Switch off & unplug

gromituk

Interesting - can you point me at an example of one that doesn't, please?

And I'd also be interested for you to tell me what proportion of mobile phone chargers behave in this way.

Oh look - deafening silence. :rolleyes:

The advice to swich off and unplug came after a series of fires in the 1970`s which resulted in multiple deaths. They occurred when the push button of TV`s overheated, even though switched off at the set. The switches are more reliable in newer sets and, if you have newer wiring and fuse boxes in your home, there should not be such a problem. But, if in doubt, unplug the appliance.

No, someone with a life.

Most modern phones are supplied with switched mode power supplies, not conventional transformer power supplies (they are the ones that are very light weight). When there is no load (i.e. they are not charging a phone), then they effectively draw no electricity, unlike a conventional transformer power supply which does. Hence why a conventional transformer power supply remains warm to the touch when switched on and not connected to a phone, but a switched mode power supply is not.

All the figures for electricity use of phone chargers is based on conventional transformer power supplies.

Is that enough detail for you.

Really? You seemed to have plenty of time to make other postings yesterday. :rolleyes:

Whizz - there go the goalposts. Suddenly, the word "effectively" has appeared. They either draw power or they don't. Which one is it?

Just in case you've forgotton:

Yes - It's taught me nothing about power supplies, but very elegantly shown what a fool you are making of yourself.:T

I doubt anybody could teach you anything.

does it save energy if i log off on my pc rather than turn it off every nite

Turning your PC off at the wall, or shutting it down, will save energy. Leaving it switched on will not.

Still a bit confused ........ sorry..........

I have a socket which I can't easily get to, so it has a four socket extention lead in it.

If nothing is plugged into the 4 sockets is any power being used?

If something is plugged into one of the sockets but is switched off, eg a radio, is any power being used?

Just trying to be absolutely clear

Thanks

What about the video? This is my biggest problem as I get fed up having to reset the time everytime I turn it back on.

So don't set it then. My tv, digibox, video and dvd are all on an ext lead, when I'm not watching I switch the ext lead off at the wall, my dvd automatically sets itself when switched on but video doesn't so I leave it, I've got a clock on the wall anyway. The only prob is when you want to record, so I'd say just set it then. People seem to make such a big deal of energy saving and the like but it's only a hassel if you let it be, chill!
