switch to sleep mode instead of turn on. So simply press the power button and it goes to sleep mode.

Put in sleep mode or turn off after half an hour of inactivity, so you don't have to remember if you did put in sleep mode.

At times you feel the system needs rebooting because it slowed down a bit you can do so as you require.

These options are good unless you have something running in the background always. , like some network rendering or remote access.

Most PCs stay on in our organization. I've noticed the older PCs often fail when powered back up, but otherwise would seemingly run forever.

Yes, it is recommended that your network devices should be up 24*7 but you can force PCs to be powered off when users left for the day or you can have more control through GPOs for it.

i don't see any reason to keep them running.
i suggest to power them down every day; a restart takes not more than 3-4 minutes
and by power off - i mean to remove AC from the systems (they keep using power, unless they're powered off by a switch on the PS) - if practical.
the older systems were manufactured with lower standards - and these were responsible for all the "power -up troubles". Modern systems don't suffer from it.

and it will show which pc's have "weak components" before actually shutting down during work.

also - they were not meant to be on 24/7  -like servers - they have different hardware, and software (housekeeping tasks)

It depends on the machines.  Some computers do not recover properly from 'sleep' or 'hibernate' modes and corrupt the files when that happens.  I have encountered that with some HP laptops that are less than 3 years old.

I think that consumer PCs should probably be turned off.  I don't think they were meant to run 24/7 reliably.  I turn all my computers off every evening.

It can be argued both ways.

One reason for keeping them running is thermal shock.  This occurs when the computer starts up and warms up to running temperature.  Wear occurs when this happens.  By keeping the computer running all of the time you avoid this.  See https://en.wikipedia.org/wiki/Thermal_shock  However you pay for this in power used.

I prefer to turn the computers off every night. This may not be applicable where you live but if there is a power flicker due to power issues or weather then you run the risk of having a computer fail. This could be something as simple as a power supply or something even more expensive to be damaged such as the motherboard. Shutting the computers off and all peripherals will also help cut down on energy uses and reduce electric bills. I would shut down the PC's and leave the servers/network devices running 24/7

>>  thermal shock  <<   that was true for the older pc's, but since then they are manufactured much better; +++ the software is better too.
i can tell you from experience : in the years 1990 - 2000 i had to come out every day for repairs, now it is  maybe 5 times per year

Based on the age of the equipment and power supply sized, you will reduce electrical usage by turning off the PC's If they are old and users complain it takes a long time for them to boot, then you might plan to leave those PC's on 24x7.

The bearing in your Power Supplies can wear quicker although a good quality power supply will last ten years.

It's a personal & business decision only you can make. We turn all PC's off when leaving the office to save electricity and wear.

Ok thanks for your comments. Assume that when i leave every computer switch on,  it will go on standby mode after 15 minutes.  I have also centralized ups.  So wht you think regarding power consumption? Is this still consume power?

After 15 minutes means that they will go on standby sometimes in the middle of the day.  My only concern is whether they will come out of standby reliably because I have had several machines that would not do that.

YES - it always consumes power; i even measured it on my PC - and different appliances  with remote control
you'd be amazed how much it takes.
on my PC it was  taking between 5 and 25 mA - at 220 V, which comes to 1 up to 5 W per HOUR = 12 to 60 W per day and per PC if you calculate an on/off cycle of 12 Hrs
