Will the MBA Magsafe adapter/power supply work on an MBP?

Similar, but inverse question to this thread:http://discussions.apple.com/thread.jspa?messageID=6167022
From looking at several high res photos online, I can see that the MBA angled plug may be physically identical to that of the MB and MBP. So, mechanically it's all good. What about electrically?
I don't really care about needing to charge the battery at the same rate as the 85w supply. I just want something smaller for use during class (3-4 hours); I usually charge my Macbook Pro overnight anyway (or keep it plugged in).
Thoughts? I suppose I'll have to go to an Apple Store with my 'Pro and figure it out in person otherwise.

I'd be VERY wary of doing this. No problem using an MBP charger (with its higher possible capacity ) on the MBA, but using a lower capacity power adaptor might result in overheating and consequent damage to the adaptor, with the further slight possibility of shorting resulting in the high voltage side making its way to your MBP , with disasterous results .
Pulling out the battery when using the MBA adaptor might let you just about get away with running it safely, but I personally wouldn't risk it. I don't even like to use our 60W MacBook chargers on the MBP.
(I see in the other thread that some people are suggesting that the 85W charger might "overpower" the other computers. As ricktoronto has suggested there, this simply isn't so. The excess ability simply won't be used.
Using a low capacity charger / supply, like the MBA one, in a situation of high demand , on the other hand, can result in real problems, Overload can result in internal component failure or fire in the power supply. My bet is that Apple products will be pretty well protected against such things though).

  • Will this video card and power supply work on my computer? HP Pavilion p6213w Desktop PC

    I have a HP Pavilion p6213w Desktop PC, will this video card and power supply work on my computer?
    Video Card: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=8379339&sku=A455-0760
    Power Supply: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4668507&sku=C13-2511
    Any help is greatly appreciated, thanks.

    It is unlikely that the power supply will fit/work in your HP Pavilion p6213w Desktop Computer. Please consider the Corsiar CX500, CX500M, CX600, and CX600M for your power supply needs. These power supplies are the same physical size as the factory unit and are known to fit and work in most HP full-sized consumer desktop computers.
    There is a chance that the GTX 760 and other current generation video cards may not work in your computer. These newer cards typically require the computer to support the most current UEFI standards and many motherboards don't meet this criteria. Please know the return policy on any video card you purchase, in case it doesn't work. If the GTX 760 doesn't work, consider the GTX 650/660 Ti or equivalent AMD graphics card for your graphics card needs.
    If you have any further questions, please don't hesitate to ask.

  • HT1349 Is the Apple Magsafe 2 Power Adapter covered under Apples one year warranty?  I cant figure out how to check the date.  The serial number is to long to enter.

    I need help finding out warranty information on the Apple Magsafe 2 Power Adapter.  When I enter the serial number, it is too long for the box.  Any help would be appreciated.  Thanks.

    I got this from my father.  It looks like it is an aftermarket package and not something that came with the original Mac. I will try to attach a picture of the item box and the barcode label.  The actual part number is MD506LL/A .

  • Netra 120 - Will a SunFire 120 Power Supply Work?

    Thanks in advance for any help with this question.
    Will a SunFire v120 AC power supply fit/work in a Netra 120?
    I dont have a DC power source for my Netra, and would like to replace the DC power supply with an AC one. Will one from a SunFire v120 work?
    Alternately, anyone know a cheap DC Power source that would work to power the server?
    -allan

    In answer to my own question, yes. I put the AC power supply from a SunFire v120 into the Netra 120 and it works just fine. This is probably the only difference between the two servers.

    JCGood1984, welcome to the forum.
    The computer should take a standard ATX power supply unit (PSU).  I suggest measuring the existing PSU and compare the measurements to the one in the links.  If the measurements are the same, it should fit.  I don't know anything about the brand, however.

  • Will the lightning USB adapter work with regular USB jump drives?

    Will the lightning USB adapter work with regular USB jump drives?

    Not really.
    Technically, with some USB drives (I've had a 50% success rate) you can import photos or videos off the drive - thi those photos or video follow a very strict naming convention.
    But you cannot import anything but photos or video and there is zero support to write off the iPad to the flash drive....so while it technically may work, it's so limited to effectively not work.

  • Does anybody know if it is ok to use a standard travel adaptor with macbook magsafe 85w power supply?

    I am moving to New Zealand and want to take my macbook pro with me.
    I have a Magsafe 85w power supply.
    I am aware of the apple travel kit.
    Do i need to purchase this, or is a standard travel adaptor safe?
    Do i need a lower watt magsafe power supply?
    Should i get a grounded 3 prong adaptor rather than the ungrounded 2 prong adaptor that comes with the apple travel kit? Particularly with long term use.
    Thank you all!

