10 w power adapter leakage fault

If the power adapter for the iPad is plugged in the wrong way, there is an electrical charge induced on the metal chassis. It feels like a prickly, buzzing sensation. An ac voltmeter shows a low ac potential on the case relative to ground. Reversing the plug causes the phenomenon to disappear.  When connected through the adapter extension, the power adapter is forced to connect with the correct polarity, so there is no leakage. On a normal socket, the left hand, or wide blade receptacle, is connected to ground, while the other narrow blade receptacle is connected to 120 vac.  There must be some kind of internal fault in the adapter, a manufacturing or design error. I plan to return to an apple store to demonstrate this, and ask for a replacement.

Last year when the original iPad came out, there were a few reports from the UK of this. I thought this was resolved. Is this on an iPad or ipad2?
Anyway, I think Apple swapped out the power supplies when notified.

  • Could I have got a new power adapter for free?

    My power adapter for my mac stopped working recently and as far as I know I didn't cause any damage to it myself.
    I read the following on the apple website:
    Additional Information
    Whether your product is in or out of warranty, you can take your adapter to an Apple Authorized Service Provider or Apple Retail Store for evaluation and replacement if necessary. Pending the results of evaluation, you may or may not be eligible for a replacement adapter free of charge. Signs of accidental damage would negate any coverage. Be sure to bring in the computer used with the adapter; it is required to process potential adapter replacements.
    Which seems to suggest that even out of warrenty, if the charger has broken of it's own accord you can still get a free replacement?
    I took my adapter and mac to the shop, they said there were no signs of accidental damage but said I still have to pay for it. I referred to this statement from the website but they were very dismissive and kept saying it was out of warrenty. Perhaps i'm reading the statement wrongly.
    Just wondered if anyone could clarify :-)

    As you indicated, it depends on the results of the evaluation.
    Apple takes responsibility when design faults cause certain failures, especially when it represents a safety concern. There have been a small number of cases where failure met certain characteristics that Apple deemed that it should not have happened, regardless of age or use.
    I am reluctant to indicated the specificity of some of these issues, because for many reasons Apple would not want us speculating on the subject. Suffice it to say your product failure may not have met any particular characteristics associated with failures deemed to have extended coverage.
    If your product failed for an unknown reason, or apparently a failure stemming from age or normal life expectancy use, and it was after the normal expiry of warranty, then no further consideration was given. You need to buy and pay for a new one, unless you yourself, can provide extenuating circumstances to consider.

  • HP Pavillion DV4 1123us power adapter problem

    Hi,
    After using the HP Pavillion DV4 1123us for two years suddenly I noticed that the power adapter is not supplying power to the computer and it is making some not too loud repeatitive sound. I replaced the power adapter with HP 90W Smart Power Adapter which worked fine for a few weeks and then I noticed whenever I connect this to the wall outlet it makes some repeatitive chirping sound and this is also not suppying power to the computer anymore. It behaves like this even when it is not connected to the laptop which indicates that there is some problem with the adapter and not with the internal powers supply of the laptop. It is so surprising that the replacement power adapter stopped working so early.
    In my home all the other laptops are working just fine and and found all of them are two pin  - only these two are three pin. Not sure if this has gota anything to do with this fault.
    Any help on this matter will be highly appreciated.

  • Macbook pro Power adapter disconnects

    After charging the macbook and then disconnecting the power adapter, but I still leave the adpater plugged to the wall, it appears it just stops working or it shuts itself off. When I plug back in again after several hours there is no juice to the laptop. I have to disconnect from the outlet and wait for 5 minutes then I can get power flowing again. Not sure if it a safety feature or mine is defective. Can others verify this on their Macbook. Please let me know....Mark

    Went to apple store yesterday, they tested the adapter, of course it worked in front of them However whilst explaining the intermitent nature of my power supply a guy working in the 'genius bar' in the store said that his own MBP had the same problem, he had changed the adapter and it had been fine since. When my guy heard this an exchange was offered straight away and they even took one off the shop floor as they didn't have one in stock and I have to travel before they could get one sent. So the moral?
    Be lucky.
    p.s. Also mentioned excess heat - which the guy said they could fix if I left it with them, so seems they are well aware of the paste problem.
    p.p.s. shut down problems are the fault of software and should be remedied with a forthcoming update......(yeah right).

