Everyone is friendly. I am air04 that reveals the true side of the product. Members who are particularly interested in the four-and-fifth part of the review want to see different evaluations.
I. Introduction:
It was also from the launch of Apple’s first-generation iPad in 2010 that the tablet finally began to enter the public eye, before it was often classified as a popular niche type. Nowadays, various Android, iOS, and Windows tablets on the market are dazzling. Numerous models are introduced each year. However, users who focus on efficiency and work needs will eventually choose the flat panel of the Windows system. Tablets for Android and iOS systems are more focused on entertainment functions and have many limitations and inconveniences for office use.
Windows system has high requirements for system hardware resources. Intel's Atom series processors were first used on the first batch of Windows tablets competing with iPad. ATOM's cowardly performance has not unexpectedly dragged down the user experience and has caused constant bad reviews.
The design of the tablet is not easy. To balance the appearance, material, weight, performance, heat dissipation, stability, and expandability in the limited space under the fuselage , any defects will lead to the whole machine. "effects" , thus affecting the user experience. Microsoft Surface has made a good start for the tablet notebook. It is also the first time that it has succeeded in translating the tablet with productivity to the laptop, and it is no longer just a piece of pie together.
After absorbing many advantages of Surface, Thinkpad first attempted a major innovation, letting the tablet get rid of the shadow of the notebook and evolving to specialization. In the full use of the advantages of the tablet itself, the use of modular accessories to expand the function of the tablet. So what is the performance of the Thinkpad X1 Tablet as a function of its own? Can you support these capabilities perfectly?
Second, the fuselage function and design:
The overall style of the Thinkpad X1 tablet follows the ThinkPad design language.
Only the back bracket sells its tablet identity.
ThinkPad's genes are back on the Thinkpad X1 Tablet. The red dot and three-button touchpad are all available. It’s also inherited.
Lenovo's logo is just right in color and position on the body, and it is not unexpected and has a good presence.
Add a bit of red to the all-black color and add the finishing touch
Cortex keyboard hinges, with the role of adjusting the height of the keyboard. When the brand new hinge is hard, it will not be docile on the screen. After many times of folding, this phenomenon will gradually disappear.
Fingerprint recognition, the same press style as the iPhone, no need to slide your finger. Just not pressing the function cannot be used to wake the screen. If you set this button as the power button, it's even better. You can start it all at once.
The recognition speed is between iPhone 6 and iPhone 6S, the recognition rate is high, and there is good compatibility with dirt.
Front camera, next to the privacy light for the hole. Some models also have an infrared camera next to the camera for face recognition and other security settings.
Multiple MIC openings in the front for pickup and noise cancellation. Multiple MICs have the advantage of allowing the tablet to record sound at any angle, making videoconferencing even easier.
Thinkpad X1 Tablet does not use a non-border design, all angles of the border can accommodate a thumb placed without touching the screen. Yes, this is an advantage on the tablet. The tablet design is different from mobile phones and laptops. The pursuit of borderlessness will only sacrifice the gripping experience and increase the risk of crashes. Air04 hates the narrow and narrow side design of the iPad mini. When the bare metal is upright, it can't hold it.
The exposed contacts at the bottom provide power and handshake for the original keyboard.
After the protection bar is removed, you can see the data interface used by the function module alone, which is used to link function modules to extend USB and HDMI interfaces.
There is only one power button at the top of the fuselage on the left side. When holding it on the front, just press the power button on the left index finger and press the fingerprint on the right thumb to unlock. Light up to enter in one go. Carefully observe the power button to see the drawing design. 
The volume button on the left side of the tablet also uses the same design, and the key press feels good. 
Each of the speakers has a sound quality, and the sound quality of the two-channel sound can be clearly felt when listening to music on the flat panel.
In the figure, the left side of the sound outlet is the anti-theft interface. The anti-theft interface can also be used to connect the lanyard in addition to the anti-theft lock rope, especially when hanging outdoors in the arm or belt to avoid accidents. Many flat-panel security locks have been reduced, it is really regrettable.
