Electric shocks from macbook pro

I have had my MacBook Pro since november and at first wondered, why my fingers would sometimes tingle, when using the touchpad or just resting them on the area besides the touchpad. I though there might be cooling fans underneath this area, and it was vibrations i was feeling.
But after setting up my working space next to a radiator, i get small but painful electric charges, when some part of my arm touches the radiator while using the macbook. That is probably because the radiator is grounded and the tingling from the macbook pro has all along been electric discharges.
I don't know how strong these electric shocks are, as i have very little grounds for comparison - i don't go around experimenting with electricity and pain.
But is there any danger to myself or the computer or is it just harmless static electricity like what occurs when wearing the wrong shoes with the wrong carpet? If this cannot be answered from my description, then how do i gather more information?

As an addendum to this phenomena it has been noticed (on laptops with metal casing) that small electrical shocks and/or tingling can be felt if using the laptop on battery power with mains powered periferal equipment ie external hard drive, plugged into the usb or firewire ports. This is caused by insufficient grounding on the manins powered device and can be rectified by using the laptop with the three-pronged mains lead.

Electric shock from MacBook Pro while charging only.

I got this painfull shock as if you have been pierce by a needle to your forearms.
The shocks are actually from the screws at the side of the MacBook Pro. You can test it by the following method while the power plug are connected.
1. Extend your forearms and let it touch with the screws.
2. Use a "Test-Pen" and touch all the screws. It will lighted up !! Even the "On" button has it.
You won't get it if the MacBook Pro are running with Batteries.

Actually, the users guide does state: “The AC power
cord provides a grounded connection." (page 30) and,
“For best results, always use the AC power cord and
connect it to a grounded power outlet when one is
available.” (page 31).
The term "grounded" should be put it the simplest form of explaination so that it will be better understand for other user who might not know it.
Just a suggestion....
"The AC power cord provides a better protection if you experience uncomfortable electric tingling sensations while operating the MacBook Pro" (page 30) and , "For best protection, always use the AC power cord whenever possible." (page 31).

Electric shocks on Macbook Pro

Hello to all,
I'm having issues with my brand new Macbook Pro (it has less that two weeks), I get this annoying electric shocks near the dvd drive and the keyboard. This is quite often, in 15 min. I got three electric shocks.
Since it's not normal I ask you if you have any problem or suggestion about this, the Apple support in my country is restricted and probably get another Macbook Pro will cause me more problems since I need to install and move all again.
I have call my local Apple support and they could not help me much.
Thank you for you help!

"I have call my local Apple support and they could not help me much."
Why not? Not even advising you to take your computer to a repair shop for a look-see?
Personally, I would not put up w/any type of "shock" coming from a computer. If I were you since your computer is still under warranty, I would call Apple Customer Service in your country.

What Should Be Done About Electric Shocks from MacBook?

I very recently purchased a MacBook. I had not been using it long before I realized that it is not uncommon to get an electric shock when I touch areas other than the keyboard. Now via Google and this Discussion Board I find that the shocks are a known issue and that Dell also has this problem with some of its aluminum constructed laptops and that MacBook Pro users also receive shocks. Assurances are given that the shocks do not hurt the computer, but what about the user?
I find it very disturbing to think that the shocks will be ongoing. I would not have purchased the computer had I known about this problem. I admit that it may be more disturbing to some people than others, but it is of considerable importance to me. I feel it should be mentioned to customers before a purchase decision is made. Can/should the computer be returned?

That must be a strong electric current to cause a plastic-based laptop to cause electric shock. As the previous poster above me stated, as long as the system is grounded, there shouldn't be a problem for aluminium based laptops.

Electric shocks from Macbook

I don't know if anyone else has experienced this, and what you did about it. My macbook when charging gives small electric shocks through the body of the mac. I'v been on the phone to Apple and they have suggested using a 3 pronged plug, which i do. using a serge protector, which i shouldn't have to use. They told me the magsafe adapter is not earthed if not using the extension lead, which seems mad to me. Please post comments if you have experienced similar problems and what you did to sort it out.
thanks

"i would have thought apple would sacrific design for userability."
Without the low current leakage, Apple's products could not be sold. The design compromise is an INTERNATIONAL concern, not just Apple's.
"I dont experiance it with any plastic cased computers."
That's because a plastic case does not conduct electricity.
"It is within regulation for the voltage on the case but non the less its a big compromise to make. By rights there should be non, or low, aspecially when the product is such a high value product!"
"Rights"? I'm not following your thoughts. Too, you are not following mine. Expensive or cheap, the same design considerations are necessary.
Even in today's economic climate, Apple, all of its competitors, and all of their strategic manufacturing partners are looking for brilliant engineering talent. If you can solve this design compromise with an intelligent, economically-viable solution (they're looking for something better than "make everything plastic"), there's a job waiting for you.