  • Ground loop with TV when power adapter connected

    I have a white Macbook (non-unibody) which I have connected to my TV with a mini-dvi to VGA adapter. I have done the same in the past with my Dell 1525 with no issues. When the Macbook is connected to the display whilst being connected with the power adapter, the screen has interference. After some googling I believe this is because of a ground loop. The monitor displays fine when the power adapter is removed.
    Since I am using some processor-intensive applications my battery life doesn't last long, and it is incredibly inconvenient to have to keep plugging the adapter in and out.
    Any suggestions on a cable to remove the ground feed or other solutions? I have already tried resetting the PRAM.

    You might need an electrician to check or replace the electrical outlet or wiring, if it really is a ground loop. Try temporarily plugging the TV and Mac into the same surge strip. If the interference goes away, then the fault is likely in the outlet(s) that the Mac and TV are plugged in to. (The surge strip puts both devices on the "same outlet" thus eliminating the ground loop between outlets in your home wiring. Of course, a bad or old surge strip could cause a ground loop as well so if you're already using a surge strip, try another surge strip in case the ground loop is in the strip.)
    Why don't you see it on the Dell? Likely because the Dell's power adapter has a transformer in it, which serves to isolate the electrical circuits between the devices. TVs and desktop computers often do not have this type of "isolation" transformer anymore, so ground loop interference can be more noticable. BTW, they do sell isolation transformers, but they're mostly for TV technician troubleshooting and not designed for continuous use. One that can handle a TV's electrical load can cost more than an electrician, so don't bother. You might be able to find a smaller, lower cost one to handle the Mac, but it still would mean a issue with the electrical wiring that may get worse over time. So IMO, better to spend the money on a electrician.

  • Macbook pro with retina display power adapter popped / exploded!

    I was just charging my macbook pro with retina display when a loud "pop" noise came from the power adapter and the red light on the magsafe2 connector went out. I unplugged it all immediately, but there was a burnt kind of smell and bit of black 'sooty' type material around one of the edges of the adapter!
    Thankfully the rMBP appears fine.
    I actually just got a replacement rMBP as the other one had a small scratch on the body. So both the charger and the rMBP that was atached at the time of the pop, will be returned in a few days anyway. Still I am a little alarmed by it all. The charger was plugged into a 6-way extension adapter with surge protection, so I don't think it was a power surge. And anyway my tv (also plugged into the socket adapter) was on at the time and there was no problem there. Can I assume it was just a fault in the adapter? I will tell them about it of course when I call up tomorrow to arrange the return. I just hope the same isn't going to happen with the new rMBP and charger!
    Has anyone else suffered a similar "pop" and broken adapter?

    Apple's warranty IS international. You have a one-year warranty when you buy the machine and you can extend that - and your phone support - to three years by purchasing the AppleCare Protection Plan, which is international as well.
    Good luck with your new computer!

  • Qosmio X500: power adapter stopped working for no reason

    Hi,
    Now i have my Qosmio X500 for a year and i like it, however i have small problems with it, and i would like to know if it can be problematic.
    The first thing is that my power adapter stopped working for no reason,
    So i bought a new one, but it always made some noise when the laptop was fully charged.
    I know people with the same laptop and their adapter didn't make that sizzling noise, it looks like it was already defect from the begin.
    Then i have one dead pixel in the middle of my screen, no problem for me.
    Finally my screen is a bit loose from the laptop, when i close it, i can move it, it always seems like it's not on it's correct place, because when i close it normally it's not 100% horizontal...
    Also when i replace my screen, my speakers make crackling noises and my webcam stops working.
    So all those problems i have annoy me, especially the last one (webcam and speakers problem), can this fit in the warranty of the laptop? I did extend the warranty for one year...
    Thanks in advance.

