The MacBook Air contains six battery cells that occupy nearly all the space inside the new super-slim laptop.
iFixit took the 11.6-inch model apart to reveal the six batteries that provide up to five hours of wireless working, as well as the tiny components that Apple has squeezed into the remaining space.
Those include the four 16GB flash chips that comprise the 64GB of storage, which at just 2.45mm thick and weighing 10g is half the depth and less than a quarter of the weight of the hard drive in previous Air models.
iFixit also discovered that scarcely on part in the new model can be replaced by the user. Although the flash chips are removeable, they’re a custom design so cannot be replace by off-the-shelf units. The 2GB of RAM is soldered onto the logic board, so that cannot be upgraded.
Apple has even used a peculiar screw — a five-point “Pentalobe” — to further frustrate tinkerers. The same screw is also used in other Apple products, notably the iPhone.
