Hello,

I just bought a MacBook today and so far I love it. Until my Booq Vyper comes in I slipped it into the notebook sleeve of my backpack. When I pulled it out of the bag at the library I got a static shock. Is this a common problem with this kind of finish/material. Could I have hurt anything?

The other thing I noticed is that while charging and running, there is a high-pitched hiss/squeal coming from the corner of the laptop near the power cable. Removing the cable makes the noise stop. It's not very loud but it is audible sitting in front of it. The noise changes depending on computer activity, but is constant at idle. Is this normal?

nah doesnt sound normal to me, id take it back or to your nearest apple shop and get it looked at!

I dropped it off at my school's store, they are going to look at it. I'm going to see if my friend's macbook squeals when charging as well.

Checked out my friend's notebook and it does the same thing! Tricks like opening Photobooth to stop the noise worked on his as well. It appears to be a characteristic as well as a defect (imo). It's not terrible and otherwise the laptop works perfectly, so I suppose i'll just have to get used to it.

Interesting. I'm referring to when the battery is being charged by the adapter and when the computer is running. Put your ear close to the upper left corner. It seems to be a common problem. I'm guessing you are just not as sensitive to it. Or heck maybe you are lucky enough not to have it at all. But I would be suprised. Oh, did you do the latest firmware update?

A thread you linked to on the Apple Discussions say it's the CPU. Mine has a small squealing sound but only when I place my ear towards the left side. No big problem...when is my head going to be that close anyways?

10-02-2007, 05:50 PM

yeah, it is definitely the cpu. My beef was that I could hear it when it sits next to my other monitor on a stand on my desk. I guess I need to deafen myself a bit until they release firmware or something.

Just put my head up to the left corner, I can't seem to hear anything.

That static shock is what's making me think you have a defective unit. The thing is made of plastic, you shouldn't be getting shocked.

I get the high pitched whine when mine is charging, but it's only really noticeable in a very quiet room and my ears are very sensitive to high pitch sounds.

Thank you for the posts guys. The authorized Mac guy at school said the noise is typical and not to worry about it. I've already gotten used to it for the most part. The only time I really hear it is my quiet dorm room. I don't think the laptop is defective, everything runs and works very well. As for the shock, it was a static shock of the case, not an electrical shock. It was from all the friction sliding it out of cheapo polyester north face sleeve. (probably like the static you can generate from rubbing a balloon on your head) It doesn't seem to have done any damage since the quiet hiss seems very common.

Thank you again for your input and posts.

Mine squeals and I think I made a thread about it also when my laptop was new. I promise you, in a few months you'll be saying, "what squeal?" because once you stop thinking it means there's something wrong, you won't be listening for it and you won't hear it either.

I wouldn't worry about the static shock too much. It is a shiny surface, but if it keeps happening then maybe pop into an Apple store and mention it and see what they say.

a couple things can cause static shock. perhaps it was the carpet in the library and the touch of plastic (your macbook) that elicited this response. in anycase it's no biggie and should be nothing to worry about.. but..

A SQUEAL?!

doesn't sound very normal to me.. i'm really hoping that you're mistakening it for the fans because a squeal should be taken care of, STAT!!

I haven't had the problem with the squeal either.
