Introduction

Microsoft hardware is having a little bit of an identity crisis. Microsoft calls this new Surface Pro "the most versatile laptop", which means that this tablet is actually a laptop (that can transform into a studio surface). Tell ya what Microsoft, we are going to reach deep inside and see if we can't help. Friends, we present to you the Surface Pro 5 self-discovery teardown!

We want to help all Microsoft devices figure out what they are made of. You can view our Surface Laptop teardown here!

This teardown is not a repair guide. To repair your Microsoft Surface Pro 5, use our service manual.

  • From the outside, this Surface Pro looks pretty similar to last year's model. But you know what they say, it's what's on the inside that matters:

    • 12.3” IPS PixelSense Display with 2736 × 1824 resolution (267 PPI)

    • Intel Kaby Lake Core m3 (4M Cache, 2.70 GHz) up to Core i7 (4M Cache, 4.00 GHz) CPU

    • 4 GB/8 GB/16 GB 1600 MHz DDR3L RAM

    • 128 GB/256 GB/512 GB/1 TB of solid state storage

    • 8 MP rear-facing 1080p camera, and 5 MP front-facing 1080p Windows Hello camera

    • USB 3.0 port, micro-SD slot, Mini DisplayPort, and SurfaceConnect charging port

    • 802.11a/b/g/n/ac Wi-Fi, Bluetooth 4.1

  • Stacked on top of its elder sibling, the 5th gen Pro looks very nearly identical. It has the exact same ports in the exact same places, and features the same physical dimensions.

  • With such a similar exterior, it's no surprise that we find an identical opening procedure. Just as in the Surface Pro 4, we apply some iOpener heat, suction up the display, and slice through the adhesive with an opening pick.

  • We start looking for differences and pick out a whopper—Microsoft has traded away the removable blade SSD for a little more battery real estate. There goes the sole upgradeable feature from last year's model.

    • Additional, less-exciting differences include a more spidery heat sink design, four-cell instead of two-cell battery, and svelte new black color scheme.

  • The back of the display houses a number of chips that look suspiciously similar to the N-trig modules found in the Surface Pro 4:

    • Microsoft X904169 06 CL1714

    • Microsoft X904163 01 CL1715

    • Macronix MX25U1635F 1.8V 16 Mb MXSMIO serial flash memory

  • Microsoft acquired N-trig in 2015. Looks like they've finally fully integrated their tech, slapping a Microsoft label on the chips.

  • Microsoft claims to have wholly redesigned the passive cooling, to allow both the Core m3 and Core i5 models to run 100% fanless, instead of just the m3 model like last year.

  • Now that the motherboard is out, let's have some chips.

    • Intel Core m3-7Y30 Processor

    • Samsung KUS020203M-B000 NAND flash memory

    • Samsung K4E8E324EB 1 GB LPDDR3 1866 MHz DRAM (4 chips for 4 GB total)

    • Marvell Avastar 88W8897 802.11ac, NFC and Bluetooth SoC

    • Nuvoton NPCT650SBBWX TPM IC

    • Winbond W25Q128FV 128M-bit Serial Flash Memory

    • Monolithic Power Systems MPS1708 and MPSG53

SAMSUNG KUS020203M-B000 should be NVMe SSD in BGA package, not NAND Flash chip.

What is the Winbond W25Q128FV for?

Image 1/1: So, we're gonna keep it glued in today...
  • If we learned anything from the last Surface Pro we tore down, it's that the battery is a pain to remove, and it doesn't go back in quite the same.

    • So, we're gonna keep it glued in today...

  • This four-cell LiPo measures in at 45 Wh (7.57 V x 5940 mAh). That's a nearly 18% increase in battery capacity (and 100% increase in cell count) over the previous model.

    • To compare Apples to Apples Surfaces, the 10.5" iPad Pro we tore down last week sports a 30.8 Wh battery.

  • Psst—hey, wanna take a peek at the Core i7 Surface Pro? Thanks to Creative Electron, we got the goods.

    • Not much difference between the models, but that mysterious empty space under the heat sink is indeed filled with extra cooling power in the form of a fan.

Final Thoughts
  • Although we like connectors, the ones present in the Surface Pro aren't standard, making display removal tricky.
  • The display removal procedure is simplified by the use of thin foam adhesive and a fused display, but is still not trivial.
  • Adhesive holds many components in place, including the display and battery.
  • Replacement of any part requires removal of the display assembly, an easy part to damage.
  • The SSD is no longer replaceable.

You forgot to document the micro SD card reader controller and a few other less notable members of the entourage of chips. Is it still the Realtek one, the RTS5304, from the Surface Pro 4? I am curious as to if they improved that aspect at all as well.

it should be Realtek RTS5343

Thanks for the New Hope Trench distraction :-)
