I'm talking about very frequent ignition during a day

Each ignition of a PC or any device causes a voltage spike in it. And this reduces the life of the semiconductors present in any electronic device.

For a day, it is better to put the PC on standby several times, rather than turning it off, in addition, it comes out of standby more quickly than a full ignition.

Ah la la ... More "we say" that make law! : Evil:
I turned on my PC on average 3 times a day for 8 years, that is to say close to 9000 switching on and off. He never complained and still works!
I do the same with all my devices (PC, TV & co).
Explain to me why I never had any problems!

We have to stop looking for phony excuses so as not to save energy. :P

(yes, I'm pissed off)

What he says is true, they are not "we say", when you turn on a device you always have a voltage peak at ignition. Now it's not because you never had a problem with ton pc in 8 years that it will have no effect on other devices or other people's computers.

Now an 8 year old pc is already a little more resistant than those of today. You know that Intel stopped producing Pentium 1 just two or three years ago. Because it was always used in space shuttles because they were much more resistant than newer processors (and of course because they do not need more powerful for the applications concerned).

I do not dispute the voltage spike, I dispute the fact that it causes the components to burn out.

I have the same behavior with my "pro" PC (Centrino) which is 2 years old: I turn it off as soon as I take a break when I go to lunch, when I go to a meeting (I turn it back on in the meeting room) , etc ... (for info on the startup delay, I put it in _prolong_ standby: all the memory is stored on hard disk, then the power is cut)
No worries either.

Ditto with the TV, radio, internet box, incandescent or fluorescent bulbs & everything we can have plugged into the mains and which is not useful all day long, and yet, I never had any problems

: Idea: I do not believe that my TV, radio or other have already gone into orbit, but maybe I am wrong ...

I'll even tell you that those I hear saying that you have to leave everything on all day change their PC every 2 years max on the pretext that it is not fast enough ... It is therefore not a problem of longevity of equipment, but a problem of laziness.

You never have anything that breaks down at home, not even a bulb that burns out, it's good you have a great chance, play lotto : Mrgreen:

Otherwise I don't have any problems in general with my devices that I turn off every day, now when you have something that breaks down anyway you will not be able to define if it is the ignitions and these peaks tension which made it break down but it must surely play on certain breakdowns it is clear. Anyway my PCs I don't keep them long enough for them to break down : Mrgreen:

I keep my things much longer than the average person.
On the fluorescent lamp side, I only burnt one: I bought it from my parents in the late 80s (I only remember the fact that they were the 1st and that my parents weren't hot to buy "that"). I took it home in 1997. It burned down ~ 2 years ago. Like what, turning it on / off often did not hurt it too much: about 20 years of life!

It is undeniable. On the other hand, I can compare the longevity of my devices to that of people who turn off their devices only once a day (or not at all) and I can tell you that I have nothing to complain about, quite the contrary.

That’s what I’m saying. So why not turn them off several times a day? You'll see if they cry before you have time to change them.

I did not say that switching on and off a device every day _considerably_ its lifespan and that it had to be changed every year.

I also turn off my PC every day, my TV and company ... Even my 8 year old PC I still use it.

My job was just to say that switching on / off shortens the life of a semiconductor, but given that they are changed before their end of life, in general, there is no time to see them burn because of that!

in short, all that to say that those who say that the ignition / extinction damages the material have a reason to say it.

Here it was just to inform.

Still, I remain of your opinion: switching off a device that is useless is better than leaving it on since it will probably be changed before its end of life, or will have secondary functions by then

You didn't understand me: I'm going further than that!
I tell you that you can turn off your devices several trouble-free once a day (not just once a day)
