Yes this is true, and almost true about everything with wires/mechanical stuff (Devices, engines etc....), for the most part you get these warnings, but the standard thing that people do is to ignore them as a glitch and then boom baby, your device fails...

So i would say the same as geneven, check it out to be sure, don't have to get you soldering iron, just open it up and preferentially look it over with a magnifying glass.
