Introducción
Microsoft acaba de revelar un 2 en 1 para aquellos que están en movimiento, aquellos que desean un Surface con un poco menos de profesional y un poco más. Es posible que esta Surface tenga muchas ventajas, pero solo nos preocupa una cosa: ¿puede repararla mientras viaja o será detenida en su totalidad por baterías gastadas y pantallas destrozadas? Sólo hay una forma de averiguarlo: ¡listo, listo, desarmado!

Qué necesitas
Resumen del Video
-
-
Como siempre, nuestro desmontaje comienza con una breve introducción:
-
Pantalla IPS multitáctil de 10 "con relación de aspecto 3: 2 y resolución 1800 × 1200 (217 ppi)
-
Procesador Intel Pentium Gold 4415Y de doble núcleo a 1,6 GHz con Intel HD Graphics 615 integrado
-
4 GB de RAM (8 GB opcionales)
-
64 GB de almacenamiento eMMC (128 GB NVMe SSD opcional), con almacenamiento adicional a través de microSDXC
-
Cámara principal de 8 MP con video de 1080p; Cámara autofoto de 5 MP / 1080p
-
-
-
Comparado con el Pro, el Go parece tener curvas más suaves, bordes redondeados y una estética del iPad más vaga.
-
Surface Go no cree en la tendencia de menos puertos es más puertos. Esta tableta incluye un puerto USB-C, un conector para auriculares, un par de conectores patentados y un lector de tarjetas SD.
-
Mirando entre las bisagras ligeramente rediseñadas, observamos la información de la FCC, el número de modelo (1824) y las especificaciones de almacenamiento y memoria.
there are no magnetometers in the surface go…u probably pressed the power button when u tried opening the kickstand
-
-
-
Hay más de una forma de derribar. Nuestro camino toma un tiempo, así que nuestros amigos de Creative Electron nos dan la versión de rayos X.
-
Información preliminar: dos celdas de batería, una gran cantidad de circuitos, ¡y no hay tuberías de calor visibles! Parece que la Surface ha estado en una dieta baja en cobre.
-
-
-
Si hemos aprendido una cosa después de cinco años de salir la S, es cómo abrir estas cosas.
-
Nuestro bien usado iOpener brinda calor, luego un asa de succión y picos de apertura (solo unos pocos) atacan el amplio adhesivo.
-
La pantalla está apagada y nos complace ver que Microsoft le permitió una correa bastante larga.
-
-
-
Un último obstáculo antes de que la pantalla sea libre: un protector de garra EMI que protege el conector ZIF de la pantalla.
-
Con la pantalla libre, dirigimos nuestra atención hacia el borde inferior y descubrimos algunos chips de pantalla en su entorno natural:
-
Probable controlador de temporización LCD de la serie S15 de MegaChips
-
i7248 H717690
-
18996MB N746547
-
KTH6212MAYS
-
-
-
-
Para nuestra gran sorpresa, el Surface Go tiene una batería que se puede desconectar de inmediato. Sin necesidad de retirar completamente la placa base, la capacidad de reparación está mejorando.
-
¿O es eso? Quitar la batería es como en los viejos tiempos: dos almohadillas de adhesivo gigantesco luchan contra nuestro removedor de adhesivo y nuestras tarjetas de plástico.
-
La batería del Go es mucho más pequeña, con 26.12 Wh, que cualquiera de sus antecesores profesionales, incluso el iPad 6 de tamaño similar tiene un banco de energía de 32.9 Wh.
-
Un administrador de paquetes de baterías de iones de litio de la serie BQ40Z50 de Texas Instruments es el cerebro de esta operación.
-
-
-
Al centrar nuestra atención en las antenas de Wi-Fi, esperamos encontrarlas destrozadas después de la separación de la pantalla hack-and-slash.
-
Tener el cristal de la cubierta de la pantalla pegado sobre la parte superior de las antenas de Wi-Fi ha causado estragos en muchos intentos de reparación de Surface Pro. La mayoría de las veces, las antenas no sobreviven la eliminación de la pantalla.
-
Esta vez, tenemos que seguir mirando ... y mirando.
-
Estas antenas son realmente difíciles de detectar, y parecen milagrosamente intactas. Esa es una de nuestras pobres antenas Surface Pro de quinta generación en la parte superior, para comparación.
