我们很好奇,有没有人已经厌倦了苹果的设备?现在该去咬一口多汁可口的“微软水果”——Surface Pro 4,看看它葫芦里都卖的什么药了。从主观的角度上说,我们很希望微软想想在过去的一年间都做了什么,然后选择生产一台更完善的腿上平板(笔记本的laptop+平板的tablet相结合嘛,对吧,嗯?)。只有一种方法能让我们看清它的内部……好吧,其实是两种,因为我们还有X光版。那么,开始我们的拆解时间吧!

  • 乍一眼看上去,Surface Pro 4的传感器阵列比它的前辈更先进一些。

    • 我们发现它至少有4个开孔。一个是摄像头,另一个也许是麦克风,但剩下的是啥?

  • 在新款Surface设备的背面,我们发现了熟悉的一排圆形——8百万像素后置摄像头,旁边并列放置一个状态指示灯和麦克风。

  • 各位同学是否急于一窥摄像头阵列的真面目,而又懒得拆机?那我们用X光照一下吧。


  • 这是个我们不经常见到的玩意儿——润滑脂!Pro 4外露的铰链都涂上了润滑脂,以满足各位不同的场景需求。

    • 只是各位要注意,别把线头,宠物毛发或者沙子啥的弄进里面去……

  • 要使得支架能够展开如此大的角度,还要拥有足够的阻力以支撑起平板,微软的工程师也许在这套铰链上面花费了大量的时间精力。所以,我们还是用X光照照它们。

  • 即便是在Surface Pro 3痛苦的拆解之后,恐怖的粘合依旧困扰着我们的拆解工程师。因此今年我们做好了最坏的打算。

  • 战场的开端,是由iOpener带领的,我们利用它来软化屏幕的胶水。

  • 我们的iSclack也加入了战斗,为的是提供足够的拉力,让我们能进一步深入敌后。

  • 小样,即便你叫Pro,也是不能把我们挡在门外的。在我们把opening pick塞进屏幕底部边缘后,拉锯战正式结束。

    • 我们还特别侧耳倾听了是否有玻璃碎裂的声音,但似乎我们只要按照这个方法拆解,就能很幸运地避免碎屏!

Is the iOpener now the preferred tool for opening up Surface devices? Because over at the Surface Pro 3 guides, iFixit mentions that a heat gun would be better. Also, how many iOpener passes does it take for the adhesive to melt and the screen to lift easily like that?

allanwl - 回复

The new iOpener is able to get hotter, sty hotter, and make more contact with the surface (no pun intended) so we'd use it for guides instead of a heat gun. The amount of time it will take to soften the adhesive will vary depending on ambient temperature, the temperature of the table you're working on, etc. The best method is going slow and steady, stop any time you feel resistance. It certainly took us a long time to get into our teardown device. If you need more advice, check out our Answers forum to consult people who may have tried heat guns or other methods!

Sam Lionheart -

Watch out for the WiFi Antennas when prying off the screen at the top! They're just thin strips of copper sandwiched between two sheets of plastic. Pictures from Step 10 below shows them as greenish-yellow traces on both sides of the camera assembly near the text that says "Supplier name: FIT"

They are very easily nicked if you're using a metal prying tool, and you might accidentally tear them when pulling up the adhesive tape.

  • 哟,这下发现新东西了。在上一次 我们拆解Surface Pro时,我们碰到了一个由弹性金属支架覆盖的显示屏排线。

  • 这回,它就变成了两根排线链接显示屏本身,使得屏幕不能再像一本书一样任意打开了。唯一的解决办法就是:把排线拔下来。

  • 当然了,微软已经改过这些排线端子的设计。显示屏排线端子相对来说更像常规的按压式设计——与iPhone的显示屏类似——但不同的是它们被金属罩所覆盖。

    • 幸运的是,我们只需要对第一个排线端子动动手脚,然后屏幕就差不多能拿出来了!


