With the top-of-the-line model coming in at over $2600, the Surface Pro 4 had better be a cut above the rest—the spec sheet looks promising so far:
-
12.3" PixelSense 2736 × 1824 (267 ppi) IPS LCD display
-
Intel Skylake Core m3 (4M Cache, 2.20 GHz) up to Core i7 (8M Cache, 3.80 GHz) CPU
-
4 GB/8 GB/16 GB DDR3L 1600 MHz RAM
-
128 GB/256 GB/512 GB/1 TB of PCIe solid state storage
-
8 MP rear-facing 1080p camera, and 5 MP front-facing camera
-
USB 3.0 port, micro-SD slot, mini DisplayPort, and SurfaceConnect charging port
-
802.11a/b/g/n/ac Dual Band Wi-Fi and Bluetooth 4.0

At first glance, the Surface Pro 4 appears to outshine its predecessors with its forward sensor array.
-
We spy at least four nodes of interest. One's a camera, one's probably a microphone, but the rest?
-
On the rear of the new Surface, we find a familiar arrangement of circles—the 8 MP rear-facing camera accompanied by a status LED and microphone.
-
Anxious to see the camera array but too impatient to open the device? X-ray it.

That's something we don't see too often—grease! The Pro 4's exposed kickstand hinges are lubricated to meet your transforming computational needs.
-
Just try not to get any lint, or pet hair, or sand in there...
-
To get such a wide spread of kickstand angles, with the resistance required to support the tablet's weight, Microsoft's engineers probably spent a lot of time on these hinges. So we X-rayed them.

Les cauchemars collants hantent toujours nos ingénieurs de démontage après le déchirant démontage de la Surface Pro 3. Cette année, nous nous sommes donc préparés au pire.
-
Les choses commencent à chauffer dans la salle de démontage alors que l'iOpener se bat pour affaiblir l'adhésif de l'écran.
-
Notre iSclack se joint à la lutte pour nous fournir l'effet de levier dont nous avons besoin pour faire notre entrée, et osons le dire, les choses semblent plus faciles qu'auparavant.
-
Même un Pro ne peut pas nous faire reculer. Nous insérons un médiateur sous le bord de l'écran, c'est parti pour les courses!

Well, these are new. The last time we tore down a Surface Pro, we encountered a display connector trapped beneath a springy metal bracket.
-
This time around, there are two cables holding the display to the body, preventing it from being opened like a book on any hinge. Our only recourse: tackle those connectors.
-
And of course, Microsoft has modified their connector design. The display connectors are relatively common press-on connectors—similar to an iPhone display—but they're trapped under snap-on metal shields.
-
-
-
Ce n'est pas exactement une carte de vœux, mais le dessous de l'écran est orné de codes-barres qui semblent sincères.
-
C'est peut-être un message de félicitations ! On plus probablement la preuve de quelques intenses contrôles de qualité.
-
Il est temps pour notre collation à base de silicium préférée: les chips! Parmi eux, un certain nombre de circuits intégrés N-trig , probablement du matériel de contrôle pour le Surface Pen.

N-trig DS-D5000 A1

Turning our attention to the rest of the Pro 4, we spy a suspicious blank space beside the motherboard (and heat sink tubing!).
-
The motherboard is so close, yet so far. Unable to wait, we skip to dessert and pop off some shields to get a closer look.
-
The rest of the motherboard is nestled too snugly to investigate, but that SSD looks ripe for the picking...

Oh Surface, look how you've grown!
-
The Surface 4's Samsung branded SSD is considerably larger than the little whipper snapper we saw in the previous generation.
-
Awww, they brought us more chips. The 128 GB Samsung PM951 SSD is packing the following:
-
Samsung S4LN058A01-8030 PCIe 3.0 x4 NVMe flash controller
-
Samsung K9CHGY8S5C-CCK0 64 GB NAND flash
-
Samsung K4E4E324EE-SGCF 4 Gb (512 MB) DRAM
-
Texas Instruments TPS22966 5.5V, 6A, 16mΩ, 2-channel load switch
-
Silergy power management (likely)

Le dissipateur thermique de la Surface Pro 4 montre sa métamorphose impressionnante, affichant des caloducs en cuivre plus longs et une grande plaque de cuivre pour une dissipation de chaleur plus efficace.
-
Conçue avec un système de refroidissement hybride, la Pro 4 tire parti du refroidissement passif et actif.

Fittingly, the Surface has a pro line-up of cameras and sensors:
-
Infrared emitter
-
Infrared camera
-
Front-facing camera
-
"Privacy light" indicator LED (mounted on the rear-facing camera)
-
Microphone

We tweeze out the two stereo speakers from the corners of the case and make an interesting discovery...
-
The Good: These integrated buttons are much less fidgity to replace as one piece than each button individually.
-
The Bad: The entire speaker will have to be replaced to replace one of the buttons, increasing the cost of repair.

This 38.2 Wh, 7.5 V battery is rated at 5087 mAh—a 9 percent decrease from the 5547 mAh battery in the Surface Pro 3.
-
Despite the smaller battery capacity, the 4 generally outperforms the 3 in terms of battery life.
-
Just to compare Apples to oranges, the iPad Air 2 weighs in with a 27.62 Wh battery, however the upcoming iPad Pro is probably a more apt comparison, function-wise. We'll have to wait and see!

Microsoft Surface Pro 4 Repairability Score: 2 out of 10 (10 is easiest to repair).
-
The SSD is replaceable.
-
The battery is not soldered to the motherboard, but very strong adhesive makes removal and replacement a hazardous chore.
-
Non-standard connectors make for tricky display removal.
-
The display removal procedure, while difficult, and required for any repair, is not as hard as in previous generations, due to less stubborn adhesive.
-
The display assembly consists of a fused glass panel and LCD, and is difficult to remove and replace.
-
Adhesive holds many components in place, including the display and battery.

Looks great, much better than last year's. Pity about the glue for the screen. Would love to see screws. Know it's hard, because these are miracles of engineering, but there are lots of very smart men and women working on this, I'm sure they could find a way, especially since these are billed as enterprise devices, and having worked in an IT department, devices get broken a lot. No pen teardown? I'd imagine it's super similar to last year.
I want one of these even more now. Can't wait to see the Surface Book, if they managed to get one.
Thanks everyone at iFixit, keep up the good work. You're an inspiration to us all.
Is the set of huge connectors on the back of the motherboard in step 14 where the battery connects? They look too large for anything else.
Glad you liked it! They're tough to get ahold of, but we're definitely gunning for a Surface Book as soon as we can! Those are spring contacts on the reverse of the motherboard, that press against the battery cable and also the keyboard dock connector cable. I updated step 14 to mark them up and explain that, thanks for the reminder!
Hi,
I am curious about the copper plate over the battery. Is there some insulation against heat radiation to the battery? Does the plate radiate against the lcd (the battery also tells that the temperatures should not be higher then 140°F. Thinking about how they manage this)?
Thank you for the nice teardown (and fast!).
Hi ddink! The flat plate does diffuse heat into the battery and LCD plate. It actually works as one of two condensers that make up the hybrid cooling system. This article shows a bit more about how that works: http://www.techspot.com/news/62361-surfa...
