Macbook Pro Magsafe Power Adapter is very hot. I never noticed this before. Is this normal?

Has anyone experienced this? Is it normal to have this adapter soooo hot?!

Warm to touch is normal.

Macbook pro magsafe power adapter - cord melted

Has anyone had the cord on their power adapter burn or melt through? I've had my Macbook Pro for 3+ years and taken great care of it. I experienced the battery bulge issues and has two batteries replaced under AppleCare. I came home yesterday to find this:

Any ideas?
I realize I'm outside of my AppleCare now but I still find this alarming.
Thanks.

I would take MBP & Magsafe to your local Apple Store or AASP. Otherwise, see the following KB Articles;

Macbook Pro Magsafe Power Adapter

Hi,
I recently have bought a new Macbook Pro 13". Will using its charger (model no. A1344) to charge my white Macbook (late-2006 model) damage it? The white Macbook's charger is no longer functioning and I didn't buy a new one… Do you recommend buying a new charger for white Macbook? I just don't wanna end up with a new laptop and a damaged charger..
Thanks...

Power adapters for Intel-based Apple portables are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple portable, you can use an adapter of a higher wattage without issue.
For instance If you have a MacBook (13-inch Late 2009) that normally uses a 60W adapter, you can also use an 85W adapter with that computer. You would not use a 45W adapter with that computer; it would not provide enough power for that MacBook. Using an adapter of higher wattage than the adapter that came with the computer will not cause the computer to charge more quickly or otherwise operate any differently than using the adapter that came with the computer.

TS1713 my power adapter gets very hot on my mac book pro is this normal

my power adapter gets very hot to toutch on my mac book pro is this normal

Hot is normal for the charger but very hot is not. If it were mine It could be that your MBP is drawing too much current. I would take it to the Apple Store and have it checked out.

MacBook Pro Retina power supply is surprisingly hot

The power brick seems to get a lot hotter than my previous MacBook Pro power supplies. Anyone else noticing this?

Just got my new 2013 retina MPB, and the powersupply is charging the battery in the MPB at an amazing rate (faster than 1% per minute) but holy Hephaestus batman that power brick gets lava-hot.
This is my 10th Mac laptop (personal) and none of the other power supplies have ever heated up like this. Other Mac laptop power supplies got very hot but never too hot to touch. This retina power supply, at the temp it was at earlier today, would cause burns if left on skin. So hot I am concerned about the plastic melting. Will check but I would not be surprised if when all the lights are off there isn't a slight glow to this lava powered adaptor.
My retina seems to love it and it does not get hot in the least. As i typed this message, the charge went from 40% to 67%. (freekin awesome) and the power supply is very warm but hot yet.
I cannot help but wonder if this is not related to the powersupply on house wiring with the reversed phase... My brick does not get hot all the time and not everywhere I plug it in.

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

Late 2008 Macbook Pro: Which power adapter?

Hello all. I have a Late 2008 Macbook Pro 15", MacPro5,1. A few months back my dog ate the power adapter (unplugged, thankfully.) I thought I did the proper amount of research to order the correct adapter from a third party on Amazon, because I'm pretty darn broke and need to save every penny I can. When I got the adapter, the connector was different from the one that came with my Macbook Pro. It was 85W, all the numbers matched up, but the style was different. But, the plug worked enough to let me get the work done that I needed, so it didn't concern me too much.
That is, until this cord just stopped working. That's what I get for getting a third party cable from China off Amazon.
So now, I'm trying to research again to make sure I'm getting the right cable, and I want one that's made by Apple, and is exactly like the one that came in the box when I bought my Macbook Pro new. I went to MacSales.com and checked their compatibility pages, and ran into some issues. What is showing as compatible with my Mac is the 85W Magsafe MC556LL/A, but this is shown with the incorrect connector (like the one I got off Amazon.)
When I looked at the other adapters that were available, I found the MagSafe 2 85W MD506LL/A, which has a connector that looks like the original, but it only shows as compatible with 2012+ Retina Display Macbook Pros.
So, do I have to buy the MagSafe that is not like the original that came with my Macbook Pro, or can I get the MagSafe 2 that does match what I got out of the box?
Reference pages from MacSales.com:

Thanks! I didn't realize there was a revision, but that makes sense. I guess I don't understand they would change it, then use the original design for the later Retina Display models. Oh well, as long as it works!
On a similar note, is OWC the best option for a cheap Apple-brand adapter? They're selling them for $47, when the cheapest I can find anywhere else is like $75. They seem pretty reputable with all the options and Apple-specific stuff they offer, I just didn't want to make the same mistake again and would like other options if they are available.
Thanks again!