The right side of the Thinkpad X1 Tablet is a mini DP connector, USB 3.0 type-A, and USB 3.0 type-C. The Thinkpad X1 Tablet does not have an interface design that is too advanced like a Mac Book, and the addition of the USB type-A port makes it easy to connect various devices when you go out without having to carry a patch cord like a MacBook or XPS12. The miniDP interface can switch out various video interfaces, and is more compatible with various models of projectors to ensure the smooth progress of the demonstration.
The USB 3.0 type-C also works as a charging interface, but it cannot be used to charge the Thinkpad X1 Tablet with QC2.0 and QC3.0 chargers. Mobile power is also not acceptable. It's probably the same as the Mac Book, and only chargers that are original or specifically decoded can be charged.
The red belief light on the ThinkPad logo on the back can be lit, or it can be judged whether it is in the on state according to the status of the light.
The camera has a low level of presence on Windows systems. Windows 10 does not even have a camera software. The main use of its main camera is probably the sweep bar code and two-dimensional code, fill light just can improve the bar code recognition rate under low light.
Hidden TF card slot. Supports TF card storage expansion. The actual test supports the maximum capacity of the TF card currently sold and the memory card can run at full speed of 80MB/s. It is faster than the USB2.0 maximum speed limit and should have the speed of the USB3.0 interface. If you can support SD card expansion is even better. The speed capacity price can be a good balance.
The hole in the top of the TF card slot is a hard reset button to solve the crash.
Bracket:
The way behind the stent deployment is rather special. I have seen many value-friends comment that this open method is not stable enough. In actual use, it is found that the shaft is very tight, and even I have to suspect that using such a large force will break the bracket. 
The bracket is normally locked by a unilateral magnetic fastener and is directly absorbed on the other side. The actual use did not appear to be loose on the Internet. The adsorption was smooth and natural. If you are not satisfied with the adsorption force, you can replace the magnet in the back cover.
The stand can be expanded 55 degrees-85 degrees so that the plate stands on the table.
Bracket angle can be adjusted steplessly, extending the scope of use
Office typing can be just like a notebook, not limited to a fixed angle.
The special design of the bracket can also be opened by 90 degrees, allowing the flat panel to be tilted and placed on the desktop. In practice, this angle is more conducive to the use of the module and improves stability.
keyboard:
In addition to the addition of the tablet, the designer retained all ThinkPad elements on the ultra-thin protective cover.
Three physical touchpads are more convenient to use and are more suitable for Windows operations
The classic Little Red Riding Hood returns with a smooth feel like the PSP rocker. Do not try to pull off the little red hat. This is glued on the back.
The keyboard also incorporates trendy elements: backlighting. It can be turned off, low brightness and high brightness as required.
Indicators are complete, which is not common on laptop keyboards.
Although the shape of the keys does not seem to be the classic feel of the middle recess, it does not actually exist. This is just a visual effect.
Keyboard height can be adjusted. Many evaluations including official instructions say that there are only 2 heights, and 3 segments need modules. Is this true?
In fact, it can also be folded like this
Together with direct leveling, there are a total of 3 height adjustments. It is also the cleverness of this keyboard hinge design.
The fuselage cooperates with the magnet on the keyboard and the hall sensor of the fuselage, the screen will be unlocked automatically when the keyboard is folded as shown in the figure.
Restoring the keyboard will automatically lock the screen and make it easier to use. Thinkpad X1 Tablet has been optimized in many details, making use more comfortable.
Stylus:
Ordinary tablets use only touch to operate, but this control method is extremely difficult on high resolution screens, especially on 2K resolution screens like the Thinkpad X1 Tablet. When an efficient and accurate operation is required, an electromagnetic stylus is far more portable and convenient than a mouse.