-
Definitivamente se han rediseñado, ¿quizás con una experiencia de reparación un poco menos mordaz?
-
-
-
Nuestro viaje bajo la Surfaceno se vuelve más fácil a medida que avanzamos hacia la placa base.
-
Afortunadamente no hay pegamento aquí, pero nos vemos obligados a excavar en nuestro camino a través de capas interminables de escudos, cintas y tornillos ocultos para desenterrar el tablero.
-
Finalmente, relevamos a la placa base de la última de sus restricciones y la liberamos de su prisión de metal y plástico.
-
Incluso con la placa base libre, seguimos cavando, a través de protectores y pegatinas de tela, para encontrar el silicio que se esconde debajo.
-
-
-
Por fin, somos recompensados por nuestro arduo trabajo con un tesoro de silicio:
-
Procesador Intel Pentium 4415Y
-
SK Hynix H26M74002HMR 64 GB eMMC5.1 memoria flash NAND
-
2x SK Hynix H9CCNNNBKTAL 16 Gb LPDDR3 SDRAM (4 GB en total)
-
Controlador de carga Buck-boost de la batería Texas Instruments BQ25700A
-
Controlador de fase ON Semiconductor NCP81216
-
Qualcomm QCA6174A Wi-Fi / Bluetooth SoC
-
Parade Technologies PS87430 (probable conmutador de host USB)
Is the hard drive removeable and if so what are the dimensions
-
-
-
Todo ese silicio, y sin embargo este Go no tiene ventiladores ni tubos de calor. Este delgado escudo de cobre y algo de pasta térmica tendrán que hacer el disipador de calor para esta posible PC. (Una vez más, siempre se puede ejecutar en un congelador ...)
-
Sin duda, es un alejamiento radical de esos gruesos tentáculos de cobre que encontramos en la 5ª generación Pro, a la derecha. Esperemos que sea suficiente para el procesador no Turbo'd del Go que consume energía.
-
Ahora para arrancar las cuerdas finales de este desmontaje. Tales como: la cámara Windows Hello, la cámara frontal de 5 MP y la cámara trasera de 8 MP (completa con LED a cuestas), todas en fila.
-
Finalmente, el puerto microSDXC modular con controlador de lector de tarjetas Realtek 5227S, que es un almacenamiento técnicamente actualizable.
-
-
-
Microsoft Surface Go obtiene 1 de cada 10 en nuestra escala de reparabilidad (10 es la más fácil de reparar):
-
El factor de forma más pequeño parece hacer que el vidrio sea más fácil de quitar sin romperse, pero sigue siendo terriblemente duro.
-
Si se espera que esto reemplace una PC, la falta de capacidad de actualización limitará severamente la vida útil del dispositivo.
-
La falta de modularidad, especialmente en puertos de alto desgaste, hace que las reparaciones sean innecesariamente costosas.
-
El adhesivo mantiene muchos componentes en su lugar, incluida la pantalla y la batería.
-
El reemplazo de cualquier parte requiere la remoción del ensamblaje de la pantalla, una parte fácil (y costosa) de dañar.

Do you think the Surface go 128gb uses a different motherboard? This 64gb model has the eMMC ssd chip, but I don’t know if there are any pin compatible nvme ssd single-chips packages that feature the same pcb footprint and signaling as an eMMC part. I’m pretty sure an NVME ssd has to have a separate controller and nand at this point in time. I have not seen any one-chip packages yet. Even the new MacBook Pro 15" Touch Bar 2018 teardown revealed a multi-package configuration (controller + 2 nand packages) for the integrated nvme ssd. It doesn’t look like there’s room for a m.2 nvme drive in the surface go either, so I think the 128gb/256gb model uses a different motherboard. Let me know what you think! :D
I looked into mainboard’s picture and found many blank area on the top left. Probably it was designed for SSD and will be used on 128GB model. I don’t think Microsoft will spent too much money to design and manufacture another type of mainboard.
Looks like the empty solder pads on the back of the main board between the USB-c and charge connector have space to solder a NVMe connector. May also need controller though as Al2Me6 mentioned on 08/04/2018. I would like to know if an NVMe drive can be added to the EMMc version I have.