Macbook Pro 13" power adapter

I bought my Macbook pro 13" from someone around Christmastime last year (who bought it only a few months prior) and it works great. However, my power adapter is dying and my AppleCare and warranty are up. It's very finicky and only works about 10% of the time anymore. It's the newer model of adapters that are round and thinner than the old flat rectagular adapters. Could I buy the older model for my Macbook and it'd still work? Or do I have to buy another newer model adapter?
Thanks!

I recommend getting the one designed for the unit to ensure long-time reliability.

The power adapter gets very hot. Any suggestions?

The power adapter part that plugs into the computer gets very hot. I have replaced the battery and replaced the power adapter. It also has a hard time connecting and recharging the battery. Is it possible to change out the plug in part in the computer and is it expensive? Does it sound like this is what is needed to fix it? Its about 3 years old. Any suggestions would be appreciated. Thanks.

Hot is normal for the charger but very hot is not. If it were mine It could be that your MBP is drawing too much current. I would take it to the Apple Store and have it checked out.

MacBook Pro 17" power adapter lights orange when NOT plugged into laptop.

My MacBook Pro power adapter lights up orange even though it is not plugged into a device. When I do plug it into my laptop it remains the same and does not charge. Due to this my laptop is now dead. What does this orange light mean?

You should take both your MBP(Macbook Pro) and your power adapter to an Apple Genius bar or an AASP(Authorized Apple Service Provider) for a free evaluation. This is a strange occurance, and it seems that it may be a hardware malfunction.
Make an appointment so you don't have to wait too long.

Use macbook pro on power adapter or on battery?

Is it recommended to use my macbook pro with the power adapter plugged in or using the battery? how does it affect the battery?

http://www.apple.com/batteries/notebooks.html. i keep it plugged in most of the time. i use it on battery only when i need to, or at least 1-2 times a month.

MacBook Pro using power adapter but not charging.

My MacBook Pro is plugged in w/the power adapter, the green charging light is on, but my battery percentage is only showing 15% and is not increasing. It was actually at 60% this afternoon...went to 22% and now is @ 15%.

Could be bad battery or faulty charger or faulty charging circuitry. Take it to an Apple store or AASP.

Macbook pro 15' power adapter not working

When I was using macbook pro 15' early 2008 this morning, the power adapter suddenly did not work. The led light on the power adapter blanked and the status bar showed that I was using the battery. I am sure about the power adapter is fine cause I try it on another macbook pro and it works well. I have tried to take off the battery and the power adapter for 30 secs and then press the power button. But it does nothing good. I have tried to press the option + command + "R" + "P" and power button to reset PRAM. But the problem is still there. Now I have run out my battery what should I do ?

Welcome to Apple Discussions
It sounds like the power board inside the MacBook Pro has failed, best get it to an authorised repair centre.

2ghz intel core duo macbook pro 15 power adapter

What is the model number for the correct power adapter for this laptop?
Which models will work? There are 60w and 85w.

The 85 W model is for 15" MBPs. Either of the two listed on Apple's Online Store will work.

New Macbook Pro Penryn Power Adapter Whine/Buzz

Hi all,
While I was using my new 15.4" 2.4Ghz MBP Penryn last night I heard a high pitched whine coming from the area. I tracked it down to the power adapter that was plugged into the wall. I tried it on several different outlets in my house and heard the same amount of whine.
Interestingly, that if I have the adapter plugged into the wall, it doesnt have to be plugged in to the MBP to hear the whine. This is reassuring as it doesnt appear to be anything from the MBP causing this.
Has anyone else heard this type of whine from a apple power adapter?
Jeff

I do not know if we are talking about the same thing, but I wanted to at least add my situation to the thread to help others in narrowing down the issue. I am experiencing a strange buzzing issue right out of the gate with my new 2.5Ghz MBP. It is on the right side and is a constant low pitched buzzing that sounds either like a fan or hard drive. The best analogy to a sound would have to be the noise a loose wire, on a home audio system for example, sounds when not properly connected. This noise is pretty annoying in a quite environment and not something I could say sounds appropriate. I have never heard such a consistent noise in the in the nine years I have been using apple notebooks.
I called apple care today and they said it is increased fan speed due to the smaller chips and higher processor speed, which is total bs considering I just had a 2.4Ghz MBP. I am slightly irked by the fact that customer support would come up with pretty pathetic explanation such as that and obviously bothered by this noise even more.