The Thinkpad X1 Tablet's stylus comes from Wacom. Wacom is a well-known provider of tablet and pen-touch touch screen solutions. The stylus equipped with the Thinkpad X1 Tablet uses 2048 pressure sensing technology to reflect the speed and sensitivity. The pressure level is even twice as big as Wacom CTL-671's 1024. The touch screen is WYSIWYG. There is an incomparable advantage of the digital tablet. Drawing and drawing are closer to the tradition, reducing the difficulty of getting started.
The red circle at the end of the stylus is ThinkPad.
The stylus body is made of metal and the body of the pen supports two buttons for customization.
Custom features cover almost everything, only unexpected, not impossible. I set one button to scroll and the other to right click. Professional users can define erasers and other tools when drawing.
Stylus brings high precision and it also brings a little trouble. Many flat panels with electromagnetic stylus will appear inaccurate edges, and the Thinkpad X1 Tablet provides calibration in software, avoiding long-term use. Drifting caused by induction.
The two buttons on the pen are only slightly raised and are integrated with the pen body. If you can, it is recommended to add a bump on the key to facilitate blind press.
The sleek pen tip moves smoothly on the screen, and the pen tip part is designed with a unique shape to match the original pen holder. The stylus has a personalized setting, which automatically blocks the touch when the stylus is placed within the screen detection range. When using the stylus, palm can be placed on the screen without worrying about accidental touching.
Handwriting recognition software comes with the system is also very easy to use, finger scrolling screen + stylus accurate click more convenient than the mouse.
charger:
Thinkpad X1 Tablet's charger does not use a series of square charging ports, but with the same interface USB3.1 type-C.
In addition to supporting the Thinkpad X1 Tablet's own 20V output voltage, the output voltage has 12V and 5V voltage supply. Theoretically, it should support mobile devices such as cell phones that type-C interface directly to charge. However, there is no response to plug in the 4C, but no cell phone is burned. What protection mechanisms should be used to avoid misuse, and it may be necessary to think of their own devices. stand by.
Different from the ordinary Type-C interface, the interface of the Thinkpad X1 Tablet has a fixed shrapnel on the head. When the interface is fully inserted into the computer, it will obviously feel stuck. Pulling out requires a greater force than the normal interface, but also to prevent poor contact due to loose connectors after frequent insertion and removal.
The plug is unfortunately not foldable, and it is recommended to design it for folding or easy removal to reduce the carrying volume
weight:
The three points of performance, lightness, and sturdiness are always on the opposite side, and only those three points can be unified. 
Thinkpad X1 Tablet main body weighs only 0.75KG, in the notebook is very lightweight, in the flat is a heavyweight player, even if it is also a little lighter than the Surface Pro4.
The carrying weight of the protected keyboard is 1.06KG.
The full weight of the trip is only 1.25 kg. Many laptops or flat panels that promote their ultra-lightweight and slim are equipped with a heavy and big power adapter. Dare to compare the weight of travel?
Third, performance and experience:
Early Windows tablets use processors such as the ATOM, which can't be guaranteed even when the basic system is fluent. It's really not a good experience. It can be called torture. Thinkpad X1 Tablet uses the new low-pressure processor M5-6Y57 fanless design, then its performance?
Overall performance:
The processor I use for this Thinkpad X1 Tablet is the M5-6Y57 version. The M5-6Y57 is a dual-core, four-threaded processor with 4MB of cache and the highest core frequency to 2.8GHz.
Different from ordinary notebooks, the tablet is rarely used for long hours and pressure. In addition, the new M5-6Y57's low-power high-performance, Lenovo's full range of Thinkpad X1 Tablet adopts a passive cooling design. This benefit is obvious to users who often use laptops, and you don't have to bother to clean the radiator's dust . It is also this way, the body can reduce the heat hole, a certain degree of resistance to wind and sand instead of the powerless.
PCMARK 8's HOME test gives a 2131 overall performance score. In contrast, the MacBook Air 2012 score of i5-3427U was 2289, which was only 158 points apart. The fanless design of the tablet to achieve this performance in the default settings is already very good.
