MacBook Pro AC Adapter on MacBook?

Is it safe for me to use my spare MacBook Pro AC adapter with the MacBook? The wattage is different but I never had a problem doing this with the PowerBook 15" AC adapter on my 12" iBook.

Check out Macworld's advice (http://www.macworld.com/2006/05/firstlooks/macbookfaq/index.php):
I already own a MacBook Pro—can I use the power supply that came with it on a MacBook?
If you hold the two power supplies side by side, you’ll notice that the MacBook Pro’s is larger. That’s because the MacBook Pro uses an 85-watt power supply, while the MacBook uses a 60-watt power supply. Apple says you can use the more powerful, 85-watt power supply with a MacBook without any problems, and that in 80 percent to 90 percent of situations, you can use the MacBook’s power supply with the more-demanding MacBook Pro as well. If you’re really taxing the MacBook Pro’s processor with some heavy-duty work, the MacBook’s adapter will still be able to power the MacBook Pro—but it may not have any power left over to charge its battery.

  • 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,

  • The Pro's adapter?

    Can I use the new unibody Macbook Pro's power adapter for charging my older white macbooks battery?

    Yes the Yoga 3 Pro power adapter is a USB charger too!
    How does it work?
    The special "fool proof" charging cord has two extra pins on the AC adapter end and two extra pins on the Yoga 3 Pro end. The extra pins only make a connection when the fool proof cord is plugged in to the Lenovo charger and the Yoga 3 Pro. When a regular USB cord is plugged into either the charger or the Yoga 3 Pro, it makes a regular USB connection.
    Can I charge the Yoga 3 Pro with any USB charger?
    No. The Yoga 3 Pro requires 2A at 20V, which is what the provided 40W Lenovo AC adapter supplies.
    Can I charge a USB device with the Yoga 3 Pro AC adapter?
    Absolutely. In addition to 2A at 20, the Yoga 3 Pro AC adapter supplies 2A at 5.2V (10.4W), enough to charge a phone or tablet. Works for iPad.
    Where can I buy spare AC adapters and cords?
    AC adapters with cords are sold in the accessories section of the Lenovo store.
    Where do I find the part numbers for the AC adapter and cord?
    Look for AC Adapters In the PDF Yoga 3 Pro Hardware Maintenance Manual.
    What are the USB specs of the Yoga 3 charging port?
    It's a USB 2.0 port. It provides enough power to charge an iPhone, but not enough to charge an iPad. If you want to charge an iPad, try the USB 3.0 port on the right of the Yoga 3 Pro.

  • Integrated Intel Iris Pro graphics adapter in boot camp

    Hello
    How can I use integrated Intel Iris Pro graphics adapter in boot camp on my new Haswell Macbook pro?
    It is really important in order to get decent battery time.
    Best regards
    Jesper

    For some odd reason Apple has restricted Mac computer from using that graphics adapter when you are using Windows and your Mac has a add-on, discrete, graphics card installed.
    If you do a google search on it no one has been able to make it work on a Mac.

  • What's with the Yoga 3 Pro power adapter - it's a USB charger too?

    absolutly agree, no chance to buy this cable in NZ. What a bad service. If anybody has a link where to buy one for ANZ would be great.

  • 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.

  • 15" MacBook Pro Power Adapter gets very hot.

    I have a 15" MacBook Pro that I am using the older charger with the adapter from Apple.  The adapter is getting to a measured 137.9 degrees, a.k.a. HOT.  Anybody have any thoughts on this?

    A lot of people report this. Try turning the connector 180 degrees and cleaning the terminals. Apparently that helps in most cases

  • Replacing the MacBook Pro Power Adapter Port

    There's a short in the adapter port. I have to keep the cord sitting just perfectly to make sure it's running off the adapter or off the battery. The battery has needed to be replaced for a while so when the adapter shorts and it switches to battery power it will shut down before I notice.
    Any idea on how expensive it is to replace this adapter? I've never had anything on the inside of my macbook repaired. I bought this 4 years ago so I'm hoping it's not the end.
    Thanks.

    Some people on the forum have used the Pros for their MacBooks and had no problems.

  • 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...

  • 13 in macbook and macbook pro power adapter

    I have a macbook from late 2006 and a new macbook pro 13 inch. The power adapters look the same and have identical specs printed on them as 60 W adapters etc. The tech specs read as identical power supplies also. Are they indeed interchangeable and identical?

    Yes, you can use them, no problem!
    I had a Black MacBook from 2006, and I use that power adapter with my 13" MBP all the time. Its great because I can keep one at home wired to my desk, and one in my bag. I no longer need to unhook things. Its so nice to have an extra!

  • 2010 Macbook Pro Power Adapter broken?

    We have a 2010 Macbook Pro 13" that was working perfectly fine since we bought it last June. What a surprise, just out of the 1 year period and suddenly the power adapter starts to malfunction. One day we noticed that the charger was plugged in but the light wasn't on and the battery icon showed the computer wasn't charging. I unplugged and replugged the plug into the wall a few times and finally the light came on and the computer showed a charging symbol. The next day when we plugged the charger in again the light again didn't turn on and computer was not charging. We tried jiggling the plug and replugging it and after many tries was able to get it working again. This has been going on for a few days now.
    Today while the laptop was plugged in, it suddenly crashed, rebooted itself, and the date/time was reset to many years ago. Wifi didn't seem to connect for a while, but eventually it did and it seemed the date self corrected. Tonight, we have been unsuccessfull in coaxing the charger to work and finally decided to post here. Since we are out of our 1 year limited warranty, we are no longer eligible for Apple Care or charger replacement. Do we have to shell out the $79 for a new adapter? Is it really the adapter that is broken, and not the macbook? I've seen some other similar issues posted on the board but didn't really find a solid answer to the problem.

    This has happened to me too, at least a couple times.  I think that one problem is the power adapter cord is not designed for repeated twisting and bending.  It should be, but it isn't.  From now on, I will be gentle with it and that may prevent failure.  Be careful with the LED (green/yellow light) end.  Do not bend it much from the end to a couple inches from the end.  Apple's peripherals (ear buds, power adapters, etc.) do not measure up to the standards of its iPods, iPhones, and computers.  They never have.  It's frustrating.

  • Macbook Pro VGA adapter resolution issue

    I have an Optoma projector that has been connected to my Lenovo laptop for the last 2 years. I have just decided to set my mac up to it, and had a mini display port to VGA adapter. The native resolution of my projector is 1280x800, yet when I plug in the mac, I can only get 800x600. If I change it to optimize for the built-in display, I get a scaled image of 1280x800 on what is really 800x600. This has been extremely frustrating and my searches on the web have proven unsuccessful. I have tried the PRAM/NVRAM restart where you hold Option, Command, P + R, and it has not resolved the issue. How can I display the correct resolution, which is exactly the same as the Macbook itself??

    Upon more research, I have learned that holding down the "option" key while clicking Scaled in the Display Properties will allow you more resolutions to choose from. I now have the option of 1280x720, 1280x768 or 1280x960, but still not the true resolution which is 1280x800!! How ridiculous! Why can't the MacBook determine the resolution of the projector and use it to its maximum potential the way Windows did?
