I reboot only when the computer crashes itself. :badpc:

Twice a day. Turn on at 6am turn off when I go to work around 7.15am. Gone all day turn on just after 5pm turn off when I go to bed. Don't leave it on when I'm not home no point all it does then is use a bit of power

School days: sometimes goes on in the morning before school, then gets shut down before I leave. Always started when I get home from school.

Weekends: Turned on in the morning and left on for most of the morning/day, then switched off overnight.

I don't bother rebooting for updates as a shutdown counts. My netbook is turned on when I need it, then put in standby when I don't, and shut down at the end of the day.

When it needs rebooting. Other than that, it stays on from 8-9 in the morning till 12 - 2 am the next morning sometimes. Then I turn it off.

I turn it off if I'm going out for the day, and I also turn it off each night before I go to bed (unless I'm running a full AV scan as that can take hours and doesn't like me doing other things at the same time). Only other time would be if a programme asked me to restart it after an update. My father leaves his on 24/7 - he says that is better for the computer than what I do. I've never asked a professional if he is right though - so if anyone in this forum has thoughts about that I'd be interested to hear them.

My experience is that the ones that stay on all the time generally last longer than the on/off ones.

Of course it depends on the operating environment and a lot of other factors, but I suspect that the thermal expansion & contraction of all those soldered joints twice a day will take their toll over time.

Constant temp = happy components. :)

My work PC gets rebooted every couple of weeks or so - basically whenever required by Windows Update. It's on standby overnight, starting a few hours after I leave work, as there's a background backup job running an hour or so after I usually leave.

Last time it actually crashed? - dunno, but definitely last year sometime.

Once usually when it gets turned off. Sometimes I turn it off before that but then there's always some reason I need it and have to turn it back on so mostly it's on all day.

Thank-you fred_fish :) Hmm. I might have to change what I'm doing then. I thought it would wear the parts out more quickly being on all the time, but what you say makes good sense.

It's a laptop kept on a wooden desk - it wouldn't overheat being on all the time? Would going into sleep mode when not in use keep it warm (enough)?

Same for me, it usually stays on for weeks. And I don't pay for power at my apartment. :D

Windows Updates are annoying though. Thought I turned the damn things off but then I come home and find it's rebooted itself.

Windows 7 - Asus notebook. Doesn't crash. Only gets turned off (briefly) when a Windows update requires it. Otherwise it's on 24/7.

I have the screen turn off after 30 minutes of non-use - but that's more to save the screen than electricity - it's LED backlit anyway, so uses b-all power...

Electronic components have finite life in 1000's of hours, as do HDDs etc. You can use that life up in 3.5 years or 10 years depending on how soon a worst case scenario looms on your horizon so that the computer can sense this and die at the worst possible time.

Not only that, long term heating is the enemy of all electronics and thermal expansion/contraction is a very minor factor in modern electronics

I turn on my computer when I'm ready to begin work each day, and turn it off every night. Not only does this extend the working life expectancy, it also gives me a clean boot to start every day. Proof of the value of minimising the hours lies in the performance of my last two computers. My immediate past box has done 9 years and only just had a major problem. It had only one OS reinstall in that time too, caused by a mistake I made, not any need.

The computer before that I called 'Old Faithful' because it started with Win95, moved to Win98 and ran way past 12 years service, ending its days as a print and mail server. Off every night, on every morning, mostly 7 days a week and I think it only died last year.

I just hibernate it at night, standby when I'm away during the day, and restart it when it needs restarting, around once a week.

@ BillyT
Fair enough, that is another pov.
I haven't done any scientific studies or kept statistics or analysed it in detail, it's just my feeling based on my own experience.

I too, have long lived PC's, my current router began life running Win95 and has been ON since 1997 :)
I have an '02 vintage machine that is now a mail/file/web server and has always been ON.

I've heard the arguments for and against, some have merit, some not.

I've supported machines in quite a few engineering/automotive businesses over the years (with offices that get cold overnight) and noticed a difference in longevity between the pc's that stay on and those that are turned off each night.

Leaving them on WILL cost you more for power. If you are only using it a few hours a day, turn it off.
PC's can, and do, fail, at any time, for any reason (cosmic rays have a lot to answer for too :)) wheather you run them 24/7 or turn them off.

You have used the same router for 13 years? Thats impressive if its not a typo.

Personally my desktop is on most the time, only gets turned off if im at the mrs place for a few days, and lappy only gets slept when its travelling but otherwise its on 24/7

I've had it longer than my children :cool:
486DX-2 16MB ram 120MB HDD
I got it when it retired from about 3 years service at Westpac IIRC :)
Converted it to my dial-up router, web, ftp, mail server & PDC.
I offloaded most of the servers to the other machine a few years ago, but it is still happily chugging along, now routing my 10Mbit cable connection to the rest of the LAN.

One little computer current up time is 4351 hrs since last reboot, that was when we had a prolonged power outage and the UPS ran out of steam. (Naturally, this has no MS products on it.) Others run as required, usually get turned on and stay on until time for my bed. I would prefer to leave them all running 24/7 to minimise cyclic heat stress but the heat, noise and power consumption of that scheme are against the theory in practise.