    > The first thing is that my power adapter stopped working for no reason,
    > So i bought a new one, but it always made some noise when the laptop was fully charged.
    I think this is AC adaptor fault maybe a broken cable or something like that I would recommend you to replace this get in contact with the dealer and ask for the new one.
    > Then i have one dead pixel in the middle of my screen, no problem for me.
    I found a info about such issues:
    +Information on screen technology and pixel failure tolerance for LCD displays
    +http://aps2.toshiba-tro.de/kb0/TSB9502LZ0000R02.htm
    > Finally my screen is a bit loose from the laptop, when i close it, i can move it, it always seems like it's not on it's correct place, because when i close it normally it's not 100% horizontal...Also when i replace my screen, my speakers make crackling noises and my webcam stops working.
    Maybe you should ask Toshiba notebook technicians for a check maybe some screws or the hinges are loose.
    The speakers should be checked with connected headphones. If you will not notice the same crackling sound using headphones, then the issue might be related to speakers

  • Mac Book Pro 17" 85W Power Adapter too Hot to handle while charging/using

    Hello All,
    I bought a Mac Book Pro 17". What's up with my Power Adapter when I am using the computer at the same time charging it. The Power Adapter gets so hot that it is too hot to handle...very very hot! Is this normal ?
    Any advise is most welcome on the matter.
    Mac Book Pro 17"   Mac OS X (10.4.9)  

    Simple answer, no its not normal
    The adapter should get warm, but not hot
    The first thing i'd do is try it in a different power socket
    If it still heats up like you say regardless of where you plug it in, then its a fault in the adapter
    return it to apple or an apple reseller and get another one
    i wouldn't use it any more as it could be dangerous to your computer and become a fire hazzard

  • All of a sudden even using the power adapter its only at 57% after 8 hours

    I have my powerbook 1.67ghz, its plugged in and i have a couple of adapters so i dont think it is the power adapter.

    Hi, Scott.
    yes i am using the 65 watt power adapter...
    Not when you ran System Profiler and got the results you quoted above, you weren't — at least not if System Profiler can be believed. Set the 50W adapter aside and don't use it with the Powerbook. If your alleged 65W adapter is identified by SP as a 50W adapter, it needs to be replaced with a proper one.
    If you "really never use it unplugged," that may explain why your Powerbook is misbehaving. Powerbook batteries want to be used. If you don't completely discharge and recharge your battery every two to four weeks, its charge-level calibration will become very inaccurate, and it may lose capacity faster than it should.
    http://www.apple.com/batteries/notebooks.html
    http://support.apple.com/kb/HT1490
    If the plug on the 65W adapter fits your iBook (i.e., if it's an iBook G4 rather than a G3), test the 65W adapter to make sure it charges the iBook battery properly. (This will do neither the adapter nor the iBook any harm.) If it does, it's almost certainly not at fault. The other three components of the Powerbook's charging system are the battery, the logic board, and the DC-in/Sound card. Plug the 65W adapter into a wall socket that you know is reliable and not switched. Reset your Powerbook's Power Management Unit, following the instructions in this article for your particular model. Connect the adapter to the Powerbook and let it charge for twelve hours without turning it on. Post back to let us know the results.
    Other questions:
    How old is your battery?
    Was this battery supplied to you under Apple's replacement program for original PB batteries within a certain serial-number range? Many of the replacement batteries issued under that program seem to have been defective. They lose capacity very rapidly and prematurely (which yours hasn't done) and/or they refuse to charge even when they appear to be in good health (which yours may be doing). If your battery was supplied under the replacement program, it falls under greater suspicion.

  • HP Business EVO Notebook NX7010: Power Adapter Issues?

    Hello,
    I have an HP Business Evo NX7010 Notebook and it has behaved strangely lately. When it is turned off it will boot up without being switched on. The trigger for this behaviour is inserting the power adapter plug. So I am guessing that the power adapter or the power jack has a fault.
    Also, sometimes the battery does not charge when the power adapter is plugged in.
    Would these problems be associated to the power jack or the adapter?

    Something cracked the power jack on the AC adapter open...it was not in the passive voice just "cracked". It takes some accident or event, When that happened and you kept using it you fried the motherboard. The pwer The laptop needs the motherboard replaced. I could try to sugarcoat, but that would not be honest. The power jack inside the laptop is not bad, it is the internal charging circuitry of the motherboard. So the light turns blue but nothing happens from there to the battery and to the motherboard itself.

  • Apple kept my Power Adapter!!

