ok without power on, put your right forearm against the small screws on the right side of your macbook... big deal right...?

now, take your arm off, and plug the power in.. now do the same as above... do you feel a small electric current? it is bloddy annoying (i have a may macbook white)... i hope this is not a power afult...

although it could be bcause your on a pro

no i was using my girlfriends powerbook, im still waiting for my mbp to be delivered. should reflect that in my sig really.

Happens because the Powerbook and MacBook Pro's case are aluminium, therefore capable of possessing a static charge.

I find that I get a static shock if I don't use the extended cable with the power brick - since the extended cable has an earth wire.

Well, it does in the UK - we think about safety with our plugs you see

Hmm, my power brick uses the 3-pin plug thingy but I still get shocks while using my MBP. Its most noticeable on top of the keyboard that small strip of an area right in front of the wireless antennae. Whenever I run my fingers lightly along it you can feel as if there's some friction/resistance from it (hard to explain). Is it inherent to all MBP's?

Although its using a 3 pin - the earth pin isn't actually connected to the power brick.

Examine the 3 pin plug that connects to the brick - you'll see why.

 

[deanops]

yes, all valid points, however:

i am talking about a macbook (sans the pro)
and also i am using an earthed extended cable...

 

[Cybergypsy]

Had mine 2 days yes I have the same issue as you crap thought i was the only one...... not all the time only once a day so far....

 

[Igantius]

Tried it - nothing happened.

I have this problem on my MBP. I notice it the most when i am in my basement which has a cement floor. If I pick my feet (bare) off the ground it stops. Must be some sort of electric current.

I think I have a last May (2006) MacBook and I'm not getting anything.

It is a weird feeling though. I would get that when messing around the back of my PC. The only thing going through my mind was if all this electricity was messing up my computer with over $1k worth of stuff inside.

I'd call up Apple and ask them about it.

Examine the 3 pin plug that connects to the brick - you'll see why.

There are hidden metal contacts on the 3-prong connector which mate with the large metal pin on the power brick. That's where the earth connection is. Look closely and you'll see it.

Yes!!! I've had the same electric shock problem when I touch the screw on the left hand side of the trackpad!!
It freaked me out the first time, I thought there was an electric leak, but I've just learned to live with it.... really quite annoying though, especially when you're holding the MB on your lap.