In the WORK test in PCMARK 8, Mac Book Air 2012 was only 2750 points. The Thinkpad X1 Tablet scores in the above chart cannot be pulled apart. It can be said that the experience available on the Mac Book Air 2012 is also available on the Thinkpad X1 Tablet.
Game performance:
Look at the performance of the complete machine and then take a look at the performance comparison of the game. Excluding many interference factors such as the resolution, the performance of the processor and the processor itself is clearly compared, and the outcome is obvious. In the Cloud Gate test of Mac Book Air 2012, only the physical test of the processor's computing power can be leveled, and the video card's loss to the Thinkpad X1 Tablet is 515.
In the Sky Diver test, the gap is equally evident. The Thinkpad X1 Tablet with the M5-6Y57 leads 24% directly. The i5-3427U lost all sub-tests. The fan-less design of the M5-6Y57 is not as weak as expected, but it has already surpassed the need for fan cooling in 3-generation i5 low-voltage processors without forced overclocking.
Playability:
The classic duck 4K video test, thanks to HD515 native support 4K resolution decoding and output, the CPU occupancy rate is very low. There is no pressure on hard decoding of 4K high bit rate video . Using the tablet with miniDP interface output is very suitable when the demo host or as a media player.
Master Lu evaluation:
Master Lu is also dubbed the entertainment guru.
In the processor test did not reach the full load of the processor, Turbo frequency has not been to 2.6GHz, so that the test can really reflect the performance.
The same is true for subsequent processor subproject tests.
The wind of the whole machine was 62260, of which the processor contributed 22,603 ​​points.
Processor ranking 578. 
Graphics performance is only higher than 4600? ?
The performance of the whole machine is terrible. What is the situation?
Once again, disk performance beats 1% of the country? ? ?
It's also a SSD, although it's a SATA channel, it's not a weak one.
How can I not read and write overall performance in 1%? ?
Whether it is TF card or built-in hard disk read speed faster than ordinary laptop hard disk. Well ... can only say professional evaluation or let professional software come.
screen:
The 12-inch IPS mirror display is crisp and clear. Thanks to the high resolution of 21601440, you can get a good visual experience whether browsing the web, reading a PDF, or watching a movie.
The gamut reaches 96% sRGB, giving it the basic quality requirements for image processing.
The average color difference is only 1.44, and the overall quality is satisfactory. This is also a must-have for an excellent tablet.
In Windows 10 to modify the text and application size, in order to avoid the ultra-high resolution under the text icon is too small, but air04 still like ordinary 100%, as much information as possible in a page.
Browsing a webpage in notebook mode leaves more white space in the left and right part of the webpage
Put the tablet upright and the web page is right. The homepage has a total of 4 more recommendations and more to see.
Browse original is also more convenient, which is the biggest advantage of tablet relative to ordinary notebook.
Ordinary notebooks use the horizontal screen mode to see an original one needs to be scrolled many times, and the picture cannot be displayed at one time, which affects the reading experience. This is not as convenient as the Thinkpad X1 Tablet.
The high-resolution screen with smooth performance is very suitable for quick browsing of web pages.
wireless network:
Thinkpad X1 Tablet uses Intel's 8260 network card, using two sets of sending and receiving antennas, respectively, on the left and top of the screen, fully optimized after the adjustment of the signal receiving effect is good. The 8260 supports 2X2 MIMO 802.11AC networks, allowing users to freely choose between the more capable 2.4GHz mode and the faster 5GHz network. 
Use “New Millet Router (2nd Generation)†to copy data via the wireless network and the Thinkpad X1 Tablet. The copy speed is 5-6 MB/s. The router capacity limit has been reached.
Use a USB network card to connect to wired Gigabits of course to get faster speeds. However, the powerful wireless capabilities of the Thinkpad X1 Tablet can handle 1080P video, and even low-rate 4K video playback is no longer under pressure, as long as your router is fast enough.