    How can I get Apple service to return my power adapter? I returned my 23" Cinema display because of light leakage to the Grove in Los Angeles. Unfortunately, because I bought it from a non-Apple source, they insisted on repairing it instead of exchanging it. I smelled trouble. The clerks weren't sure how much of the power cord to send back and debated it amongst themselves before deciding to give me the cord only, not the adapter. Now, my monitor has been returned without the adapter. I smell trouble again as I can't prove that they didn't give it back to me at the store or in the box with my monitor. Who do I write to on the small chance some techie has my spare adapter and is wondering where it goes? I really, REALLY hate the idea of having to buy another.

    Go straight to the store [again] call for the Manager and discuss it with him/her and the staff that served you that day, bring any paperwork that you may have regarding the repair.
    If certain parts shouldn't have been returned with the screen for repair they failed to give you the full picture on their policies. At least complain to their store manager
    Then if you're unhappy address complaints to Apple HQ,

  • Problem with power adapter?

    i just bought a new (refurb'd) power adapter about 2 months ago. the one that came with my iBook had been stripped a bit bare by my usage techniques so it wasn't connecting.
    lately (past 3 weeks) the adapter has been constantly switching from orange to green and back again while i have it plugged in and the amount it says is left fluctuates...about 5 minutes ago it said it had 59 minutes, now it says it has an hour and 5 minutes. right now, the charge is going really fast...it's never gone this fast (charge now says 52 minutes).
    any idea what i should do to fix this? i've tried calling my apple store but can't get through to a real person, and since it's a half hour away, if i can avoid going i'd like to (especially since i have been there twice already this weekend)

    Hi there:
    Well my first and really only guess is that your refurbed power adapter is at fault here. If your old one wasn't doing this then I would say the battery is not at fault here. Maybe try calling Apple. Sounds pretty frustrating. Hope it ends up well.

  • Battery is not charging Power source: power adapter

    I am very confused by my MagSafe power adaptor.
    Often I get : "Battery is not charging Power source: power adapter" with an orange LED on the adapter, Last time this happened the battery was 65% charged
    Right now I have NO led on "1:33 until full. Power Source: Power adapter"
    Sometimes, I get a dim green LED
    Each of these becomes normal on removing and reseating the adapter.
    The spring loaded pins are perfectly sprung and are clean. The receiving bit of the laptop is clean. The adapter clicks in perfectly. The battery is new enough (and this happened when the battery was replaced anyway, and beforehand).
    This happened since I got a new style adapter, the one where the cable is parallel to the Macbook, not the one where it sticks out at 90 degrees. I have two of these, and it happens with both.

    I let the battery drop to 71% and connected the cable. Orange LED.
    Now we are at 87%, just clicked up to 88% with No LED showing.
    0:52 until full (was 0:58 when it said 87%)
    Power source: Power Adapter
    I have done all the checks in the link you gave me, done them to the letter. Pins look good, receptor looks good. My lead is the L shaped one. The adapter is the 60W one
    89% now, 0:49 until full

  • MBP discharges battery even while power adapter plugged in.

    Just recently, my MBP started discharging its battery even while the power adapter was plugged in. Eventually, it goes dead and shuts itself off, then starts recharging. I've turned off bluetooth and airport, going to a wired/plug in mouse, but that doesn't stop it, nor does changing to "better energy savings" while on Power Adapter. While it is going down, time of course remains "Calculating until full" -- I've checked the pins, and even spent 3 hours yesterday driving to the apple store, waiting, getting a new batter from the genius, and driving back home. Then it happened again with the new battery this morning, after it was fully charged last night.
    Any suggestions? thoughts?

    Have the MBP repaired via AppleCare. Just let them know what it's doing. I'd guess at a fault in the charging circuit, but this is obviously not normal behaviour!

  • AC Power Adapter issue with new (refurbished) ibook...

