Firmware Updates Address Charging Issues With 2007-2008 MacBooks and MacBook Pros


Apple today released a pair of firmware updates for 2007 and 2008 models of the MacBook and MacBook Pro, addressing an issue with the machines not charging properly when used with the new "L-shaped" MagSafe power adapters.

This firmware update addresses an issue with certain MacBook and MacBook Pro models from 2007-2008 that prevents them from charging with new power adapters.

According to a support document on the issue, the following models are affected:

- MacBook (13-inch Late 2007)
- MacBook Pro (17-inch, Early 2008)
- MacBook Pro (15-inch Early 2008)
- MacBook (13-inch, Early 2008)
- MacBook (13-inch, Late 2008)

Apple initially used the "L-shaped" MagSafe adapter for the MacBook Air, as its slimmer profile and cord orientation enabled the connector to fit the notebook's form factor without hindering its ability to rest on flat surfaces. With numerous complaints from customers regarding fraying and overheating issues with the original "straight-style" design used since MagSafe's introduction, Apple has now transitioned to the L-shaped MagSafe design for all of its notebook models and standalone adapters.

I've always preferred this style over the classic magsafe connectors.

I haven't had this issue with my late '07 MacBook.

I do like the new design though. Very nice.

Lately with my Aug 08 MBP, I have to really make sure the amber light is on when it's plugged in. It's almost like it's not being seated correctly, although usually just a wiggle turns the light on. When the light's off, it isn't charging.

I have the "straight on" magsafe charger. Not sure if I get the update, or if this will even help. I hope so.

Why is the charging brick for the new i5's so much bigger than the charging brick for the MBA?

Same thing with me. What it most likely is would be something stuck in there... since its magnetic it attracts all kinds of things. Also very hard to clean out..

Rats, when I first saw the title, I was hoping it would fix the abysmal battery life I've had since moving to Snow Leopard in my Early 2008 MBP. :(

Actually this sounds like the beginning of the end of your adapter. The straight on adapters do not last long, they begin to fray inside the plastic casing and eventually they short and melt the plastic casing usually at the end that plugs into the laptop, but I also had one fray at the power brick end. Do not leave it plugged in to your laptop when you are not home or are sleeping, it can start a fire. I have not had any of the straight on adapters last more than 18 months before this started to happen, and I have "babied" the adapter to try to prevent this. If you look around online you will see this is a common problem with these adapters.

What happens if the update is disturbed? Is it possible for a laptop to get bricked?

Interesting. Genius Bar replaced my MacBook Pro's charger last week because it was charing intermittently (didn't have any problems with the replacement). Wonder if this could have been he problem. :confused:

As an aside, I'm not too fond of the "L"-shaped MagSafe connector... found the connector included with my last MacBook much easier to connect (I think because the former adaptors were less loose).
