Dead Switch Mode

Hi Andy,

I have no specific technical expertise nor any have I yet found any more information on the phenomenon to which you refer.

I have however, had 3 such similar incidents with defunct SMPS, units in question had been powering various computer peripherals and in a major re-organisation, a number were turned off whilst functioning happily, repositioned and refused to come back to life after having been turned off, no amount of leaving them for a period to cool or reset made any difference and all 3 had to be replaced, most aggravating.

I too have become rather suspicious of them following those incidents.

Another one bites the dust, less than 2 years old, powering my gigabit switch one minute, network down the next.

Put the DMM on the output, down to 2.1 volts instead of the 5 it should be.

More crap foisted on us in the name of environmental protection to go along with "gloom bulbs" and aerosols that deposit flyspray on anything within 5 feet due to inadequate propellants with the phase out of CFC's.

Now our brilliant politicians are off to sell off the electricity generation stations before they have to spend up on environmental controls, after raising prices 35% in the last 2 years and selling off virtually all major road infrastructure to toll road operators.

Nothing much seems to have changed here since the days of the "Rum Corps".
