Smoking MacBook Pro Power connector

Hello, I am working on a 13" MacBook Pro for a coworker. She said one day she plugged in the power cable and smoke started rolling from the laptop near the power connector. She quickly unplugged the power cord from the computer and because it was 1 week out of warranty it got put in the cabinet and sat for a couple months.
Yesterday I disassembled the computer and the power connector board has some slight discoloring and there does appear to be a damaged component on it (it is small, looks kind of like a SMD Voltage regulator, but I'm not sure).
My question is this, Has anyone had this problem before and successfully fixed it? Is it just the power connector board or could there have been another failure on the mainboard that caused the connector board to fail, and subsequently cause a replacement to fail if I were to get one (I loked over the mainboard and it appears OK)? Could the power adapter have failed and caused this problem  ie over-voltage (the cord and brick appear to be in perfect condition)?
Thanks
-Brad

Normally when we get problems like these in we change both the power adapter and the power connector board

  • Macbook and Macbook Pro Power Adapters

    Is it safe to use a Macbook Pro power adapter in a Macbook and vice versa?
    I have just noticed that the MBP's adapter is 85 watts and the MB's is 60 watts. I hadn't realised they were different.
    My wife and I share each others adapters all the time (she has a Macbook). Will this be damaging either of the laptops?

    Shouldn't cause any problems. The main issue will be that the 60w adapter won't provide enough juice to both charge the MBP battery and run it if there is much of a load so I'd avoid using the 60w on the MBP for anything other than charging the battery whilst not using the machine - sudden power shortage could be painful for the machine.
    Best of luck.

  • I plugged in my macbook pro power adapter and heard a loud bang. I checked the charger by opening it and found out the charger blew the whole mother board up. So i buy another charger, as i live in Egypt, that blew up the same way, please help.

    You'll certainly need a new logic board.
    If I were you, I would take the machine into your local Apple Store or an AASP and have them evaluate the problems and give you an estimate for repair. If you're out of warranty, be prepared to pay a very high price to get your computer repaired.
    Good luck,

  • Using Macbook Pro Power Adapter on a Macbook

    I have a Macbook Pro and someone else in my family has a Macbook. Recently they misplaced their power adapter and started borrowing mine to use until theirs was found. I was uneasy about it, but it seemed to work okay. I know that the adapters are slightly different but will it hurt the Macbook to use a Macbook Pro power supply?

    It's fine. The MB will only draw the power it needs. FYI, the MBP adapter is 85 W, the MB's is 60 W.
    Hope this helps...

  • Macbook Pro power supply and grounding.

    Hey Apple people. I noticed something disconcerting with the power supply on my MacBook Pro 13" (non-retina)
    I have a stainless steel metal table in my kitchen. It is the same type of stainless steel table you find in restaurants.
    I have my 13" MacBook Pro in a Speck See-thru case.
    The MacBook Pro in it's case is sitting on a Rain Design "M Stand".
    The Rain Design "M Stand" is sitting on the stainless steel table.
    I am wearing a short sleeve shirt.
    I am sitting on a fabric covered chair at the table.
    The battery was getting low so I got out my power supply, which is the power brick with the two prong plug adapter.
    I plugged this into a power strip and the other end into the computer.
    While touching the case of the computer with one hand and leaning on the stainless steel table with my other bare arm. I felt a vibration through the fingers that were in contact with the MacBook Pro. I knew what was going on, and I got really concerned.
    I tried an experiment.
    I got out the extension cord that came with the MacBook Pro power supply and I changed out the two prong plug on the power supply for the extension cord. The extension cord has a grounding post.
    When I plugged the power supply back into the power strip and connected the power supply to the MacBook Pro. I no longer felt a vibrating sensation when I was in contact with the stainless steel table and the computer.
    I have other MacBook Pro power supplies and I always use the grounded extension cable with them, because it is located at my regular workstation area. This stainless steel table is located in my kitchen, and I was eating dinner and watching YouTube videos.
    Just thought you would like to all know that when you don't use the grounded cable on your MacBook Pro. you become the ground.
    Never using this power supply anywhere again without the grounded cable.
    Thank you for your time.
    Matthew Sievert

    It depends on what you are doing.  Yes, the power supply can get hot.  This is normal.

    My macbook pro power adaptor getting heated  & ultimately melting the coil which leads to power off.
    Is there any solution for that.

    I just have a try, I find my power adapter is very hot! But it is not the melting temperature.U can try to change another.

  • Macbook pro power adapter very hot- stopped working

    a few days ago I noticed my macbook pro power adapter was running very hot. Yesterday it stopped charging.   I switched the power cord 1/2 with 2nd one I had… it works but the adapter  is running very hot. do I need new adapter/power cord since my original cord is no longer working.
    suggestions please.

  • Cinema Display and MacBook Pro - Power Button won't work

    I have been using a 20" Apple Cinema Display (plastic model) with a 17" Powerbook and never had a problem. Recently I acquired a 15" MacBook Pro and it's like the power button on the display has no use at all. The only way to turn on the computer is opening the computer lid, turning it on and then closing it. The display also won't shutdown the computer, although the power button light reacts to the touch. The funny thing is that the display settings button work fine. Does anyone has a clue?

    Malcolm, thank you for the answer! But I still don't understand why my new MacBook Pro, having exactly the same connector as my older Powerbook had, won't behave the same way? I'm still using the same DVI to ADC adapter, I'm wondering if the new Macbooks maybe have some PIN assignment disabled on its DVI connector. And anyway, shouldn't the power button be able to at least shut down the computer, as long as pressing it would just open the shut down dialog box?

