OS X :: Electric Shock / Vibration On UMBP 5?
Nov 3, 2009
I took the plunge and got a MBP 13 (5,5) in October. Its all going well except for the same problem that recurs.
The problem is that when plugged in via magsafe i recieve a mild tingling throughout the shell. This first happened a week after I got it but I solved it by using the long lead instead of the smaller plug. But now even the longer lead which is supposed to remove the issue still gives me the same vibration/electric shock feeling. Its NOT minor, I feel it when its plugged in and it hurts! I get a headache when it does this.

My mouse wire (or cable, or whatever..) is kind of messed up with the wire showing on the connection to the mouse and basically in the middle of the wire towards the USB connection to the CPU. It's the Apple mouse.. will I get an electric shock if I touch it while it's on? It's kind of sounds funny that I'd touch it but you know ..
I have electrical tape I don't know if that's necessary.

I don't know if this is something to be worried about but I notice that when the tip of the display port cord ( from the ACD ) touches the metal frame of my MacBook Pro there is a tiny blue arch of electricity visible. Well, I just bumped that cord into the frame of the MBP and as soon as that happened the computer completely shut off, it just went to a black screen and turned back on when I connected it via AC outlet. When the computer started back up the clock was messed up ( 2008 date ) and it had forgotten all of my WIFI passwords.
I was just wondering why this happens?

I am contemplating upgrading my stock 250GB drive in my 13" uMBP(June 2009) with a 320GB 7200rpm WD Scorpio Black:
[URL]
I was reading and some users have experienced unbearable vibration and increased noise, while some have not. I would live to be able to increase my HD speed, and am too poor for an SSD at the moment.
What are some experiences people have had with putting a 7200rpm in a 13" uMBP and would you recommend the upgrade?

I know it might be nothing, but just thought I'd make sure. I've been using an Aluminum Macbook for a few months, and it's been working super great, well, until yesterday, I'm not even sure if it's been this way the whole time, but it's been driving me nuts since this morning. The problem is, I've been feeling a little vibration around the entire trackpad area, especially on the right side, it's probably coming from the HDD (Factory drive 160GB), but I really don't like it. It's nothing noticeable, I mean you can't tell the difference until I've told you about it or unless you've been resting your hands on it for a while, but the point is, it does exist. Now my question is- is it normal? Was it there the whole time? If it's not normal, should I be taking it to the store? I've never even opened up the bottom, ever, it's been as it was on day 1. I tried listening to it carefully while giving it a little shake but nothing seem to out of place in there, it still feels as solid as new, but the bottom line is, I'm going crazy. What should I do?
P.S. It's got nothing to do with electricity cuz the vibration remains when I run it on battery.

During winter months up north, things get cold and dry quickly. As a result, static electricity discharge becomes more frequent. I've always had a minor issue with my various Macbook Pro's over the years. But with my new MBA and the sudden drop in temps here in Chicago, my MBA is off the charts. I have started my winter routine of touching something else to discharge first before touching my MBA. Otherwise, I'll arc a spark every single time.

Twice this week I?ve been shocked by Static electricity as I touch my MacBook Pro. It?s cold so I get shocked a lot lately. Is the MacBook Pros internal circuits safe from static shock? Is the outer shell protecting the CPU?

So I'm at a client tooling around with my late 2008 Aluminum MacBook. Carpet. Cold, dry weather. Are you getting scared yet? Go to pick it up off a table and zt! Shocked the hell outa myself and apparently my MacBook. I grabbed it on the right hand side and the static charge must have discharged through the slot loading cd rom drive. Now it won't charge. Battery and Mag Safe brick tested fine at the Apple store. They're going to swap out the Mag Safe port for $110 first and then the flat rate repair for around $380 if needed. Note to all Aluminum MacBook/Pro owners. Ground yourself, or plug in the grounded PSU brick.

When the Macbook Pro is charging, I can feel a little electricity in my fingertips. Unfotunately, I don't have a three prong outlet, just two. Either way, I think this was not supposed to be.

I noticed that the MBA only has one headphone jack.
Now is that both input and output? If its not input then i would need one of those fast track things im guessing.
I have both input and output on my hackintosh which I can use to record my electric guitar on GarageBand.
I hope I don't have to buy a fast track as not sure how it would run over a USB hub.

The screen saver that this produces are beautiful but is it safe? It works via your computer communicating with hundreds of computers around the world?