  • 虽然它并不是什么贺卡,但显示屏背面还是印有一些让人看起来很认真负责的条码。

    • 这或许也是值得高兴的事!比如说,这代表着品控的提高。

  • 出于好奇,顺便为了装个B,我们量了量面板玻璃的厚度。只有0.4毫米。这仅有4根人类头发的厚度(真的不是小米笔记本那样的比较方法),而且我们竟然没弄坏它。*此处应有掌声*

  • 接下来,该尝一尝我们最喜欢的硅晶点心——芯片了!其中包含了几个N-trig IC,应该是用来为Surface Pen提供硬件支持的。

Suppose someone with access to a laser cutter wanted to cut an opening in back cover to upgrade the SSD. Would that component be as freely accessible as it appears in photo Pro4_28.jpg? Or is there some other material or insulation between the back cover material and that layer of components? Ideally, an access opening would be covered by the kickstand plate, but it appears as though the socket for the SSD might be just under the upper half of the back cover, requiring cutting into the upper half of the back cover as well. Or would there be just enough clearance to angle the SSD chip into its socket?

Greg - 回复

I would imagine that the motherboard being in the way of the SSD is an issue. The other problem would be setting the laser cutter in such a way that you would not cut a massive hole through the entire unit.

Sam Lionheart, thank you so much for replying to my concerns abou the iOpener and the screen. However I only asked about how many passes it took because I have to do the inverse. I need the adhesive soft enough so it adheres back to the screen again, so I won't find resistance to know when it's worm enough/already cool. All I'm going to do is put some weight over it. Would say that 1 pass would be enough to heat the adhesive enough on only one edge of the screen?

allanwl - 回复

Ah I see! That makes it a little different then ;) I would say a couple passes on each edge (of two minutes or so maybe) would be good. You want the device to be fairly hot to the touch before you weight it down. After the device has fully cooled, you should poke at it a bit to see if the seal is complete. If it's a little loose, you may need to open it, remove the adhesive, and apply new adhesive. Good luck!

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.

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!

Alex - 回复


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!).

ddink - 回复

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...

Andrew Optimus Goldberg -

Thank you for your response. The diffusion to the battery is what I am scared of. Doesn't it reduce the lifetime of the battery (that's why I asked for the thermal insulation)? I'm just curious how they manage, that the battery never reaches the 140*F they have written on it. Maybe we'll see when someone makes a heatmap of the device ;).

ddink -

It looks to me like the heat is mostly going to the battery... I wonder why they couldn't have added at least a heatsink to the second heatpipe so it at least does something?

Larry Chen -

As for the heat-plate, what about the back of the LCD display? The back of the LCD is a large sheet of aluminum. I bet that most of the heat form the heat-plate is transferred to the display, thus spread throughout the entire machine.

Philip Hanner -

The heat appears to dump into the battery pack. I recently had the left battery cell expand enough to force the screen off of the surface along the left side. A good 1/4 inch separation

timothygill -

This is also my concern (I have i7-8GB).

Instead of using the back magnesium they are bringing the heat to the temp sensitive regions of this device!!!

Mohammadreza Najafi -

So it appears that the Micro-SD port is UHS-I only, not UHS-II, correct? UHS-II chips have 16 pins, but the x-ray appears to only show 8 pins, which is standard for UHS-I. I couldn't find anything about the Micro-SD RealTek controller.

Thinking of replacing the SSD with a larger capacity model (since Microsoft charges an arm and a leg for extra space). But if I open the device by softening the glue with an iOpener and using an iSclack, how do I re-assemble/re-glue the device after putting in a new SSD?

John Doe - 回复

This is the question no one seems to answer. My Pro 4 froze and on reboot the SSD has disappeared. I was able to boot into a live Linux install and it doesn't see the OS drive, nor does the Windows reinstallation tool.

as well as this: https://www.amazon.com/NIUTOP-Double-Adh...

but not entirely sure how wide to get it?

Anthony Raynor -

It would seem like this design would cause the battery to heat up considerably, which I can't imagine being too good for it. Considering how how these things get, it would appear that this would only cause the battery to have a shorter lifetime and make a difficult replacement come sooner.

If this is not a troll question, don't attempt this yourself. You have much to learn before attempting to replace SSDs on a screw-less device. I suggest building your own tower PC first. There is only one permanent storage drive on this device, so Windows will necessarily be installed on there.

