Here's a good one for you, my wife noticed today that if she lightly touches the area to the left of the trackpad on her revA 12" powerbook, she gets static shocks. I tested it and it's true, BUT ONLY when the power supply is plugged in.
I tried this on my Tibook and I get it too, but less strongly than on hers (I had to use my lip to feel it, and yes I looked stupid, but it's definitely there)
Anyone else ever get this, or can suggest why it happens. Again it only happens when the power is plugged in.
Cheers,
J.

The newer power supplies come with a grounded cord and a two-prong foldaway plug. You can tell which adapter you have because the ones capable of grounding have a metal stud (instead of plastic) to hold whichever of the above you are using in place.
Are you using the grounded cord or the ungrounded foldout plug? What happens if you switch them?

Yes, I've felt that, too. It's more of an electric shock, not a static shock.
I wouldn't worry about it. The external power brick should isolate the PowerBook from high voltages.

Ah! That will explain it. I just moved from the US to Borneo, and am using an ungrounded adapter lead plugged into the power supply, as is my wife. I'll cut the plug off the grounded lead and put a 3 pin plug on it and try it, but it sounds as though you've identified the problem.
Many thanks,
J.

yeah static shock and electrical current running through your powerbook are two different things. The PB's not grounded (as already pointed out), so um yeah.

When I first started using my Powerbook on these two tables I have, both with a glass surface, I was getting statics throughout my fingers and up my arms. But it disappeared or dissipated after a shirt time. Maybe I still get it...let me check my hair in the mirror.

I received what I thought at the time was either static sparks or a slight electric current through the powerbook case. I noticed later that the areas the case had touched became blistery and sore - it turned out that I had received internal radio frequency burns from a botched repair job. They had left the airport antenna wire in a position that it was contacting the case and thus me.
