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 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.

  • Using MacBook Pro while charged?

    Hey
    I've got a 2010 15" MacBook Pro - just bought in September - and its awesome.
    Got a question though. Will using the MacBook Pro when charged fully, so theres a green light on the MagSafe Adapter, decrease battery life/health?
    Thanks.

    No. It's fine to leave it plugged in 95% of the time if that's most convenient for you. Just don't leave it plugged in 100% of the time: us it on battery power for an hour or two every day or two.

  • Is it dangerous using macbook pro while charging?

    Hi,did anyone experienced any electric issue when using macbook pro unibody while charging?When I use it during the recharge process the electricity pass trough my body.I can say that because one day when I was using it (with the hands on the keyboard) my girlfriend came and touched my face moving her hands on my cheeks and I felt a weird sensation like a vibration on my face so I unplugged the power cord leaving the hands on the keyboard (with palms near the trackpad) and I didnt feel it anymore.It is known that the electric fields can cause cancer.Am I in danger?I don't think it is a good thing that electricity pass trough my body anyway.There is any way to fix this problem?(a part of not using it while connected to the wall charger).Thank you

    Some people are more sensative to EMF's then others. If there is a bad connection in your house or in your computer, then you may experience this more then others.
    My guess is your house may have some faulty wiring somewhere and needs to be addressed. Get an EMF detector and see if you get spikes in the area of where your plug in your computer. Or rather, call an electrician who can check for these spikes around your house. Some houses, especially older ones, will have electrical problems, but even newer ones can have these since someitmes the laborer who installed it didn't know what they were doing or didn't bother checking.
    get a surge protector for your electronics, especially your computer deivces.

  • 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.

  • 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.

  • 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.

  • 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...

  • The battery for my Macbook Pro 13 "has only 121 cycles and is not charging anymore, my Mac is telling me that it is necessary to exchange it. You have any tips for me to find out what might be happening with my battery?

    Guys, i am actually trying using a solution provided by the article shared by dominic23,
    It says "Another option is to get an ionizer to help the atmosphere in the workplace be more conductive and pull charges away from contact surfaces, including yourself."
    So in my home, we have such device that could clean the air using ion, and i am using it in my room...
    Result: BANG!!! The electric shock on my macbook has gone!! I don't really care about physics but somehow it works! You guys should give it a try.
    Thanks again dominic23

  • My macbook pro is probably only 2 months old and there is a buzzing/grinding noise coming from the left side of the laptop every time I open it.  It may buzz 5 times in a span of 30 seconds then not make the noise the remaining time that it is open.

    My macbook pro is probably only 2 months old and there is a buzzing/grinding noise coming from the left side of the laptop every time I open it.  It may buzz 5 times in a span of 30 seconds then not make the noise the remaining time that it is open.  I have read that it may have to do with my fan or HD.  I am under apple care for a good amount of time but am wondering if this is a mjor issue.  I would not be able to get to an apple care center in the near future due to being at school.  Should I be worried or will it last by the time I am home in 2 months.

    Sounds like the disk in your MBP is accessing data on wake up
    If you are still concerned you can take it into the Apple Store where they can hear it to be sure