    The item that is crucial is the connector to the AC outlet.  The power adapter will work from 100 to 240 volts.
    Ciao.
    A grounded plug is always preferable.

  • Will the EVGA GeForce GTX 760 SC work on my h8-1360t with Formosa motherboard?

    perhaps a silly question but will the EVGA GeForce GTX 76 SC work on a FORMOSA motherboard?
    This question was solved.
    View Solution.

    Sticknrudder, welcome to the forum.
    Not a silly question at all.  It is difficult to know which video cards work in which computers these days.  I had to do a lot of research, including phone calls to EVGA and XFX'es Tech Support.
    In this instance, the video card will not work in your computer.  All of the EVGA video cards from the GT 640 to present require a full UEFI BIOS in the motherboard.  HP didn't begin using a full UEFI BIOS until mid-October, 2012.  Your computer was released in July, 2011.
    Also, most of the newer cards will require a power supply unit (PSU) upgrade.  Unless, that is, you chose the 460W or 600W PSU when you bought the computer.  Even the 460W may not have enough wattage for some of the cards.
    MSI makes a video card with a hybrid VBIOS that has a switch to choose a Legacy or UEFI BIOS.  There is a video in the link that I provided just below the picture of the card.  Paul from Newegg does a good job of explining the card.  I suggest contacting their Tech Support to assure that it will work in your computer.  It is 9.84" in length.  I suggest making a template the size of the card to assure that it will fit into the space provided if they say that it will work.

    I suspect not. 4G frequencies are carrier specific in the US. I am unaware of any iPad models specifically for any European carriers. From what I've read, 3G data will work in Europe, but I won't know for sure until my trip to Tuscany in the summer of 2013.

    I will use my 110V MacBook in the Philippines which has 220V sockets. Will the World Travel Adapter Kit help me?

    Assuming you're in North America now, you probably won't need any sort of plug adaptor there; most sockets in the Philippines are the same as those in North America. In case you do, it doesn't contain the correct adaptor.
    Voltage conversion is handled by the MacBook without any additional components.

  • Will the new final cut pro x work with my Final cut pro version 6.0.6 data

    will the new final cut pro x work with my Final cut pro version 6.0.6 data

    Thanks Tom.
    So I will need  upgrade to FCP 7 first, then convert to an XML file in 6.0.6, then convert to another file that FCP X can read? I have a lot of half done projects that need finishing. Is this process very complex and time consuming?
    Maybe I should be approaching this from a different angle. The reason I am asking is that I now need to upgrade to a new Mac book pro and have been told that I cant run final cut pro 6.0.6 on the new models using maverick. Is this true?

  • Will the New iTunes 11 for Windows work on Windows 98???

    Will the New iTunes 11 for Windows work on Windows 98???
    A. True.
    B. False.

    My opinion is no. Apple has no plans updating version 11 to meet the needs of Windows 98 being that #1 - Windows is pushing forward with their Windows 8 operating system launching in a week and iTunes 11 would have needed to be re-written from scratch to accomodate the Windows 7 and Windows 8 systems. It is a known issue that iTunes is bloated and most Windows users will use other media players to manage their music rather than iTunes. #2, Windows 98 is so old that even Windows does not recommend anyone using anything past XP as you are exposing your PC to viruses or anything that no longer can be patched. I highly recommend upgrading to atleast to Windows 7 and this is of course if your PC matches the bare minimum of hardware to use iTunes 10.7 and 11. You are actually doing more harm than good by using an outdated OS.

  • The output of a power supply in labview using a Magna Power LXI over RS232 to simulate a periodic voltage.

    How can I toggle the output of a power supply in labview using a Magna Power LXI over RS232 to simulate a periodic voltage?  Any help would be apreciated?

    LXI is Ethernet communication.
    Does the power supply have an RS232 port?
    Are you looking for an RS232 to Ethernet (LXI) Converter
    https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=rs232%20to%20ethernet%20ip
    But to simulate a periodic voltage you need to send the SCPI "Source" command to the power supply in a loop.
    Changing the Voltage setting in periodic value.
    How fast of a periodic voltage do you need?
    You may be limited to how fast LabVIEW, Windows and your power supply can respond to commands.
    Use VISA writes. It is the same for LXI as it is for RS232. The LabVIEW code would be the same.
    After you select the corrent VISA Ref, either a com port or an IP address, LabVIEW does not care if it is LXI or RS232.
    From a Magna manual I found
    Command Syntax
    [SOURce]:VOLTage[:LEVel][:IMMediate][:AMPLitude] <nrf+>
    [SOURce]:VOLTage[:LEVel]:TRIGgered[:AMPLitude] <nrf+>
