…are to which I devoted a couple of years of my work life. To see what the standards are about, trace the power line of your laptop. A bulky, square block, AC-DC converter, sits in the middle – which converts the raw AC electric line into a smooth, lowered and tampered DC power line for the fragile laptop components. In the back of the converter block we see several icons and instructions – all explaining with courtesy what a electrically dangerous environment we live in, and how they assure the dangers are eliminated.
According to my experience, these standards do help making the device safer:

• Make sure that the wires do not touch a sharp metal.
• Make sure you use only certified components (hopefully from us) for power-related circuits.
• Make sure that the device does not explode after being exposed under extraordinary heat for several hours

But we all know that when things go worse, it does. The news might even get amplified and hurt the business. But the "safety standard" compliancy was never discussed.
Previously, I thought the importance of these little "safety standard" signs were undervalued. Now it looks like they are getting irrelevant.
I still support some kind of safety rules, but that battery incident showed that the current scheme is not doing enough (at least for us). Otherwise those little icons are there for no purpose. So were my two years.