    I just got my refurbished ibook today and went to plug it in and test it, and then wanted to charge the battery on it. At first I thought it wasn't doing anything when I went to turn it on (it made the starting sound but the power button didn't turn on or anything), but then after trying a couple times, I noticed that the black screen had a faint image of an apple on it. I had the screen too far to the front for me to see it clearly (as it's an lcd screen) and later when setting my preferences, I had noticed the brightness was just too dim which I adjusted...
    So the power button never did glow when it was turned on (at least I didn't notice it after I got it booted up). My adapter's plug fits loosely in the socket on the laptop but still glows green, but all the time... Isn't it supposed to glow orange when charging??? Well I was setting up everything and did my power management settings as well, and as I have it set up to show me my battery level on the desktop, I was noticing that it was depleting (at what I would guess is a normal pace for my current settings), it started off around 83% and had gone down to 58% or so after about 1 and a half hours with highest settings basically. But my power adapter was plugged in the whole time... Shouldn't it be using my AC power and not the battery's?
    So I turned it off and now it is sitting there (hopefully charging), but that little green light on the adapter where it plugs into the laptop is just that, still green...
    Does all this mean that there is a problem with the power adapter and its ability to actually charge my laptop? I got this refurbished (from TigrfDirect) with a 1 year warranty (from Apple) so this should be covered, but as I just received the thing today, I really don't want to have to deal with a messed up AC Adapter...
    Also, I haven't even yet checked the battery itself to see what # it is and if it is one of the ones that is part of the recall or not... I would hate to have to do that and not have a working AC Adapter, though of course if the adapter is't working, I can't charge the thing anyways, so I guess I would have to wait another few weeks with dealing with Apple and the warranty issues anyways.
    I looked in the help section and the only suggestion they had for if your battery doesn't charge is to take it out and put it back in and then attach the adapter again. I guess I could do that at the same time I check on the battery's recall status, I just hate opening my computer up as soon as I get it. Also the battery cover is not totally flush with the rest of the case, one corner sticks up a bit, and I think it was a replaced item as it doesn't have the little LED lights that the computer says should be there to tell me how much the battery is charged (unless this is UNDER the cover for some reason, but the cover is bright white compared to the rest of the ibook coloring, so it seems as it was just a basic replacement cover used)...
    Ok, so thanks for any input you might have. I will let people know in a couple hours if the ibook has actually charged at all during that time or not...

    So I did the reset button thing and it didn't do anything at all... If I plug in the power adapter without the battery the laptop will not turn on at all, so I am guessing that it definitely is the adapter and will have to contact Apple to somehow get a new one. Oh great, tomorrow's Friday and isn't this a holiday weekend? Which means it will probably take even longer to get them to send me a replacement adapter... You think that buying a refurbished mac would mean that they would have tested out all the parts/components first before reselling it...
    And so while I was at it, I checked on my battery's model # and serial # and it is one of the ones on the recall list. I think I was right that it had been replaced (now that I know that the battery is part of the back cover) which would probably explain the recall battery as this is one of the older ibooks and should have been one of the lucky ones made before the ones on the list... I did get to see the lights (only 3 though) flash solid green for about 3 seconds when replacing the battery back into the laptop.
    One good thing did come out of this... As I was taking the keyboard out to find the computers serial # (I already filled out my form for the new battery), I was surprised to see an Airport card. Not that it would have surprised me too much in the first place except that it wasn't listed in the details/parts list when I bought the laptop. It was also listed that my laptop had a 10GB hard drive (while the picture on the website showed a 30GB one). The box it came in said 30GB as well, but I just dismissed that. I had went to see how much space I had left on the HD to see that it had 13.99GB and this is after any formatting, and the install of OS 10.2.8 including OS 9.2.2... So a few added bonuses to help make up for the fact that it is NOT is as good shape as I was expecting (or should be to even be sold as a refurb IMO), and the fact that the AC adapter is completely faulty.
    I just hope that I can get a new AC Adapter soon, so that I can at least be able use my laptop with some kind of power until the new replacement battery shows up. This must be some kind of terrible joke. I get the laptop to be able to use it for a few hours and then have it be without ANY kind of power for posibly up to 2 months? I seem to have the worst luck with Macs, which makes it strange as I have never had any problems with all the PC's I have ever used (and I started using computers when I was 4) but I have now had an imac die (possibly the HD), an Apple studio monitor start flashing on the screen possibly due to connector problems, and now this (and all within 2 months). I am almost ready to just give up, but I have spent too much time and money on all this mac stuff (and all for my obsession with OS X) to do it just yet.
    So please tell me macs aren't always this horrible, or else I will have to make up my own commercials where PCs are better because at least they turn on and boot up for more than 1 week (I think I had the imac working for about 5 days total before it would boot with errors).
    Or some kind soul could also mail me a working AC Adapter that would work with my ibook (if you happen to have a spare), so I could get to do more on it other than changing it's settings... I now only have 40% battery life left. I don't think I should even turn it on again as the boot up alone would drain away too much precious juice...