Shocks from MacBook Pro

I recently got a new MacBook Pro 15 and I am experience shocks on my for arm right along the edge. More so on the left side but I have even felt them on the right along the seam where the top meets the case. Any one else have this experience and what is Apple doing to help with this situation? It does not seem to happen whenever I am in the Apple store so no techs can experience it, but it never happened before with my old computer using it in the very same locations.

do you mean a continual shock/tingling when you touch the case? or just when you first touch the case after walking around? i get alot of static shocks when i touch my MBP after walking around/rubbing against suede lounge/etc, and that's normal cuz unlike most plastic-cased laptops the MBP has a metal case that's earthed directly to the mains earth - nothing to worry about.
but if you're getting a continue tingling, investigate further! is there anything else plugged in? you may have an earthing issue...

Shocks from macbook

I get electric shock from my macbook and my headphones (iPhone 5 headphones) begins to loose the sound.
I see it as a serious problem. I've had it for three years and now it give me electric shocks when I have my bracelet close to my Macbook pro.
I have thought to report the matter, but I wanted to contact you before to see what it may be due. And what you can do about it.
Excuse my English, it is not the best.

OK. Make sure you are using the 3-prong AC plug (not the one with two). If you are still getting shocked I would take the machine to an authorized Apple dealer.

RF electric shock from airport on MBP APPLE PLEASE INVESTIGATE!

Other people have been posting reports of electric shocks from the case of a MBP when the mains charger is connected and battery is near 100%.
I have the same issue. HOWEVER I think that this is in fact related to the AIRPORT card. (I have a phsyics degree and I used to work as a broadcast engineer for a major UK corporation so I know a bit about RF.) The type of shock being received feels to me exactly like an RF shock. It is most noticable if you touch the edge of the case or one of the corners with the soft flesh on your under arm and presents itself as a sharp tingling/pricking/burning sensation.
The other big clue is that if you create as shock and then get a friend or colleague to disable the AIRPORT (as I did) then the shock STOPS at exactly the moment that the AIRPORT connection cuts out.
In metal macs the case and frame become part of the RF aerial and I am pretty sure that what is happening is that the radiated or received power from the 2.4ghz wireless netwoork is just getting powerful enough to cause this VERY UNPLEASEANT tingling shock.
It doesn't happen all the time and it does seem to change according to the position of the machine in the room... all of which seem to support the RF theory as moving the machine about will change the RF signal strength.
PLEASE APPLE you NEED to investigate this... and fix it, because quite apart from the fact that it makes using the MBP with bare arms a rather nasty experience if it does turn out to be RF related it could also be something of a health and safety issue.

Hi, I'm a Radar Engineer and licensed Radio expert for the last 21 years, and I am certain that the MacBook Pro is NOT an RF Hazard! I do have the equipment at work to measure it , so I will give it a quick test - just to confirm!
You could do a quick test by switching-off the Airport Card using the upper Menu bar icon

it is almost certainly a mains live-voltage leakage due to the power adapter not being connected to a good (enough) earth. Possibly your adapter will need to be checked to ensure that the leakage currents are in the safe range of 10 microamps to a couple of milliamps, but they normally all give a bit of leakage. The more powerful the adapter - tends to give slightly more leakage. it is a tiny , tiny current - but in europe it is at quite a noticeable hundred volts or so!
My Panasonic Sky Box gives exactly the same feeling, but of course I don't often type things on my Sky Box!

Electric shock from S10 model

We have a one year old (just out of warranty) S10 idea pad. We have begun to experience small electric shocks from the case of the laptop. The source seems to be the front right corner.
Has anyone experienced this and determined a solution? Is it a power cord issue?
Thanks.

It could be the ac adapter.
The inner sleeve of the plug on the adapter should be hot and the outer sleeve should be ground. There should be no voltage on the outer sleeve. You could have somebody check it with a volt meter. If you read any voltage at all on the outer sleeve, it's shorting.

ok - since you'll be sharing it with a PC - connect it to your windows pc - then format from there - instead of NTFS format - choose exFAT.
or, you can read the link below on how to do it in dos mode.

once you've formatted it - you can now use it in both your macbook and windows computer.

How do i transfer my data from macbook pro to iMac?

i just bought a iMac. How do i transfer my itunes library, photos, files via bluetooth from macbook pro to my iMac? Much thanks for your help!

I believe that when you boot your computer for the first time and you are following the onscreen instructions you are prompted whether you want to transfer data from an old mac or PC. If you click 'transfer from an old mac' and follow the onscreen instructions, this may work.
If you have already skipped this step you could use iCloud to transfer data. If you make sure that everything you want to transfer is synced in iCloud, this may also work.

What audio cable do I need to hook from macbook pro to an amp?

Yeah, just wondering if any audio cable will work to hook from Macbook Pro (10..5.8) to an amp? Not skilled in this area at all! thanks!

It would help to know what inputs your amp has, what outputs your computer has, and what you are trying to accomplish.
