A little story for you:

Once upon a time, there was a UK off-road vehicle manufacturing company called Land Rover. This company made several styles of off-road vehicle, from the basic, stripped down and rugged Defender all the way up to the full-featured and comfortable Range Rover. In between these two was a comfortable yet capable off-road vehicle called the Discovery. Discovery was fitted with a device called ARC, the acronym for Anti-Roll Control. This system allows the suspension to dynamically adjust the resistance in each shock absorber, preventing the very heavy body of the vehicle from rolling in the corners.

Unfortunately, some mean old Lawyers came to ruin their fun. "ARC" needed to be renamed! " People will believe anything," the lawyer says "and we mustn't tell them something which they believe is true, and could hurt us if it isn't. Anti-Roll Control implies that the car will not roll, and therefore cannot ever flip over."

So, with the lawyer earning his £3489057495 a minute salary, ARC and all its impressively named glory became ACE, Active Cornering Enhancement. All because "When you make something idiot proof, they'll find a better idiot."

I hope none of these batteries ever explodes.

So no smoke, just shrapnel, then?

I for one will miss our exploding laptop overlords.

I love the idea of a load of Brummie engineers sitting around, trying to think of a new name for the system, before somebody asks "Why not just call it 'Ace'?"

Pardon my ignorance, but I don't recognize the acronym. 'Urethane varnish' is the best possibility I can come up with, and that's a rather strange thing to put on a computer case.
