Introduction

Tick, tock—that’s the sound of Intel punching out another line of processors, the newly minted Broadwell series. They splashed down into Apple’s MacBook Air lineup just yesterday, and we wasted no time in picking them apart. With the 13” model duly dispatched, we turn our attention to its 11” counterpart. Join us in tearing down the Early 2015 MacBook Air 11".

Breathe that heady teardown air—follow us on Instagram, Twitter, and Facebook!

This teardown is not a repair guide. To repair your MacBook Air 11" Early 2015, use our service manual.

What to expect from the Early 2015 MacBook Air 11"? We gave it a good looking over, but durned if we could tell it apart from the previous generation. Here's what the box says: 5th generation, dual-core Intel Core i5 processor with Intel HD Graphics 6000

Before we dispatch the back case, we take a quick peek at the model number, A1465—the same digits we found on models dating as far back as mid 2012. We've got a few loose screws—and we're proud of it!

    • We are proud that we're not getting screwed by any fastener, least of all Apple's proprietary pundit of prostration, the perfidious Pentalobe.

Our first look under the hood reveals exactly what we expected. Four hands. Or rather, no change from last year.

Black Friday
Broken doesn't stand a chance.
All hands on deck! Spudgers at the ready! Disconnect battery! That was easy. Removal was easy too, thanks to screws and no adhesive to get in the way of battery freedom. Let's see what this pack is packing: While the 7.6 V, 5100 mAh (38.75 Whr) battery matches last year's model spec for spec, Apple alleges an extra hour of life while watching iTunes movies (up to 10).

      • This is most likely attributable to improvements in the new Broadwell CPU.

  • Microsoft promises a similar "9 hours of web browsing" from its MacBook Air killer, the Surface Pro 3. The Surface has a slightly larger 7.6 V, 5380 mAh (42.4 Whr) battery.

While the bigger, badder, 13-incher Air got a faster and flashier SSD, the 11" model is stuck in 2013 with the same old, same old. Apple decides not to spread the upgrade fun; we get stuck with a geriatric, 2-year-old SSD. Bring on the extra help to get it up and out of bed. With a little poking and prodding, it proceeds to spill the beans—er, chips. In fact, they're very much the same chips we dipped into on the mid-2013 version:

Greedy for more chips, we decide to give the logic board the clamps. What's our reward? Let's take a look-see: 1.6 GHz Intel Core i5 5250U processor, with integrated Intel HD Graphics 6000

    • Intel DSL5520 Thunderbolt 2 controller

    • Texas Instruments 58873D synchronous buck NexFET power block MOSFET pair

    • ON Semiconductor 4902F RBV1L dual N-channel power MOSFET

  • Although Broadwell is mainly a 14 nm die shrink of the existing Haswell microarchitecture, it is up to 30% more power efficient.

We are airing the differences in these lightweight notebooks, and the last thing to come to the table is the I/O board. With a light touch, we remove the I/O board for a better look at the headphone jack, a USB port, and the MagSafe 2 port. A passing glance at the board reveals the same Cirrus Logic 4208-CRZ HD audio codec found in this year's 13" model (likely similar to the 4207).

MacBook Air 11" Early 2015 Repairability Score: 4 out of 10 (10 is easiest to repair). Once you get past the outer case, all the major components are fairly easy to access for replacement.
  • MacBook Air 11" Early 2015 Repairability Score: 4 out of 10 (10 is easiest to repair).

    • Once you get past the outer case, all the major components are fairly easy to access for replacement.

    • The outer case is held on with Apple's proprietary Pentalobe screws, so you'll need the right screwdriver to get inside.

    • Just like the screws, all the components—including the RAM and SSD—are proprietary, making replacement parts more difficult to source.

    • Worst of all, this MacBook Air is not upgradeable after purchase. Like many generations of the Air, the RAM is soldered to the logic board, and SSDs are not compatible between generations.

can you upgrade the ssd?

Can the SSD and RAM be upgraded? If not, what's the best thing to do if you want more storage and more RAM? Get a whole new MacBook?

Can i put a 1TB SSD in it?

robbie fetters - Reply

This is the answer to Conrado Pinto's question. As mentioned in the guide, the RAM is soldered to the logic board so you can't upgrade it.

Does it have liquid indicators.

Timothy Shek that guy's question is whether the ssd is upgradable not the RAM.
