Macbook Pro Power Adaptor

I need to order a replacement power adaptor for my macbook pro. The writing on the old adaptor is worn. Cost indifferent, should I purchase a 60W or 85W? Thanks!

Apple Macbook Pro Power Adaptor

I was using my Mac this morning and when I plugged in my power adaptor to charge my Mac. I heard a spark from the outlet and I took out my Power Adapter. Then I realized that the Power Adaptor seemed to be warmed up at the front. Then I went to the other room and plugged in the Power Adapter to a different outlet and I guess the Power Adaptor's wire inside or something like that got messed up and it was no more charging my Mac.I bought my Mac last Summer. To be exact, about 10 months ago. But I bought it from Texas from Frys' Electronics. I live in Toronto, ON, Canada. So I don't know if I make an Appointment in the apple store, they're gonna be able to help me out getting a new one. I just wanna make sure before making an appointment...

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.

NEW macbook pro power cord not working

I just bought my macbook pro 3 weeks ago and for some reason my power cord is not working to charge the computer. There doesn't appear to be any damage to it and I've tried plugging it in to different outlets etc. and no luck. I noticed one day that it was blinking on and off from charging and not charging and then the next day it just stopped working completely. Is this a common thing? Should I just go buy a new one?

Welcome to Apple Discussions!
Your power adaptor is under warranty as well as your new Mac. If it isn't working, Apple should replace it for free under warranty.
You might want to try resetting the SMC:

This is likely the first thing they would do at the Apple Store, and it may well solve the charging problem.
Good luck!

MacBook and 17" MacBook Pro Power Cords Interchangable?

Can I use the adaptor/charger (both are MagSafe) from my MacBook on my 17" MacBook Pro? Is it safe? Will it harm the the battery?

You cannot. The MacBook Pro uses an 85W power adapter, while the MacBook comes with a 65W adapter. You can safely use the MBP's adapter with the MacBook, though.
MacBook Mac OS X (10.4.7)

Macbook Pro power issues; Dim charging light, limited power.

So I'm having some serious concerning issues with my 15" MBP while connected to AC power. Recently my AC adapter gave out so I bought a replacement on ebay. While waiting for it to arrive I used a borrowed a 65W charger to charge between uses, which as I understand should not be an issue especially when only charging. At some point the charge light on the 65W began showing only a very dim green. It still worked fine on the Macbook.
Upon receiving my new adapter and plugging it in, I observed the dim light again and decided to try and see what was going on. The system profiler registered a charger present but not charging, but the battery seemed to charge regardless. When using the computer on AC power, battery life would decrease slowly and it would eventually fall into sleep mode when the battery hit zero. Something that seemed to be accelerating from what I imagine to be the battery on its last legs as it had been giving a "Service battery" warning for a few months before this. Eventually the computer began to shut down and attempt to restart immediately on startup with the battery, and operated on AC only, without the battery, as long as I didn't use any applications that demanded high performance from the CPU.
I have tried resetting the PRAM and SMC with no avail.
Well, I just received a new battery in the mail (not that I expect it to fix the main issue), and I'm hesitant to try to charge it.
Basically, what I'm wondering is should I be worried about damaging the new battery with what seems likely to be a damaged charging circuit?
Also, from what I gather, this problem is usually related to the left I/O board where the magsafe and charging circuit is.
Is there any way to determine where the fault is for sure before I go buying replacement parts? My hope right now is that it is in fact the I/O board and not the logic board because of the cost of a new logic board and the fact that I could easily replace the I/O myself.
Any insight at all is greatly appreciated.

Here's a link for troubleshooting the power adaptor:
http://support.apple.com/kb/TS1713
Also check for any debris in the power port which may be keeping the adaptor from making good contact.
It's always possible the power adaptor from EBay is faulty. You need to try a known good on, like a working one that a friend has or one at the Apple Store.
Is the new battery a genuine Apple battery or a third party battery. Third party batteries can be difficult to get working. I have one from OWC that's like that--it takes its time to begin charging instead of starting to charge in a second or two.
The best way to troubleshoot all this is to try a known good battery and a known good power adaptor. Your new ones are still in unknown condition. If you have a friend with the same Mac who has known good battery and power adaptor, you can try those in your Mac--and yours in the other Mac, and narrow down the possibilities.
If the Mac fails to charge even with a known good battery and power adaptor, there's a good chance that the I/O Board is bad. But I don't know of a definitive test that would tell you for sure.
Good 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.

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?