Life:
Since the mobile power supply cannot be used, the life of the tablet itself is very important. Fortunately, Thinkpad X1 Tablet with 37Wh built-in battery is very powerful, comprehensive office entertainment using no problem under 5 to 6 hours, even after playing two 120GB length of 25GB movie there is the remaining battery. Some evaluations like to say 8 hours of continuous flight time. The actual measurement can only be achieved after adding an external 24Wh battery.
If you have to compare the battery life of the Thinkpad X1 Tablet horizontally, then I can say that it is almost the same as the Mac Book Air 2012 running OS X. There is no pressure to go out without a charger to cope with work. If you need a full day of work, entertainment, or recommend the purchase of an external battery, fortunately, the price of 599 yuan battery accessories is not too expensive relative to other Thinkpad X1 Tablet module. Buying multiple replacements can extend your life time indefinitely.
Special feature:
Many of the features of the Thinkpad X1 Tablet are not purely software-dependent, requiring a chip on the motherboard that supports these features. Simply transplanting software to other tablets can't realize full function migration.
In the Thinkpad X1 Tablet, settings can be made through the Lenovo Settings Center.
IntelliSense is relatively rare on the tablet. These features can reduce misuse of the screen and increase the life of the tablet.
Battery control is very powerful. It is recommended to turn on the smart cooling function. The smart cooling function can allow the whole machine to run in a state of balance of performance and heat. Even though it is turned off, it will obtain short-term high performance. However, the subsequent heating will trigger the processor to automatically down-clock, which will affect the use of the device. Experience.
Thinkpad X1 Tablet's battery power statistics function is to calculate the remaining power of the battery for power consumption and time, which is very different from the low-cost Android phone relying solely on voltage. This algorithm is more accurate and is not affected by the practical use of large loads. It is only because the battery attenuation will make the power statistics less accurate after prolonged use. Normally the device can only be constantly fully charged and fully discharged to calibrate, and the Thinkpad X1 Tablet provides calibration directly in the setup, reducing maintenance time in daily use.
The old driver of the battery should know that the lithium battery keeps its maximum power for a long time without using it, which will affect the battery performance and even damage the battery. This is why your notebooks are always full of power, but for a long time you find that the battery is broken.
Thinkpad X1 Tablet this feature can be very good to avoid this situation, very user-friendly design.
The low-power mode, which is recommended when the chat does not require strong performance, can increase a lot of battery life.
The touchpad is turned off individually to prevent accidental contact. I prefer to also add a pointing stick to close alone.
Multiple MICs on the Thinkpad X1 Tablet enable noise suppression to improve the quality of video chat or conversation.
The Thinkpad X1 Tablet does not have a separate light sensor. Instead, it uses the same light perception of the camera as the Mac Book to determine the brightness of the monitor.
The Paper Display function is a very interesting setting.
There are several scenes in the function
Paper Display is similar to the Night Shift on iOS. It adjusts the display's color temperature to yellow the screen for easy reading. The screenshot can not be directly reflected, it should be to directly adjust the driver and other hardware to achieve. Although Paper Display is a non-essential feature, it can greatly enhance the user experience.
Lenovo Companion, another software built into the Thinkpad X1 Tablet, manages the performance and drivers and updates of the entire tablet at the touch of a button. Unlike those who only pay attention to the heap on the hardware, Thinkpad X1 Tablet is more attention to detail and experience. It simplifies many tedious operations to just one click.
The biggest annoyance for laptops and tablets is probably to update the BIOS, a brick accidentally. On the Thinkpad X1 Tablet, even this annoyance is reduced to just one click.
The built-in library also has some software and article suggestions such as tips.
Fourth, ice and two heavy days: adapt to environmental testing
As a tablet computer, its greatest advantage lies in its portability and its use anywhere. Tablets are more suitable for outdoor use than keyboards that hinder the expansion of the notebook. The biggest change in outdoor sports is the temperature. You don't want to find out when Heilongjiang camping is too cold. You won't want to hang out in Nanjing. So Air04 took everyone to explore where the ultimate Thinkpad X1 tablet is.