I own this product and it is not that great. All you can do is search the internet and its so slow, my phone works faster! I had to re-install windows 10 Pro just to get some speed out of the unit that ships in windows 10 S mode, The S is for slow lol… The S is for secure and locked down to windows store apps, which is not much. You can opt out of S-Mode but then you get windows 10 Home. you can not even CMD or run a simple bash command in S mode. Expect a ton of returns from uneducated general public. There is no fan, but there is no vent, the back becomes extremely hot. the 9 hour battery life must have been conduced by someone who does not know how to tell time or possibly the “watchman” cause I’ve had a number of test and im getting around 3 hours.
There is no reason for the 4GB 64GB $399 table to exist, Windows is around 30GB storage after all updates needed. Its a shame that truly for a okay slow Surface is $760 with a keyboard after tax for the 8GB configuration.
My keyboard stopped working, it bent.
I agree that on Windows 10, as with all reviewers, this product is pretty much useless. That said, for me, it is incredibly useful only because, as a few other people have done, I wiped the drive of Windows and installed Linux (Ubuntu). This gets around all of the performance issues and it works great for general programming tasks and even low-end gaming.
I agree I would really like to see what the SSD motherboard looks like, I imagine that the SSD is still soldered to the board, but I wonder what controller it uses.
I believe this is the SSD used https://business.toshiba-memory.com/cont...

Why is the logic board so large? For such a simple machine, this logic board is far too large. Compare to the MacBook 12, or even the Surface Pro logic board they have beside it. Above and to the left of the CPU are vacant pads for several large BGA chips-this is far too much space for a LTE modem or a PCIe SSD as found on the higher end models. I wonder what Microsoft has planned.
I would imagine that the empty solder pads are for the optional NAND SSD and controller.

Fantastic device! Of course, the Apple sheeple will hate on it automatically, hence some of the comments above. It’s an amazing, low cost, portable, full-fledged PC that you can take anywhere. This is coming from a 20+ yr Mac user, as well (I use both Macs and PC’s and know them well.) Def get the 8 gb configuration. I’ve been using mine nonstop for 2 days and it’s not slow at all. I’m getting around 7-8 hrs battery life (the device also fast charges fully within an hour via surface connect), screen brightness on medium. Keyboard is strong, keys have TRAVEL (something Macs don’t have anymore) and it’s sturdy and premium quality. (Go check one out at your local MS store or a Best Buy before buying.) Reparability is non existent these days, so a 1 or a 0 is fine with me. What did the last gen MacBook Pros get, a 1 or 2 as well? I generally (like everyone else I know) tend to upgrade their devices 2-3 few years, anyhow. The Surface Go is perfect for me. Thanks for the tear down!
there’s no way this is better value then Samsungs windows tablets. For the same price you get a fast ssd, AMOLED display and a core M cpu. Plus it looks better and has a better battery life.
Arthur Dent.. That’s your opinion, and thankfully, everyone’s got one. I’m very satisfied with my Surface Go. (I have a Surface Book 2 when I really need to do major productivity.) Samsung Windows tablets don’t have Surface Pen compatibility and I think this is a much better value, seeing as it works seamlessly with all my other Surface devices. This is just literally for ‘on the go’ and it’s an amazing device in my opinion. The Samsung Galaxy is $727.99 at WalMart, a little out of my price range for a secondary device, imho. I paid around $600 for my Surface Go with the Alcantara cobalt blue type cover, using one of my other Surface Pens and Mouse.
And here’s my opinion. Every device needs some form of repair at some point to keep the price down of buying new hardware every 2 years. Who wants to spend $400-$600 every 2 years.
I work in a repair shop, and I stay away from all Surfaces now. I just had a customer call me 20 minutes ago asking if I repair Surface Go’s. I said “no, too much can break just opening them up”. After the call I researched what a “Surface Go” is. Now I’m glad I didn’t take on that challenge.
