MacBook Air 11-inch (2012) teardown reveals upgraded hardware, same battery/internal design

Bill Detwiler tears down the 2012, 11-inch MacBook Air and shows you how Apple upgraded its hardware without changing the internal design.

The 11-inch MacBook Air is Apple's smallest, lightest, and lowest-priced laptop. The company didn't make any big design changes to the 2012 Air, but Apple did make several significant hardware improvements. In this week's episode of Cracking Open, I take you inside this year's 11-inch Air and show you what's changed and what hasn't.

Our MacBook Air test unit had a 2.0GHz dual-core Intel Core i7 processor, Intel HD Graphics 4000, 8GB RAM, a 128GB SSD, and a 11.6-inch LED-backlit display (1366 x 768 native resolution). It measured 0.68" (H) x 11.8" (W) x 7.56" (D) and weighs 2.38 pounds.

Cracking Open Observations

  • Intel 3rd generation (Ivy Bridge) processors: A 1.7GHz dual-core Intel Core i5 processor comes standard, but our test machine had a 2.0GHz Core i7.
  • Better graphics: The 2012 Airs also come with Intel's HD Graphics 4000—a step up from the older model's HD Graphics 3000 system.
  • More, faster RAM: The 2012 Air can support up to 8GB of RAM, compared to the 2011's 4GB. The chips also faster, 1,600MHz DDR3L SDRAM compared to the older model's 1,333MHz DDR3 SDRAM. As on previous models, the chips are soldered to the motherboard, which makes adding more memory impossible.
  • More storage: The new Air can be configured with up to 512GB of storage—twice the maximum capacity of the 2011 model.
  • 720p FaceTime camera: The Air's built-in camera can shoot 720p video.
  • USB 3.0: The 11-inch Air has two USB 3.0 ports, a single Thunderbolt port, 3.5mm headphone jack, and built-in microphone.
  • MagSafe 2 power connector: Like the MacBook Pro with Retina Display, the 2012 Air has Apple's new MagSafe 2 power connector.
  • Tamper-resistant case screws: Like previous Air models and the MacBook Pro with Retina Display, Apple uses special, pentalobe screws on the case's bottom cover.

A design that works

Despite all the hardware updates, the 2011 and 2012 11-inch Airs have identical internal hardware layouts. There's a large battery in the center, two speakers on either side, a small I/O board, single cooling fan, and motherboard. And just like this year's 13-inch Air, the battery is identical to last year's 11-inch model.

So what's not to like about the new 11-inch Air? Well, nothing too serious. There's no SD card slot, as there is on the 13-inch Air. The base model's 64GB SSD seems small given the machine's $999 price tag. And for those accustomed to a standard laptop, the machine's 11-inch may take a little getting used to.

Bottom Line

As is its larger sibling, the 2012 11-inch Air is a solid update to the line.

Just remember you can't upgrade it, so get all the RAM, storage, and processing power you'll need when you buy it.