To more clearly answer your question, you could either attempt an image level copy of the drive or yes, reinstall windows.

workingshane - 回复

Return and buy OEM, always oem even if you have to charge more. It install better confidence in your tech's on quotes and makes repairs a breeze and less likely for defects. Every OEM screen I have ordered came with the connectors and pcb's attached. Just because it's cheaper and margins are better doesn't mean a "good" repair. But you can lift it off carefully, make sure you photograph everything as not perfectly lined up and exact could and most likely will cause clearance issue and possible ribbon folding/tearing from that clearance. All because the adhesive you most likely have was not spec'ed or QA'd with the device, that's extra milimeters that wasn't intended for. All and all being creative and doing these steps wastes more time and could end badly rather than ordering the screen with it. If anything you have a spare cracked screen to practice perfection on removing it.

mike griffin -

Hi! the ntrig board is glued with double sided tape on the LCD and it is fairly simple to remove. The same tape is sticky enough to hold the pcb on the new screen. Just be careful with the ribbon cables, they are very frail. (the ones on the broken screen that I replaced broke in the middle of the bend as soon as I disconnected them).

Dietmar - 回复

With a little heat as you scrape carefully will get it off very nicely. Use a soft cloth with MGchemicals 99% isopropyl to clean off what a plastic spudger and slight heat couldnt, and the isopropyl will give a better clean surface to adhere new adhesive. If you have to use metallic objects to scrape clean try not to dig into the aluminum, while it won't show after repair, it will cause "pits" & "craters" (under the scope you can see em!) and will not let your adhesive have "bite" on the aluminum side and potentially leaves you open for a return or redo because of lifting.

Yes I agree with your scoring on these, I've repaired many surfaces and all are pain in the rear side, kind of. I wish I could find that foam-type adhesive used, that stuff is really strong.

You'll have your work cut out for you as not only is it rough to open your potentially gambling with $2k worth of MSRP hardware!

chassis for i3 and i7 models have different thickness. i7 has a fan that the i3 does not. it's highly unlikely you would get it to fit the way you described.

Has anyone been successful in finding the schematics for this board? I have a water damaged Surface Pro 4 I'm working on and trying to find replacement ics and bga chips to replace.

Thank you

It'll be easier to replace the entire board than try to replace individual ICs.

Helllo everyone, I am ina bit of a mess with this device. I tried a screen replacement on my i7 pro. Whilst doing this I mistakenly tore the flex that connects the n-trig board to the motherboard. But I still tried to connect all together to at least check that the display I bought is working.

Unfortunately I didnt get any thiong on the screen, I have now ordered a new flex ribbon whic h should hopefully be here on Friday. Does anyone know if this could be responsible for my no display. I am sure the pro is on as I can feel the board is warm etc. I've also ordered an HDMi which I can hopefully use to see it on an external screen. Has anyone here attempted a screen replacement before?

Can you changed a CMOS battery in SP4 to get out of UEFI stuck mode since I do not have the password?

Any idea how to remove the CMOS battery and replace, or does this not exist on the SP4? thanks

Can you remove and replace the CMOS battery on a SP4? Or does this not exist? How did you get around the stuck UEFI mode? thanks

Ian -

If we want to reset the CMOS/BIOS we can just remove the battery connector, correct ?

To re assemble the LCD is there a specific glue or just double side tape? And what is the replacement SSD (512) type or model number?

Hi. What’s the red surface just behind the CPU, non-conductive insulation? Also, what type of adhesive material is used at the back of the batteries? It there any chance that the batteries also serve the role of heat pipes, transferring heat they absorb from the copper plate to the back panel, via the adhesive? That would explain how the back of the Surface Pro feels warmer than the touch screen (that’s my impression).

I didn’t see the antenna for the wifi thingy…actually, did we even see the wifi chip in this teardown???

Well, the antenna is clearly visible in the last pictures of this teardown, when they hang around loosely around the empty frame.


Overall it was a decent *laptop* that was repair-wise ACCEPTABLE, with screws, still, holding most things down.

That array of connectors for keyboard and stuff should add point to the score of 2.

Overall, it shouldn’t get a 2. Yes, you can’t get the battery out of there without destroying it (or practically burning it so it will be hot and soften the glue), but when you do need to get the battery out there it is pretty much dead, so you can just wrestle it out, and put LIGHT ADHESIVE (opposite of Samsung’s patches) for convenience.

Personally, I’d rate it 6. Because only the display was lagging off.

I hate those new, adhesive-bound new “thin“ models. I think a 0.5 inch thick “brick” would be better.

Although, one had hever made a great touchscreen held with screws…
