First of all, as always, it is best to have on hand a good kit tool to start dismantling the MacBook Air.
After removing the bottom cover of the MacBook Air we again see a very careful and neat design. The batteries are the same used in the 2011 model and according to Apple provide a range of up to 7 hours.
The SSD storage module is also similar to that used in the 2011 model, but the connector is changed. A small plaque provides USB 3.0 connectivity, the connector MagSafe 2 and the other uses an ordinary audio module.
Another interesting part is the trackpad of the MacBook Air, because as discussed is a fairly easy piece to replace. We are back with a system that is impossible to upgrade both RAM as well as its FLASH storage, so you have to take that in consideration when you decide to buy it because then there is no turning back. The new Airs are being marketed by Apple as having much longer battery life (12 hours on the 13-inch model), Intel’s new, faster and lower power Haswell processors, and a much faster SSD than the previous generation laptops. Apple’s products never score high for repairability, and the new Airs are no exception. The claimed faster all-flash storage has been achieved by switching from a SATA to a PCIe SSD. So overall, if you’re about to purchase a MacBook Air it was worth waiting for the improvements included in the latest model.

As it turns out, the official word from Apple on the MacBook Air's battery replacement program may be even more dismal than some feared. Gizmodo opened up a MacBook Air review unit from Apple (tsk tsk!) and learned that it's pretty sexy on the inside.

For over 13 years, Powerbook Medic has been providing parts, repair, and service for a variety of gadgets. Today we will do the same but with the baby of the family, the MacBook Air, for more detailed on its internal components and distribution of its parts. Highlights include batteries that occupy much of the computer and as something new, the cooling design is based on a single fan. In this case it is a 128GB module which is based on a SandForce controller, although the Toshiba name is written on the storage module. For the WiFi connection they are using a Broadcom BCM4322 802.11n for Bluetooth connection they are using a Broadcom BCM20702. The purpose of this design is to minimize the sound of the air flow and you barely hear the fan noise. As you can see it only has a heatpipe and a copper base that makes contact with the processor.
But unlike the MacBook Pro, MacBook Air does not have protection for the LCD screen in order to save weight. You still need a special tool to get the case open, the RAM is soldered in place, and many of the components are proprietary. The old model used a Toshiba SATA-connected SSD, but Apple has called upon its rival Samsung for a PCIe SSD part this time, which also managed to be smaller than the one used in last year’s Air.

The iSight camera cable connector has been removed, and the dual microphone design is just a simple extension to last year’s component. But make sure you get the options you want when purchasing, as there’s no way you can upgrade components later on. While the $129 cost of getting a battery replaced is more or less the cost of the battery itself, owners will reportedly need to send their MacBook Air off to Apple for about a week to actually get the job done. It also shot a video (which Apple has requested be taken down, for now) of going through the actual process of replacing the battery, and it is apparently pretty simple. In that time, over 300,000 orders have left our facility for US and international destinations to help save old devices from the landfill and bring them back to working condition. This is completely normal, because the MacBook Air does not carry a dedicated graphics card and requires no cooling for other components, only the processor.
The updated components inside are also different sizes to the previous models, meaning you don’t have an upgrade path. Finally, the heatsink now extends to cover both the Haswell processor and platform controller hub, which is a better cooling solution than last year’s Air. AppleInsider recounts that the process involves removing 10 screws underneath the machine to get the bottom plating off, then another nine screws to unleash the battery.
Used parts designated with a Grade B condition may have slight damage such as small dents or deep scratches that are noticeable but should not affect the functionality of the device.
Assuming that a third-party offers a battery replacement eventually (or Apple relents and provides the kit for home users to do this themselves), the MacBook Air's battery situation could soon look a little brighter for those planning to keep one for the long haul.
