How to Detect fake knockoff counterfeit IBM AC Adapter form genuine Power Supply

[justanotherphoto]

If the ac adapter works one day and then the next day it failed to charge the main lithium ion battery, then that means that the current source of the ac adapter is inconsistent in it's Voltage output. Your DVM meter will be constant, but the current ampere is what varies. Therefore ntermittentency has to do with the power transistors used in the design, which in most cases when engineering reliability issues exits and are overstressed by thermal runaway, devices become unstable.

Yeah.. I bought a fake ac adapter for my dell latitude on ebay for 10 bucks, and all it does is power on my laptop, but it doesn't charge the battery. If I'm lucky in some days and wait patiently, it will sometime charge. LOl.. Sucks, but it saved me from losing all my work, and I'm thinking about purchasing another one but this time it has to be genuine.

I bet it weighs light and gets hot too. They have the real Dell Pa-6, Pa-10, Pa-12, etc. at GetAdapters site. JR
