RE: WATCHA DUIN TODAY. - 15

Good Morning Signman,

If I went out that early I would need a couple of naps too.
VM

Morning all...........Jim has lost his mobile.Great start to the day.

Was doing some volunteer gardening and they were having a photo shoot..........this model has just won Britain's next top model.She is welsh and she was lovely.

Well the weather has been fab today,really enjoyed it.

Denise

Sorry she doesn't look all that fantastic to me, there again I'm not a glamour model fan or a fashion one either. I always think you can see better looking girls on the streets of Birmingham any day of the week.

Phil

Well I don't think my pics do her justice really Phil.

Denise

Perhaps that is so, but what I said goes for all these top models you see getting treated like they were queens or something special. Give me the chance and I could walk around Birmingham for an hour and come back with photos of far prettier girls.

Phil

Very true Phil but as we all know beauty is in the eye of the beholder.

Morning all,
Taking the hire car back 8 am, then uploading my photos, and start another gallery BIRMINGHAM A different view.
Messing about with a laptop my daughter gave me, it will only switch on when the lead is underneath with the laptop resting on top of the lead, I suspect a dodgy soldered joint or connection, VM may think otherwise ( what do you reckon Dave.
Got to go food shopping the cupboard is bare, looks like another very hot day here, all though I had plenty of those in Overbury.
Have a nice day ya'll.

Good Morning Signman,

If the laptop works when on battery only, then it is the PSU that is at fault and It is most likely a break where the PSU cable goes into the DC plug, bending it over and holding it in place with the weight of the laptop is keeping the break closed.
If you have another suitable PSU it is easily proven.

What's a psu ?

What's a psu ?

Morning Dave,
I've opened it up and there is definately a bad joint where the psu connection joins the motherboard, so I will just leave it, as I only use it as a second machine and never take it out,it seems fine and now I've just added another 256MB of memory it's going great.
SB psu =power supply unit.

Good Morning everybody,cloudy here today so hot yesterday feel dissapointed.Let us hope it warms up.

Thanks VM I knew it wouldn't just be called a Transformer. That would be too easy.
Now you are going to tell that isn't all it does arn't you. SB

SB, I didn't say anything, that was Signman.

Anyway it isn't a transformer as such. For most electronic equipment it is a Switch Mode Power Supply.
It takes mains voltage (96-260v ish) and switches it at high frequency, using transistors, into a wound inductor type device (transformer) where the voltage is isolated from the supply and changed into one or more values then rectified and smoothed and taken out to the equipment to be powered. This output is also fed back into the controller circuit responsible for the whole operation so as to regulate the output regardless of the input voltage, usually via opto isolators to prevent direct connection between input and output. The most comman source of failure is the capacitors drying out due to the high temperatures they are running at, caused by the high frequency of the switching circuit (oscillator).

Of course I may be wrong.
