Ok, now this is interesting.

True to form, the cool cats at iFixit performed a complete teardown of Apple’s newest instant-on, 11.6″ MacBook Air and found now less than six separate lithium-polymer battery cells.

The internal components are slightly different from those found in the 13.3″ model, a prototype of which was spotted before the device was even revealed on Wednesday. That larger MacBook Air has four separate batteries, which are bigger and provide up to 7 hours of active battery life.



In its teardown, the solutions provider found that the onboard 64GB of flash storage easily disconnects from the logic board, but the part is completely custom, meaning an off-the shelf part cannot be used to replace it.

The unique 64GB of onboard memory is made up of six main chips (four 16GB flash memory chips and a solid state drive controller from Toshiba), and a Micron OKA17 D9HSJ DDR DRAM cache. The proprietary solid state drive is just 2.45 mm thick and weighs 10 grams, while the previous MacBook Air’s hard disk drive was 5.12 mm thick and weighed 45 grams.

The new MacBook Air also uses the same Broadcom Wi-Fi and Bluetooth chip found on the current MacBook Pros. However, to fit into the tiny frame of the MacBook Air, it comes in a different form factor.

All of the cooling of the new notebook is accomplished with a single, small internal fan. Ribbon cable connection points found inside were also discovered to have epoxy on them that acts as an insulator, perhaps to prevent issues if their protective plastic wears out over time.

Included on the logic board are the MacBook Air’s Intel Core 2 Duo 1.4GHz processor, Nvidia GeForce 320M graphics, and 2GB of Elpida J1108EFBG RAM. Just as with MacBook Air models, the RAM is soldered to the logic board, making it non-upgradable.

If you’ve picked up the new MacBook Air and have any impressions of it, let us know.

Late Thursday, Apple released a new beta for its forthcoming Mac OS X 10.6.5 update. The new build, labeled “10H562″ was released to developers late Thursday as a 616MB delta update. According to the release notes, there are no known issues. With new builds coming steadily for several months now, the update is expected to arrive in advance of the November release of iOS 4.2.

Per AppleInsider, the seed note accompanying the build specifies Printing as a “Focus Area.” 10.6.5 will work with iOS devices running iOS 4.2 to enable the new AirPrint wireless printing functionality. 10.6.4, the last update to Mac OS X 10.6, came in June with fixes to Adobe Creative Suite 3 issues and a resolution for unresponsive keyboards and trackpads.

Stay tuned for additional details as we get it and if you’ve gotten your mitts on the new build for testing, let us know.
