Fake Chinese Power Supplies on Market Causing Power Consumption Problems
Hi Guys, Letting you know.
There has been a growing problem with cheap and fake supplies coming out of China, which can cause excess energy consumption and potentially even safety problems.
EU regulations (known as EuP) state that a computer in off mode sold after 2010 should consume less than 1.7W in standby/OFF mode (with wake on LAN enabled).
Although this is hard to measure, a cheap power meter should provide you with an idea if the computer is 'out of the ball park'

One big issue has been with unsafe 'universal' or 'replacement' Laptop power bricks, if you have a power brick, check that it states the manufacturer, model number and bears the CE mark. Many of these fakes just display CE, voiding the 'manufacturer' of any responsibility. Check the brick has some weight to it, the cheap fakes feel really light.
Often these fake parts also contain materials banned from import into the EU for safety reasons under the RoHS directive.