National Semiconductor (I think) a few years ago put out a failure analysis that broadly said contamination of the die caused most problems involving chip failure. The contamination arises from thermal cycling stressing the metal-to-resin package boundaries causing mechanical bond failure. Thermal cycling (again) causes ingress of contaminant-laden moisture which does miscellaneous nasty deeds to the chip surface and leads.

The recommendation was to minimise the number and range of the thermal cycles by avoiding unnecessary shut-downs and ensuring good ventilation with clean air. Cleaning of the circuit boards was mentioned as a "good thing" provided that static charges were dealt to appropriately since static damage during service is another large cause of failures. Perhaps we should be grateful for a humid climate that helps mitigate damage caused when we get lax with anti-static precautions, but high humidity brings the moisture in that does the damage on the cool part of the cycle. Passive components have different rules, capacitors and resistors tend to be life limited mainly in running time and electrical stress levels. For everything, hotter is worse, much worse. The whole shebang is a plot to mean "Do whatever you like, it will be wrong".
Fortunately for reliability, we have got rid of valves, high voltage, mud resistors and paper capacitors along with germanium transistors (which were only just better than valves).

Judging from network uptime... 7 days 21 hours. And that only means I haven't taken my laptop out for over a week. I'm sure it's been running longer.

I never turn mine off, except when I have to reboot to clear out the ram etc, perhaps once a week on XP.

Also I have my pc in a little room and find that leaving it on helps to keep the room a bit warmer in the mornings. (econo-heater ?) 350W PS ?

Don't knock old technology, it will still be operating when today's state of the ark is dead and buried.

I have valves here that are up to 90 years old and still in good working condition. I have 70+ year old radios that still run well.

Moving forward in time to the more recent past, I have 50 year old transistor radios still in good working condition, and they have never been serviced, just put in fresh batteries and away they go. They are full of those dreadful germanium transistors too, and I have some of the very early 'production' mid-1950's germanium transistors (NOS) that test just fine.

Bakelite was one of the first plastics, if not THE first plastic, and it doesn't decay after a few years in the sun; you can bury it for decades, dig it up, clean and polish it and it will be as good as new. Don't leave modern plastics in the sun, they can't take it.

None of this old stuff is anything special, the only unusual thing about these items is that they got put somewhere and forgotten for a decade or several, then reappeared when the old homestead was cleared out or some similar domestic archaeological expedition uncovered them.

It would be interesting to review today's technology in the year 2060 or 2100 and see how much is still working.

Forgot to mention the server :blush:

The server, running XP, is automatically shut down at 10pm each day and starts up again at 7am. The only reason it shuts down is to save power: if power wasn't an issue then I'd leave it on all the time.

Laptop never gets turned off, probably rebooted once a week. Last week I gave it it's yearly dust clean out as it was starting to run a bit warm, amazing how much dust accumulates in the HS fins over a year.

Grunter desktop only gets turned on when it's needed, which is probably 4 hours a day.

Windows updates can occasionally frustrate me, no I don't want to reboot now or in 4 hours. net stop wuauserv is very useful... :p

A few times a day.

Recently I been doing some power bills investigation.

Not done the PC yet. But our CRT TV and Sky uses 0.2kW for the hour minus everything else. Bit surprised thou.

Everything else means, you wake up before everyone else take a meter reading and go back 15mins and retake it, convert this to the 1hr.

Recently only been using my computer when required, that might mean 1hr before bed time. Helps with my 3GB internet cap too.

My desktop goes on around 6pm when I get home from work and off at about 11:00 when I go to bed.

When I had a server (now don't have room for it :() it stayed on 24/7.

Greven
21-04-2010, 10:56 PM
I reboot when an update or something wants to reboot. Other than that, I just let it go to sleep.

I know shutting it down uses less power, but sleep mode uses hardly any power anyway & resuming from sleep is much faster than a cold boot.

I've installed Windows ME on only two computers.

First one it would have random problems, crashed a few times but after installing all updates from Windows update it ran fine.

Second time, It was crashing so much I couldn't get the updates installed. It corrupted its own registry or something, couldn't recover it (because it crashed while trying to do that too) and then refused to install the updates because it thought there weren't any.

Symptoms you would think were classic signs of hardware failure, but no. Went back to Windows 98SE, stable as a rock.


I always thought people were joking about how bad it was, but only had to try it twice and I was amazed really at how bad it was.

It's like Microsoft shipped an alpha version or something...

Is it true that if you restart your PC several times per day, you will damage the components within the PC?

I don't think it's likely, not with modern components.

Agent_24
22-04-2010, 09:35 PM
Depends what you mean by restart. If you do a soft restart by telling windows to "restart" the system stays running the whole way through.

If you shut it off and then turn back on you will be reducing the life of some components eg: hard drive by increasing the spinup count, head load count etc or PSU with high inrush current at start (although if that shortens life is a matter of debate)

But then to leave them powered on will decrease life anyway as they are staying on, really it's probably the same either way
