content: I have mine set to go to sleep after an hour, and it goes to sleep sometimes, so the 5V standby on the PSU is running, and the RAM on the mobo still gets power.But I wonder side by side these days which PC would last longer, the one you let go to sleep, and or shut down all the time, vs the one you just leave on.

content: Screen goes off after 10 mins (mainly to save replacement cost). Entire setup has power removed every night, so that's a bit more frugal than mere 'sleep'

content: I probably sleep my PC about 5-10 times per day, it's fine. It is all SSD though.There is probably very little difference in longevity. In favour of sleeping would be lower thermal dissipation on components which extends their life. In favour of keeping the PC on would be less chance of data corruption due to poorly-behaving programs, and less cyclic loads on the power supply.I would argue the power bill favours sleeping the PC. My PC uses about 150W in operation - at current UK on-peak rates that's 5 pence an hour. So if I leave it running every night for a year (10 hours per night), it'll cost me £164 in electricity. That's not insignificant, and I haven't put anywhere near that in replacement hardware in to my PC. The last failure I had was a graphics card which was still covered under warranty.

content: My desktop goes to sleep after 30 minutes.When i first got my machine i had to disable sleep mode, because in 95% of cases it would not wake up anymore.Since a windows re-install a year later (for unrelated reasons) it works totally fine.But when i am done for the day, or will be away for longer periods, my machine gets shut down.

content: No sleep for me. Only the monitor turns off after like 15 minutes. Other than that the computer is running or I turn it off.I have not tried sleep in many years but when I did with win XP i had some trouble. Now I am using Linux but I still do not use sleep.

content: I do use standby and practically never turn off computers anymore now, unless I'm away for more than a couple days. I don't let them go to standby by themselves ever, though, for the desktop computers, only for laptops. (I do for the displays.)So I just put them to standby when I leave, instead of shutting them down. Avoids having to wait for rebooting and setting back your session as it was for getting back to work - it doesn't look like much, but always annoying.Using standby also on Linux, absolutely zero problem here. But the typical number of cycles per day is 1 to 2 for desktop computers.Unless you have many standby/resume cycles per day and you use spinning HDDs, it can only make your hardware last longer. (And even with HDDs, it would take a lot of cycles to even shorten their lifetime.)If you have a dodgy PSU, it may shorten its lifetime a bit, maybe, but if it's a decent one, it can again only make things better compared to letting it on 24/7.And of course there's your electricity bill.

content: Quote from: SiliconWizard on January 08, 2024, 12:17:08 amA while back I was putting one to sleep and never turning it off - that was my plan. But I would see in the morning many times it was not sleeping but full on. I thought the sleep function was buggy or something ... wait it looks like the mouse has been moved?Oh kitty cat! He was checking things out at night and he moved the mouse. Since in the bios I had "wake on USB event" enabled he was able to turn it on.

content: Quote from: xrunner on January 08, 2024, 12:31:23 amCats can be an issue with it.Note that not all BIOSes and mice act the same relative to waking up. With some mice, just moving them around is enough to trigger a wake-up event, while with others, you need to click on a button to do so. I try using mice which only do the latter. But that's something you won't know until you try...

content: Sleep working well depends on your motherboard, some motherboards have zero issues with it, others have issues occasionally when coming out of sleep, and some are just terrible.If you have issues with sleep you can use hibernate instead and it should work flawlessly.With an SSD the speed to hibernate and resume is fine. It's only bad on spinning disks or if you have a butt load of ram.With spinning disks it's best (for longevity) toleave them spinning rather than letting them power down and up on activity + timeout.either disable the spin-down timeout entirely or set it to something much larger, like an hour or two instead of the default, which is usually like 8-15 minutes.The starting/stopping wears the motor, bearings and loads the motor controller with lots of inrush starting currents, and the thermal cycling isn't good on other parts either.The feature for power up/down on activity was added for environmental reasons so they can quote a lower average power consumption.