I was an owner of a white macbook for just over a year until the motherboard decided to give up the ghost... So I eventually bought myself a new 13" Macbook Pro. Everything was going just beautifully, until I realised when I was charging it, I had this weird electrical current going through all the aluminum.First of all the first two things that came to mind was. What's the computer and most importantly MY health going to be like if its exposed to all this! Anyway. I read a few threads, and they were talking about the "Grounding" problem. Luckily I got my old macbook charger out and plugged it in.. The problem went! So I was then thinking on where in the charger lied the problem? So I took the cable part from the Megasafe to the socket from my macbook, and then put it into my macbook pro Megasafe... and everything worked brilliantly! I'm no genius, however if you guys feel that tingly electrical/static current going through you're MBP, go and buy yourself a new cable. However as Apple is so popular, I'm sure if you try one of you're friends (As they will undoubtably have one) and see if it is that the problem. In anycase, I'm very happy with my Macbook Pro Apple make some awesome products. Bill Gates should just pack up and go fishing if you ask me. He can never compete with Me old mate Steve

I've linked my guitar up to GarageBand and am trying to get a setting which sounds metal like, but at the same time sounds clear and i'm failing. It produces a good sound but its so full of noise its unbelievable.
The guitar has no noise when its on a setting which doesn't have distortion/fuzz or gain on it, but then i don't have a metal sound.
Does anyone have any idea how i can make such a setting?

Picked this up from the Apple Store in London a few day ago and I've been having some trouble getting my electric guitar to work with my mbp.
When I plug everything up and try and play it records through the mic on the mbp and not through the pickups.
In system pref>sound>input I have line out selected along with the volume all they way to the write.
What am I missing here?

first time post here and a noob question. I've had my MBP 2.4 i5 since early June and I noted a noticeable vibration. I'm not quite sure if it's the fan working or the HDD spinning. istat shows my fan running at 2000 on average both left and right, GPU and CPU temp around 38 on normal operation such as browsing on safari. The reason I asked is because my older MBP 2.16 C2D (3 years old) seem to not have this issue or characteristic. I would even notice the vibration with my hand resting on the desk the new MBP sits in. This happens even with waking-up the MBP from cold sleep. As stated, no intense app or tasks are involved, just plain browsing thru safari.

Ok so I just bought this one, and it's really good.. One thing is quite annoying though... I don't know if it's really a problem or not so I wanted to see if others are having similar issues..Anyways..
By touching the alu parts it feels as if it's slightly vibrating a bit.. weird thing is sometimes it does it sometimes it doesn't... It's not bad but you know it feels kinda weird on the fingertips, So Is my keyboard defective or is this "normal" as in others might have the same issue?

I was wondering if any of you with the New Aluminum Macbooks feel any sort of vibrations from the hdd, or the fans. Especially, do you feel it near the trackpad, on the lower half of the computer?

I just received a new Mac Pro as a graduation present. During the intial set up of the machine, I noticed it crashed a few times. As time went on, I began to notice that it would crash anytime it would be subject to some sort of disturbance or vibration. My brother and I did a few tests and found that after tapping or pounding the tower, it would crash. My question: what is the source of the crash? is this a hard drive related problem? This isn't a big deal since it is brand new. I can just get it replaced if need be but Id like to know now so i can take the proper precautions.

I recently traveled to Europe with a MacBook Pro, and plugged it into the outlet with a travel converter. My understanding is that the brick on the magsafe cable works as a transformer and it is safe to plug into a European outlet. I've never had a problem with other laptops.
Everything worked fine with the machine, except I could always feel an "electric" sensation through my hands when touching the aluminum case. This was especially apparent when running my fingers across the top -- it was as if I could feel an electric current running through the case.
This seemed harmless, and I ran the computer without fail during my time abroad. My question is out of curiosity -- is this sensation normal? What exactly is it?

I recently changed the stock Hitachi 250 GB 5400 rpm drive to WD 500 GB Scorpio black 7200 rpm drive.
Now it was perfectly fine, no vibration or noise, just like the previous one. However now about a week past, I can feel it vibrating and that equals to the vibrations i get when I put a cd into my drive. It is kind of annoying. IS this normal? I know the drive is faster in RPM but as WD said it equals to 5400 by noise and vibrations and it was fine just a week back. (BTW Im running on a battery).
There is one thing though that bothers my mind, when I changed the drive, there were those 4 mounting screws which I didnt have screwdriver for. I took it from my friend but I think I did not screw one of the mounting screws to the very end. Can that be a reason?

Just received the new Macbook Pro 17" with I7 option as well as the 7200rpm HD 500gb. The machine works great so far. However, there is a slight vibration I can feel on the aluminum in front of the keyboard and basically across the machine, though when I moved it from a glass table to a wooden desk it was much decreased. The machine is also much noisier than I thought it would be, though I did know when I went for the 7200 option that it might be noisier.
Is this normal because of the HD or I7 chip? I can return the machine and exchange it, but the anti-glare screen seems ok with no pixel problems, etc., so I don't want to look for trouble without a benefit.
Is it possible this is not the HD? (vibration and noise does seem to emanate from the left side-I believe it is a Seagate, ID starts with ST)
