Apple’s MacBook Air, which is lightweight 11.6-inch, has six separate lithium-polymer battery cells. In any of the laptop the battery is the main thing that rules it size and weight.
Ifixit today posted its typically thorough disassembly of the new MacBook Air. Their dissection revealed that the most of the space occupied by the six battery cells within the thin and lightweight machine.
The MacBook Air’s internal components are slightly different than the other 13.3-inch models coming from Apple.
This teardown details revealed that the MacBook Air’s 64GB of flash memory can easily disconnects from the logic board, but it is completely custom, and it means it is indicating that any other off-the shelf part cannot be successful to replace it.
This unique 64GB of onboard memory is made up of six main chips that is with four 16 GB flash memory chips and solid state drive controller from Toshiba, and a Micron OKA 17 D9HSJ DDR DRAM cache. Here, the proprietary solid state drive is just 2.45mm thick and weighs 10 grams.

The New MacBook Air matched a little with the current MacBook pros through using the same Broadcom Wi-Fi and Bluetooth chip. Only difference is, it comes in different form factor to fit well into the tiny frame of the MacBook Air.

A tiny internal fan is arranged for the machine to ensure the cooling factor. Also, this MacBook Air’s ribbon cable connection points were arranged with epoxy over them and this will act as a perfect insulator. Perhaps this initiation is to prevent some of the issues as if their protective plastic wears out over time.

Included on the logic board are the MacBook Air’s inter Core 2 Duo 1.4 GHz processor, Nvidia GeForce 320M graphics, and 2GB of Elpida J1 108EFBG RAM. Here, the RAM is permanently soldered to the logic board and it is indicating that it is not upgradable for MacBook Air.
