[Ham-Computers] Laptop batteries

Aaron said, "...My take...what a great example of poor engineering!  Don't get me wrong, Apple laptops are nice, but I would think that any computer's power supply should be designed to fulfill the max power demand + 20% overhead..."

I couldn't agree more!

Does anyone know what engineering justification could possibly exist for "underengineering" a device's power supply, to the extent that at full load efficiency is decreased because the switching power supply is overloaded and must be supplemented from the battery?

How about safety?  Are we talking about a fire that's about to happen?
