Introduction
C'est à nouveau cette période de l'année où la nature s'éveille (pas que) : le MacBook Air est sorti de l'hibernation avec de nouvelles spécifications pour le printemps.
Lors des annonces de lundi, Apple nous a promis des processeurs Broadwell de nouvelle génération avec des cartes graphiques mises à jour, Thunderbolt 2 et une mémoire flash plus rapide. Rejoignez-nous alors que nous sautons sur le capot pour confirmer et voir si quelque chose a changé au cours des onze derniers mois.
Le MacBook Air 11" a également été mis à jour, nous sommes donc en double service de démontage. Découvrez l'Air 11" ici.

Outil utilisé dans cette étape :P5 Pentalobe Screwdriver Retina MacBook Pro and Air$11.99-
This newest 13" Air keeps its traditional model number, A1466. For identification purposes, you'll need your serial number, EMC (2925), or model year (2015).
-
The right side is fitted with an SDXC card slot, USB 3.0 port, and (all new!) Thunderbolt 2 port. As before, the opposite end hosts the MagSafe 2 power port, audio jack, and another USB 3.0 port. Also included are dual microphones, designed to diminish background noise.
-
Ahh, mine old nemesis Pentalobe.
-
We see Apple hasn't changed its stripes—the classic pentalobe keeps this Air sealed up from the common fixer.
-
Luckily, we have a handy driver for just these occasions. And... we're in!

One of these is the updated, Early 2015 MacBook Air, and the other hails from mid-2013. Can you tell which is which?
-
At first glance, neither can we. This MacBook plays its AirPort cards pretty close to the vest.
-
If you guessed wrong, fret not: we're about to get down to the nitty gritty.

Up next, our favorite Air feature: battery removal. Thanks to this tidy plastic frame, the battery is held in with five screws and no adhesive—easy for fixers, easy for recyclers.
-
The battery specs carry over as well: the Air continues to sport a 7.6 V, 54 Wh, 7150 mAh battery. Thanks to the new Broadwell chips, we're supposed to get more life out of the same capacity: Now up to 12 hours of web browsing or video playback.
-
For all you scorekeepers, that's 2 Wh and a theoretical 1 hour more than the new Dell XPS 13.

The flash memory is still PCIe-based, and remains, thankfully, removable—at least for now. Popping it out for inspection, we find:
-
Samsung S4LN058A01 PCIe 3.0 x4 AHCI flash controller
-
Samsung K4E4E324ED 512 MB LPDDR3 DRAM
-
8 x Samsung K9LDGY8S1D-XCK0 16 GB flash storage (128 GB total)
-
Apple tells us this bad boy "...features faster flash storage that is up to two times faster than the previous generation."

With the heavy bits removed, we catch the logic board before it floats away. Turning it over, we found the heart of the matter:
-
1.6 GHz Intel Core i5 5250U processor, with integrated Intel HD Graphics 6000
-
Intel DSL5520 Thunderbolt 2 controller
-
GL3219 Genesys Logic SDXC controller
-
LT3957 Linear Technologies inverting controller
-
In contrast, the integrated Intel HD Graphics 6000 brings a legit graphics performance boost (roughly a 20-25% improvement over HD 5000).

On the flip-side, the logic board packs:
-
SK Hynix H9CCNNN8JTALAR LPDDR3 SDRAM 4 x 1 GB for 4 GB total
-
Broadcom BCM15700A2, appears to be a multimedia controller
-
SK Hynix H5TC4G63CFR 4 Gb low power synchronous DRAM
-
Macronix MX25L6473E serial multi I/O 64 Mb flash memory
-
Texas Instruments TPS51980A synchronous buck controller
-
Texas Instruments/Stellaris LM4FS1EH SMC controller
-
Intersil 958 26AHRZ N450MT and SMSC EMC1704-2 Current/DC Power Sensor with Temperature Monitoring

Continuing the trend of sameness, the I/O board is nearly identical to the one found in the MacBook Air 13" Mid 2013, even down to the audio codec IC:
-
Cirrus Logic 4208-CRZ HD audio codec, likely similar to the 4207

MacBook Air 13" Early 2015 Repairability Score: 4 out of 10 (10 is easiest to repair).
-
Once you manage to take off the bottom cover, all the parts are pretty easily replaceable.
-
Proprietary screws on the case require the right screwdriver.
-
All the components—including RAM and SSD—are proprietary.
-
As with the prior iterations, this MacBook Air's biggest detractor is the lack of upgradeability. The RAM is still soldered to the logic board, and SSDs are not compatible between generations.

Question. What does this line mean: "SSDs are not compatible between generations."
What I want to know is if the hard drive is upgradeable or not.
The ssd is the harddrive, which according to the guide is removable but it is proprietary and is not available aftermarket so effectively not upgradeable.
