Anyone else get a little shock from the metal pieces on the bottom the the G4 iBooks? I am talking about the screws, the metal things around the feet, and the battery latch. It only happens when the iBook is plugged in and if my skin is slightly damp.

No. Are you on carpet when it happens? Do you otherwise have any noticeable static electricity in the air?

Depending on what you mean by "damp," this might send a red flag my way if it happened to my iBook G4.

I went for a run, came back, went to check my email and put my laptop on my legs that were a little sweaty: ZAP.... not really a zap just a small buzz and I took it off my legs. Touched the center screw, same thing, then the circle thing around the foot.. ditto. I can touch it now with my fingers and I don't get anything.
It wasn't static because it was a flow of current but yes I was on carpet.

Yeah, I'd say that's something that it's not supposed to do. I'd get it checked out.

Yes i also experience it 2 on my current iBook G4 and on the iBook G3. Its always when its connected to the adapter. I always get it from the latch mechanism.

I think the iBooks EMI schield is under current when its connected to the Adapter, because the Latch mechanism is connected to the EMI schields.

Well its ok i dont mind

Big question: are you using the 3-pin adapter or the 2-pin adapter? Does it change when you switch?

Also wondering if you are using the three prong adapter. If you are using the three prong adapter for the charger, that should ground everything properly and you shouldn't be getting a shock. But you shouldn't be getting a shock anyways. I'd send it back.

... unless your wall jack isn't properly grounded.

I've never felt a shock even touching the plug... one thing that comes to mind is that the line from the inverter to the display may be stripped. It outputs AC and therefore would be far easier to feel than a DC current.