  • Dell 2407WFP MacBook Pro Power-Save

    I've just picked up a Late 2011 MacBook Pro 13" and attempted to connect it to my Dell 2407WFP monitor, via DVI with a genuine Mini DisplayPort to DVI connector.
    The monitor is working well as an extended desktop, however, when the system attempts to put the monitor(s) to sleep, the Dell gets stuck in a loop. It shows the "going into power-save mode" repeatedly, but never gets there.
    The monitor does seem to correctly go into power-save when the system is shut-down.
    I've read some similar threads, but none referring to this model.
    Any help would be much appreciated

    My Dell 2407wfp works fine with VGA, but I couldn't get it to work with DVI.  I narrowed the problem down to a faulty MiniDisplay Port to DVI adapter.  The Dynex brand one was not working properly and kept causing the monitor to attempt to enter power save mode.  (The Dynex adapter would get warm even when no cable was plugged into it!) I bought a genuine Apple adapter at Best Buy and now it works fine.  If that doesn't help try resetting PRAM (command-option-P-R  on start up).

  • Use MacBook Pro power cord with iPad?

    Hi all - if I remove the two prong AC plug from the iPad's power brick, the exposed connector looks like it will accept the extension cord that was included with my MacBook Pro's power brick. Is there any reason I couldn't use the Mac's cord with the iPad's power brick this way? I assume not but just want to be safe.

    Hi,
    Is there any reason I couldn't use the Mac's cord with the iPad's power brick this way? I assume not but just want to be safe.
    Not is correct.
    Only use the cables and the 10W USB Power Adapter that came with your iPad. Otherwise you could damage the hardware and void your iPad warranty.
    If you are running v10.4.8 on your Mac as your profile suggests, be aware the minimum system requirements for the iPad for Mac is v10.5.8 as noted here.

  • Macbook Pro power adapters and signal voltage

    Hi all
    I'm looking for fairly technical details about how a Macbook interacts with it's power adapter.
    My theory:
    If wikipedia is anything to go by,  when a Macbook power adapter is "on" but there is on load (no place to the send power, a.k.a the adapter is not connected to a device or the device isn't excepting power) the power adapter produces a single voltage of 6.86 volts (a fraction of the 16.5v or the 18.5v that is possible) that can inform a Macbook that a power adapter is available to draw from.
    http://en.wikipedia.org/wiki/MagSafe#Pinout
    From further observations of my Macbook Pro the charge indicator LED on the magsafe connector, when the power adapter is connected and the signal voltage is established as available, the power management within the Macbook Pro "thinks" for a moment and decides how much power it should draw from the power adapter.
    The issue:
    I figure that my theory is well reasoned but will more proof before I considered any off it fact.
    The most direct way to confirm my theory is to cut up a Macbook pro adapter and start testing. Yet getting and modifying a Macbook adapter to be a test subject costs time and money and asking the web for answers is cheaper on both accounts.
    Questions:
    Macbook adapters produced fixed voltages? Either signal voltage (6.86v ?) or operating voltage (18.5v or 16.5v depending on adapter model)? They don't produced a range of voltages?
    Is the signal voltage really 6.86 volts? How many amps or milliamps of signal voltage is needed from the power adapter for the Macbook to consider the adapter as "good" to draw from?
    Allen

    Shouldn't cause any problems. The main issue will be that the 60w adapter won't provide enough juice to both charge the MBP battery and run it if there is much of a load so I'd avoid using the 60w on the MBP for anything other than charging the battery whilst not using the machine - sudden power shortage could be painful for the machine.
    Best of luck.

  • My Macbook Pro power adapter is not working

    I have had my MacBook Pro for less than 1 year and I only use it to get to Uni and back. I leave the adapter at home and unplug it when I'm not using it, but lately it has decided that it doesn't want to work and hence I cannot charge my laptop. Is there anything I can do other than spen $90 on a new charger?

    If your computer is still under warranty, so is the power adapter. Make an appointment at an Apple store or call AppleCare.

  • MacBook Pro power adapter doesn't show green light when fully charged

    I've had a quick search through the communities and there are a lot of posts about chargers and indicator lights, but I'm not sure I'm really satisfied about my own issue so I thought I'd ask anyway.
    Basically, I bought a spare power adapter (genuine Apple 85W MagSafe2) for my new 15" Retina MacBook Pro in a store the other day, to save me lugging my main adapter to and from work all the time.
    Using it for the first time made me realise that the adapter I got with my MBP behaves slightly differently re: the LED indicators. The new one from the store shows amber until the MBP is fully charged, then solid green once fully charged. This I believe is perfectly normal.
    The charger I got with the MBP shows amber whilst charging, but only shows green very briefly when fully charged and then the indicator goes out completely. OSX (10.8.2) still indicates that it is connected to the power source though, and the battery doesn't drain or anything at this point - it definitely appears to be functioning as expected.
    Aside from this, I can determine no real difference between the two adapters in terms of charging speed or general functionality, they both appear fine.
    I just wondered if anyone else had ever seen this?
    I did reset the MBP's SMC settings too, but it made no difference. I'm inclined to think there isn't an issue with the laptop itself since the new adapter's indicators work exactly as I'd expect, but then again the original adapter seems to function perfectly so I'm wondering if there's just some trivial issue with the green LEDs or something like that.

    Really doesn't matter if anyone else has or has not seen something like what you have. Your original adapter is faulty in one way or another and you should take it in to Apple with your rMBP to show them what is happening and Ask Nicely for a new one that works correctly.
