We have disassembled the Surface Pro 4 a few days ago, and we have some understanding of the internal structure of the new generation Sophie 4. Although the Surface Pro 4 has represented the latest technology of Microsoft, what is more interesting is the Surface Book equipped with an independent graphics card, which is inserted into such a small machine. The computer adopts a split design in which the graphics card is integrated in the keyboard, and the motherboard and processor are integrated in the screen, which is innovative and innovative. At the same time, Microsoft also announced that its performance is more powerful than Apple's Macbook Pro, which has attracted wide attention from digital enthusiasts. Today, let's take a look at what kind of black technology Microsoft has hidden in this small laptop.
Let's take a look at the configuration parameters of the Surface Book:
13.5 inch PixelSense multi touch display with 3000 × 2000 resolution (267 PPI)
6th generation Intel Core i5+customized NVIDIA GeForce GPU
8 GB memory
128 GB SSD
802.11ac standard Wi Fi wireless+Bluetooth 4.0
8 megapixel rear camera, supporting 1080p video capture+5 megapixel front camera
Equipped with pressure sensitive pen, the screen has 1024 level pressure sensitivity
Let's first take a look at the interfaces of the whole machine. On the right side are the Mini DisplayPort interface and the Microsoft specific SurfaceConnect port.
There are two full size USB 3.0 connectors and one SD card reader on the left side.
The screen and keyboard of the Surface Book are not connected through a magnetic interface, but through a mechanism called "Muscle Wire". We can separate the screen and keyboard by clicking the separation key on the keyboard before separating the screen.
We can connect the screen to the keyboard in reverse. The keyboard acts as a bracket for us to use the brush.
After separating the screen and keyboard, we can see the connection interface between the screen and keyboard. The screen is connected to the keyboard through the Surface Connect interface. In addition to data transmission, the interface also has the function of power supply.
Let's take a look at the front panel. The front camera array is very similar to the one on the Surface Pro 4. It has a 5 megapixel camera, infrared sensor, microphone and light sensor.
The rear camera is also similar to the Surface Pro 4, a combination of an 8 megapixel camera and a microphone.
Let's disassemble the screen first. Similar to disassembling the Surface Pro 4, we also need to heat the screen first to soften the glue, but the surface Pro screen is larger.
Use suction cups and paddles to slowly separate the screen along the edges.
We can turn the screen back first and then separate the cable. Different from the general design, the screen flat cable is welded on the main board, while the general design is that the flat cable is welded on the screen.
We found two strip buffer sponges on the back of the screen, which formed a drainage duct after combining with the body.
After removing the metal shield and foil on the screen, let's take a look at the chip on the display circuit board.
Red: N-trig DS-D5000 A0
Orange: N-trig DS-A5048 B2
Yellow: Novatek NT71394MBG 1520-ED KLNAH
Green: Wanghong Electronics MX25U4033E 1.8 V 4.0 Mb Multi in, Multi out NOR serial flash memory
We now begin to disassemble the fuselage. First peel off the foam paper covering the motherboard.
We found that the main board of the Surface Book covers a large area, almost covering the whole body.
Like disassembling the Surface Pro 4, we first remove the cover plate on the camera module.
The rear camera can be removed by separating the flat cable.
Let's take a look at the front camera module:
We tried to separate the front camera, but found that the front camera and the sensor were bonded to the motherboard. We decided to remove the motherboard before further separation.
There are many flat wires and cables on the motherboard. We use tweezers and crowbars to separate them one by one.
Remove the headphone jack, which is connected to the motherboard through a long flat cable.
Separate the speaker cables on both sides, and we can finally remove the motherboard.
The structure of the motherboard is relatively complex, with many cables arranged, and its shape is also very special.
Remove various flat cables connected to the motherboard.
A large number of flat cables indicate that the machine adopts a large number of modular designs. If there is a fault, the flat cable can be removed more like the corresponding parts.
Now we can finally remove the front part of the motherboard. Let's take a look at the fan, the ultra-thin 0.5Amp fan.
Next, we separate the heat dissipation module.
The heat dissipation module is composed of a huge copper plate and a heat pipe. The core part is coated with heat dissipation silicone grease, while the other parts have large heat dissipation stickers. There is a heat pipe at the far end of the heat dissipation module to help heat dissipation, so as to keep the heat away from the CPU and other parts as far as possible.
We disassembled the cameras one by one.
On the left is an infrared camera for face recognition. On the right is a 5 megapixel front camera.
Remove the SSD. This 128G SSD is provided by Samsung and its model is PM951.
This SSD looks familiar, just like the Surface Pro 4. Let's take a look at the chips on this SSD.
Samsung S4LN058A01 CIE 3.0 x4 NVMe flash memory controller
Samsung K9CHGY8S5C 64 GB NAND flash memory
Samsung K4E4E324EE 4 Gbit (512 MB) DRAM
Texas Instruments TPS22966 5.5V, 6A, 16m Ω, dual channel load switch
Now let's take a look at the chips on the motherboard.