content: Quote from: Psi on January 08, 2024, 05:43:07 amDrivers can also be a huge issue.I have an AMD system, CPU and GPU were relatively new when i got them, and the drivers apparently were not all done yetThe system went to sleep jut fine, but it could not wake up.You hit the button, lights turned on and fans spun up, but apart from that nothing happened and i had to force power off the system.I disabled sleep when i was not able to find a fix and got used to sleep not working.About a year ago, i reinstalled windows, with all new freshly downloaded drivers. I forgot to disable sleep again and was already annoyed when i noticed the system asleep. But to my surprise it woke up without a hitch. And it has done now everytime, not a single crash happened.I have not made other changes to the system when i reinstalled.Regarding systems waking up unintetionally: My recommendation would be to disable "wake by" for almost everything. Especially wake on USB can be very finnicky with some peripherals. Give me an old school press of the power button everytime

content: Another reason that I do not use sleep on my laptop is that it cold boots faster than it wakes up from sleep mode. The only reason to use sleep mode is if I want to keep applications open.As an aside, my laptop and modern desktops cold boot faster than my Android phone. My laptop is especially fast.

A simple thought experiment suggests it isn't true for all cases (5 mins run time every 20 years, for example) so there should be some point where best practice changes from turning off to leaving it on.

content: Quote from: PlainName on January 08, 2024, 08:42:13 amI would say it is heavily dependent on the use case. A computer that powers on/off several times a day might be a problem, as the startup current on HDD motors is much higher than nominal, according to a resident expert that used to work on this industry. However, this is certainly not true for very lightly used servers - our NAS sees very little activity (accessed once every few days) and there is no scenario where leaving it powered will extend its life, as bearings will be the dominant wear factor.

content: Sleep mode is not off.Even power off mode is not really off.If you want a computer to be really shut off, you need to connect it through a power strip and turn that power strip off.Even that does not work for a lap-top. I think there you would need to actually remove the battery.

content: No need to remove batteries. In a laptop you put it down by issuing a "Shut Down", not an S0 "Modern Sleep Mode" which can apply updates and bring up the computer without your knowledge. i have been using Windows 10 and 11 for quite some time now and this effectively prevents any computer activity.

content: Is motor failure of HDDs a realistic risk? It's my understanding HDD failures typically occur for a few reasons:a) Head touches disk surface due to excessive vibration/physical shock/bearing failure;b) Too many sectors become irretrievable, leading to breakdown of the filesystem, possibly due to (a);c) Disk controller failure for unknown reasons, ESD/power supply issues, random silicon death etc.I haven't heard of motors failing. Typically, one would expect a brushless motor to survive hundreds of thousands of hours. The bearing is a risk, but I think it should be well established now how to make these bearings last a very long time given the precision elsewhere used in hard drive manufacture.Spinup/spindown shouldn't correlate strongly with HDD life in "normal" applications (shutting down disks on idle) IMO.

The motors do die, but motor controller death is far more common.Quote from: PlainName on January 08, 2024, 08:42:13 amThat is true, but in a typical use case when you have the feature enabled you end up with many more on/off cycles than you would have had with the feature off.Perhaps i should have added "for a typical use case" to my previous comment.There is also the annoyance of the ~2 second delay when you click on the drive in windows explorer and it locks up waiting for the drive to finish starting and become available for access.Sorry I dont have any reference,

content: Aren't most things prone to failure when powered up? So not turning them off makes sense on that basis.But... electrolytics don't have a finite life, so leaving them on may wear them out. And, probably, any issue with those would be noticeable when starting up whereas the same fault wouldn't cause a shut down once working. Similarly, disks may be borked but limping along, and it's only when you try to cold start them that they actually show how bad it is. So perhaps it's not that clear at all.

content: With spinning disk drives, how long they last is surely related to how they are used. I have a server for archival purposes, it can be days between times when it is accessed. Sometimes even as long as a month. There is no way I can believe that leaving the drives running constantly will make them last longer than if they are shut down when not needed.

content: Quote from: rdl on January 09, 2024, 04:31:24 pmYep, how many times the data is being accessed each day is the key.They could be doing spin up/down/up/down/up/down 100 times a day, or once a day. etc.. depending on what your doing.My only real point was that excessive spin-up spin-down is not good, and IMHO the default time to spin-down is way to short, especially on some drives like WD green's.