Repairability of 1? I’d never buy one, and I feel sorry for the suckers who have and end up with a broken one seeking for repairs. At least they don’t put the WiFi and Bluetooth antenna under the adhesive anymore.
iPad Pro 12.9” scored 3, iPad Pro 10.5" scored 2, iPad Pro 9.7" scored 2 even iPad Mini 4 scored 2…. why this is not al least 2 then?
because, it seems, iFixit is funded, run or somewhat biased towards Apple and its products, I’ve never seen a real teardown where Apple is treated like the rest it is alwys in the line “it uses mild adhesive for the sake of lines and design” or “look, is propietary but,, hey it’s apple” things like that

The Surface line is meant to be a personal computer, while iPads are mobile devices, so the comparison should really be Surface to MacBook, and those devices score very similarly. Apple notebooks are consistently at the [http://Apple does a pretty good job prioritizing screen and battery replacements in their tablets and phones, |bottom of our repairability lists]. Apple does a comparatively good job prioritizing screen and battery replacements in their tablets and phones, and our scores reflect that.
Apple devices should get higher scores because of the 3rd party parts that are widely available. With Apple you get your choice of vendors. Only issue with Apple parts is deciding which vendors to buy from.
“Microsoft Surface Go is a repairability nightmare … “, writes Brian Fagioli in Betanews.
The hardware creators are always balancing many competing & contradictory factors. Apple is THE most hostile, against the end-users, and against maintenance-repairs. IFIXIT is famous for explaining these criminal actions of Apple products.
I'm surprised that it has the lowest repair-ability rating.
> "Surface Go has an immediately disconnectable battery!”
Rechargable batteries are not yet designed to last beyond a few years.
> "Thankfully there's no glue here”
There have always been alternatives to most forms of "glue" (plastic-melding, etc).
Buyers of these hardware items need to be able to instantly repair their products instantly the need to repair is needed. Users do not actually live inside the home of expert maintenance engineers, believe it or not. Often the "repair" might be just be to remove drops of water or other fluids.
We need to push for a law that ALL devices should be serviceable, and all batteries (and other toxic items) should be removable to be recycled; how hard could it be to have a removable back panel? I fear these will be going into landfill with their batteries inside in a few years.
Buy products that have high repairablity scores and you reward those companies. Most consumers prefer cheap to better. Don’t drive up prices on cheap products because they don’t meet YOUR needs.
You negative “lifespan”, which has nothing to do with repair ability. A little journalistic integrity would go a long way here…
The complete sentence reads, “If this is expected to replace a PC, the lack of upgradability will severely limit the device's lifespan.” Repairability and upgradability are both about the same thing: extending the device’s lifespan. Always has been.
Some interesting engineering for the heat-pipes. They avoid the bottom left of the device, where most right-handed people would hold the device with their left hand. Cool. Literally.
You forgot to mention USB chips. Realtek RTS5452, USB controller i think, but didn’t find a datasheet for it. Parade technology USB host switch https://www.paradetech.com/products/ps87... this chip reveal docking capabilities of the tablet: USB 3.1 Gen 1 with data rate of 5Gbps, and VESA DisplayPort Alt Mode with data rates up to 5.4Gbps (HBR2).
I wish someone would invent a new way to put together these slate form devices to make them user repairable/upgradable.
A few companies actually do make pretty repairable tablets. Most notably, HP makes their tablets to be very serviceable, and have publicly-available service manuals. If you’d like to see our repair reviews of a variety of tablets, check out our tablet repairability page.
Anyone know where to buy a replacement screen from? Cant find them listed anywhere!
FYI, based on the Surface Go driver package’s contents, it looks like the Surface Go’s mysterious “NXP P3003” chip is actually a NXP PN578 or NXP PN577. The “Drivers/NFC” directory has a pair of .DAT files that look like they’re firmware and the INF references them with some handy comments.
HKR,FirmwareMap,"8",0x00020000,"%%SystemRoot%%\System32\NXPPN547FW.dat" ; HW version of PN547 is 8
HKR,FirmwareMap,"10",0x00020000,"%%SystemRoot%%\System32\NXPPN548FW.dat" ; HW version of PN548 is 10
In the firmware’s ACPI tables, the chip is referred to as “NXP3001” and it looks like other vendors that implement this same family of chips use identifiers like “NXP3003”, “NXP3001”, "P3003”, “P1001”, etc. Given that info, the “P3003” identifier could be related to this pattern, or it could just reflect packaging or deeper customization of the chip being used in Surface Go.
Hopefully this helps anyone else who lands here looking for details on Surface Go NFC.