Intel SR2F0 Core i5-6300U processor (3M cache, maximum frequency 3.00 GHz)
Samsung K4E6E304EE-EGCF 16Gbit LPDDR3 1867MHz SDRAM memory (4 chips, 8 GB in total)
Marvell Avastar W8897, Wi Fi/Bluetooth combination chip
Freescale Kinetis KL17 MKL17Z256VFM4 48MHz ARM Cortex-M0 +
Realtek ALC3269 Audio Codec
Infineon Technology SLB9665TT20 trusted platform module
Intersil ISL95857 1+2+1 voltage regulator
Here are some more:
ITE IT8528VG
Huabang W25X40CL serial flash memory
Wanghong Electronics MX25L4006E 3V, 4 MB [× 1/× 2] CMOS serial flash memory
Huabang W25Q128FV 128 MB serial flash memory
Next, let's remove the battery. There is glue at the bottom, and we use cards to slowly separate them.
The screen of Suiface Pro is equipped with a 18.0Wh 7.5V battery with a capacity of 2387mAh, which is officially rated to have a four hour battery life. The power consumption of this 3000 × 2000 resolution screen is relatively high.
Next, remove the "Muscle WireLock". This set of locking module can firmly fix the screen on the base. Only by pressing the removal button can the screen be separated from the base.
The locking module is electrically controlled. The U-shaped metal wire in the figure is a shape memory alloy, which will be rapidly extended when heated by electricity. Then the black pulley is pulled by the spring, the buckle slides inward, and the lock is released, so that the screen and the base can be separated.
There is a retractable metal spring on the buckle of the Muscle WireLock. When the buckle slides inward, the metal spring shrinks and the lock is released immediately. This little thing is the secret that the keyboard and screen can be so closely connected. Microsoft also claims that the Surface Book can lift the keyboard or screen parts at will without falling off, just like normal laptops. This set of locking module is very exquisite in design.
There are only speakers left on the base. The two speakers are independent.
Well, we are halfway through the disassembly of Suiface Book, and the disassembly of the screen part is over here. First, let's take a family photo of the screen part. Don't worry. The Surface Book is different from the Pro 4. The keyboard part of the Surface Book hides the biggest highlight of the machine - the independent video card. Please continue to follow our disassembly to discover the secrets of the Surface Book independent graphics card.
Now let's begin to disassemble the keyboard section. We start from the back. There are two rubber anti slip strips on the back. We heat them first to facilitate separation.
After removing two rubber anti slip strips, the edge of the lower panel is hidden below, and there are no screws.
There seems to be a lot of glue below. Let's heat it more to use soft glue, and use a paddle to pry it along the edge of the rear panel.
We have opened the rear panel.
After opening the panel, it can be seen that a large area of batteries are pasted on the back of the panel. The total number of these batteries is 51Wh 7.5V, 6800mAh. The battery in the base plus the battery in the screen part totals 69Wh, or 9187mAh.
We will first remove the SD card reader, which can facilitate us to further remove the USB control board.
After removing the card reader, we can easily remove the USB control board.
Let's see which chips are installed on it:
Freescale SC66 7334DC12
Ruiyu RTS5314 SD card reader controller
Huabang 25X40CLIG serial flash memory
Chuangwei Technology GL3520 USB 3.1 hub controller
Next, we can remove the most eye-catching graphics card of the Surface Book.
After removing the graphics card, we found that the design of this graphics card heat sink is very similar to that on the Mac.
The fan on the video card chip. Unlike the passive+active cooling of the processor part, this cooling fan on the graphics card chip needs to work for a long time. I don't know whether it will be dusty after long use.
After removing the radiator, let's take a look at this customized Nvidia GeForce GPU. According to the inference on the network, the model of this GPU should be GeForce 940M. Let's take a look at which chips are equipped on this video card:
Red: Nvidia N16S-LG customized GeForce GPU
Orange: Samsung K4G41325FC 512 MB GDDR5 video memory (1 GB for two pieces)
Yellow: Paradie PS8330B dual-mode DisplayPort V1.2 repeater
Green: Pericom PI3PCIE PCIe switch/multiplexer
Light blue: NXP CBTL06GP213EE six channel DisplayPort, HDMI and PCI Express multiplexer
Dark blue: Freescale Kinetics KL17 48MHz ARM Cortex-M0+microcontroller
The reverse side is very simple, without any chips.
This is the touchpad of the Surface Book, provided by Synaptics.
Next, we will remove this controversial segmented hinge shaft, and unscrew the screws to remove it.
Detach the real body of hinge shaft.
After the fixing screw is separated, various interfaces, cables, etc. on the hinge shaft can be replaced. If there is a fault, it is easy to repair.
Well, our disassembly is over here. Here's another photo of the whole family. The iFixit gives the Surface Book a maintenance score of 1 (10 is the easiest to repair), which is lower than the Suiface Pro 4. The maintenance is very difficult. Usually, such a low score can only be seen in Apple's devices. Except that SSD can be replaced, all components include CPU GPU、 The memory is soldered on the main board, and a lot of glue is used for bonding. The shell is difficult to disassemble, so it is not recommended that users disassemble and replace the parts themselves.
