Macbook Pro power brick heat.

Hey guys,

Just got a 13'' mbp retina on Monday and I've noticed that when the laptop is plugged in and charging the power brick gets extremely hot, like nearly too hot to handle for any prolonged period of time. Is this normal?

It depends on the load. If it's charging from low and you are using it while it's doing so, then it's going to get pretty hot, yes. Especially if you are doing something CPU intensive. Although with the Retinas just having the screen on would probably be enough.

Keep an eye on it. But unless you think there's a danger of it catching fire, I wouldn't worry about it.

Cheers. Yeah it's only seriously hot when its charging from low and I'm using it, when it's around 80% charged it cools down a bit and is grand when the mac is asleep while charging. Just wanted to double check.

Thanks again.

I have the 15inch retina and don't find this at all. Mine only gets slightly warm when it's doing something with flash or running a few programs.

Strange. I was thinking also, I bought the Mac in The States and have it plugged into an adapter here as it's got an American plug on it. Would that have anything to do with it?

They do get very hot when charging, and then drop back to being just a bit warm when charging is complete.

Nothing to worry about, just make sure that it's not positioned in a bad place when it's running hot (eg: if you use the Mac in bed, don't leave the PSU in folds of the bedclothes, etc).

The US plug has no bearing on things, but you might want to chop it off and replace it with a local plug, for convenience (unless you'll be visiting the US a lot).
