macbook pro electric shocks

Wear Rubber Slippers on your feet while using your machine. This cuts you out of the circuit and you wont feel anything..Atleast that is what helped for me.

I have a 2008-2009 MBP and I have the same issue, not having it when new though..

I think someone might have put "pp in the coke"

Only Apple would get this kind of forgiving response from it's users. I can't think of another manufactureer on the plannet who would get away with selling a product for several thousant £/$ and (to avoid recieving an electric shock) users would be happy to wear rubber slippers, or keep their feet off the ground, (as another poster suggested!).

BTW I have the same problem, solved by using the 3 pin earthed UK lead instead of the travel plug.

I use the long power lead, my mac is earthed.. Yet, I have the same problem. So, it's not the powerconnecter you use. Then I realized it was my extern HD when plugged in (I only had it on specific places, specific outlets), and today I used the same outlet to plug in my printer and the problem was back. When I removed the usb, I started getting shocks from the usb-pin. I'm a student, so I called the University where I plugged in all these devices. They tested it and it was actually the electric outlet (a splitter). So watch out with outlet splitters. I tested it on my room, and I had it again when they all were connecten the same splitter. (yes, with a pin connection, everything was earthed.)

I have felt a feeling like that when I put my arm on the left side of my MBP, but only if it is very hot.

Small matter compare with what device you have Mac is such a power full machine ever build.

try not to let your foot touches the ground. 🙂

Soooo, this has been bothering me like crazy for the past couple of months. It especially started happening when I moved to another appartement, and I finally have the solution.

My AC-outlets here are not grounded, but I thought I would have to use a grounded AC-adapter anyway. But it kept shocking me (I actually measured it at 80 volts, for people who would like to know 🙂)

So the solution is:

When on a grounded power outlet, use the grounded AC adapter. When on a non-grounded outlet, use the duckhead-adapter OR replace the clipon-extension chord of the adapter with a basic ungrounded one (you can get them in any electronics-shop, it's one of those things that usually plug into those big block PC-adapters. It should have a flat plug) if you would like more length than the short adapter.

Also, always use grounded power adapters for peripherals (printers, hdd's etc.), and ungrounded ones if you are on an ungrounded outlet. Otherwise the grounding will still want to go through your body.

It's actually basic electronics 101, but it still got me a while to figure it out.

If you still experience shocking on a grounded outlet with a grounded plug, try switching to an ungrounded adapter (the duckhead one), it could be that your power outlet, or grounding in the whole house is defective.

But, last of all: It's bloody annoying and I really don't get why Apple decided to do it this way.

I've had this problem forever, and glad I finally googled it. The mac genius said it was in my head basically. But at work, plugged into the grounded cable adapter, no shocks. At home there's always a low level shock. Hence the genius appt. The solutions make sense, and the comments about apples business model. The reason I just googled this was I thought something was biting my leg, like a horsefly bite would feel, dull then stinging, but it was an 1/8 stereo cable I use to hook it up to speakers, and the cable was draped over the desk and lightly tapping my bare leg. Of course, with my hands and forearms resting on my macbook.

My question is: Does anyone know if these shocks would damage a phone if it was hooked up for hours a night sometimes? I had an iphone that just stopped worked in any kind of useable manner - actually a couple of them since this "new computer" and I'm just curious if the amount of current would be sufficient to hurt an iPhone - or any other gear.

I recently bought my first mac a Macbook Air and you guessed it when plugged in it tingles which I found a little alarming. I was advised today to book it into the genius bar at my local apple store. It was fascinating to see how most of the staff felt the tingling case except one. Also with all the posts I see here I find it unbelievable that none of staff admitted to having seen this problem before. I ran my hand along several macbook air and pro computers in the store and only one tingled. I realise now they were probably all plugged in with the earthed 3 pronged plug. Thank you all for the information..

I have this problem too on an early 2013 mbp. The information on the ground loop stuff is helpful, I am glad I found this thread.

apple i know you see this you just removed my post

just fix my 2500 euro macbook

i used apple mac's all my life

Why are you replying to a two and a half year old post? Don't be so lazy and start a new thread giving exact details of your Mac, system and the issues you are having.

All the best.
