    hey guys,

    either it's a newbie's tendency to worry but my magsafe charger for my 2010 15inch i5 MBP is getting way too hot for comfort.

    nothing has corroded (yet) but the magsafe itself feels extremely hot to touch after 30mins or so of use.

    is this normal or is it time i give Apple a call?

    They do get very hot. Especially when charging and running near 100% CPU. It's normal, I wouldn't be concerned until I saw it melting or smelled something burning.

    Not to worry... It's normal for the magsafe adapters to get pretty hot to the touch. I've had 3 different magsafe chargers and they all are exactly the same. It's alarming at first but you get used to it.

    thanks for the assurance :)

    Does the adapter hum also?

    I've seen a few threads about the magsafe adapter (for my 2009 13" MacBook Pro) getting really warm - I've noticed a low buzz/hum from the adapter when it's hot as well - it's making me really nervous!

    Is anyone else noticing this? Thanks!

    Hi, sorry to revive am old thread here but I just want to ask for clarification on something. Is it normal for the magsafe adapter(the one that plugs into the wall) to get hot or is it normal for the actual magsafe connector that goes into the computer to get hot. Reason I ask is because my Macbook Pro 13 2010 magsafe connector gets really hot and the heat sort of spreads to the whole back left of the unibody. I'm just trying to figure out if this is what everyone else is experiencing. Thanks!

    Hi, sorry to revive am old thread here but I just want to ask if it's normal to snuggle up to my Magsafe charger for warmth when the room is too cold, sometimes even putting it in my shirt. Am I the only one who does this? Guys?

    Absolutely. When my feet get cold, I just go to my trusty Magsafe. I hate socks, but with your Magsafe, you don't need them.

    lol, well it was colder in ottawa the other day, but as I sit here typing this it is currently -41C, for the americans thats around -42F, very cold haha.

    LOL, I just do it once and a while, and not really to warm up actually, just feels nice:p if you know what I mean. It kind of just happens.

    Random as heck, but for those curious, -40c = -40f :p The one time it matches up.

    I had experience the same problem megasafe 2 plug to my MBP retina 15" getting too hot to touch after searching and trying for sometime I find the best solution to unplug the cable from the laptop turn it 180 degree then connect it again it works like charm.

    Not unusual - more especially if you're using the Mac while it's charging. A 15" MacBookPro should be using an 80w charger. If it is the 60, it's probably working to full capacity while still not keeping up as it should (as an 80w would) -although, there is no issue otherwise using a 60w, if that happens to be the case.

    Wow, I have no idea how this is possible, but it really works. The adapter is still a bit warm but nothing compared to before. Thanks a lot!

    The chargers get very warm.

    You can see here http://pinoutsguide.com/Power/magsafe_power_pinout.shtml that with all other things being equal reversing the adaptor is not going to make one bit of difference.

    Perhaps your laptop is under different load or finished charging? Or maybe you have a fault with the charger or laptop? In the latter case I would recommend you keep your eye on it because reversing the adaptor is not going to permanently fix that.
