Grounded plug for dell 700m

Hi all-

I have a Dell 700m that I just got a new power brick for, which has, gasp, a 3 prong plug. I am trying to wrap my head around this - why? Its a laptop - as portable, it will always have a floating ground! Seems silly in my opinion.

One of the reasons I ask - I have an APC universal power adapter that is a 2 prong adapter. Now, it does plug into most dells, but not this on, so I have to fashion a new plug for it. I have the 3 cables, plus, minus, ground - to throw on to a 2 prong, plus and minus. The simple solution is to just ditch the ground, rather as if I had the original dell power brick and put a no ground plug asapter on the back. Its a laptop, for crying out loud, I do not think it should matter...

However, I would like to get opinions prior to starting my little experiment.

Thanks all

Eric

My eMachine came with a 3 pronger and it is a pain in the ass if you try to connect the laptop to most proffessional (grounded) Audio or Video gear. The third (grounding) prong is not connected to the laptop chassis ground, so can you say 'Ground Loop'... I agree that it is pointless, but left mine intact and resort to an Audio Isolation Transformer, when needed.

I consider myself a musician- well, who I am I kidding, I play the drums. They dont plug in so most of what you just said just flew over my head.

I am just going to not wire the ground in, see what happens I guess. The APC unit hasnt a grounding plug, and my Asus W1 does, but it charges fine off the non grounded. Were dealing with laptops here... a floating ground isnt all that inconcievable, seeing as thats what they do...