Low temperature test:
Sealed with sealed pockets, evacuated and placed in a freezer at -18°C for 10 hours
The fanless advantages are reflected here. Because there is no need to use air to take away heat, you can use a sealed bag to cover it when going out to prevent rain and sand from invading. If it can be completely closed by wireless charging, adaptability will be even more.
Surface, ice water mixed. The surface temperature is around 0°C. The internal temperature is at least -15°C
Click the boot button to say goodbye ... ... ... ... automatically shut down. Thinkpad X1 Tablet has low temperature protection.
After more than 10 minutes of continuous attempts to boot, it finally opened successfully. At this point the surface temperature is still 0 °C.
After the boot was successful, the battery level had dropped from 100% when it was put to 94%.
After the boot, the surface temperature rose to 10°C, and all functions returned to normal. No instability occurred.
High temperature test:
You may not go to Nanjing in such a hot summer place, but you may forget about the tablet in a hot car. You may need to display the blueprint on an air-conditioned site. You may need to test the instrument in a high-temperature room. If the Thinkpad X1 Tablet can't withstand high temperature baptism, these tasks can't be done with it.
The M5-6Y57 frequency is 1.1GHz and the maximum can be 2.8GHz. In the random processor frequency monitoring, it can be seen that when the 2.4 GHz load test is performed on the processor, the processor does not directly clock to 2.8 GHz, but it floats between 1.6 GHz and 1.8 GHz.
At the ambient temperature of 23 degrees, the final processor temperature was stable at 75 degrees during the load test. For a fanless design, the temperature control was good.
The maximum temperature on the back of the plate is 44.7 degrees, and it is mainly near the processor position. Heat spreads from the center to the surroundings, and the alloy back cover plays a role in assisting heat dissipation.
When the ambient temperature was measured at the ambient temperature of 39 degrees , the processor temperature was finally stable at 85 degrees. There was no problem with the crash. The frequency was still floating between 1.6 and 1.8 GHz, and there was not much change in performance when the ambient temperature was 23 degrees. Of course, if you want to let the processor operate at a high frequency, you can also try the ice.
V. Xiuwai Huizhong: Dismantling Analysis & DIY Extensibility
Note: The power light does not turn off and it does not indicate that the internal voltage is zero. When installing or replacing parts must be strictly in accordance with the operating manual. Always turn off the computer and unplug the power cord before installing.
There is no purpose of the dismantling is rogue, it is not difficult to understand the value of the value of doubt dismantling friends. Air04 has two main purposes in this dismantling:
1: reveal the internal work of the Thinkpad X1 Tablet and see why the Thinkpad X1 Tablet sold so expensively. Is it worth the price?
2: Check the internal interface reservation and check the feasibility of the DIY function.
Air04 found out that the Thinkpad X1 Tablet has many special features in addition to the features officially described by the Chinese government at the time of reading the official manual. Most of these functions are freely customizable on the Thinkpad official website in the United States. The following features can be customized: Infrared camera, NFC , WiGig, WWAN 4G Internet , GPS and more. So how many functions in the fuselage can be DIY to achieve it?
The back of Thinkpad X1 Tablet is made of metal material, which not only enhances the rigidness of the whole machine, but also assists in heat dissipation.
The back cover uses a screw + snap fastener. The right side of the screw on the drawing is...
With the bottom two fixing screws, the whole machine uses 5 screws to fix the back cover.
Internal list. The battery occupies most of the entire panel, and many circuits in the aircraft need flying wires for this purpose.
The battery interface is special. Even if it is lifted up and disconnected, it is still hooked by the end of the buckle and cannot be completely separated. It is designed to ensure that it will be severely impacted during daily use and will not be disconnected.
Many strong magnets are visible on the bottom of the fuselage
These strong magnets are used to hold and secure the keyboard. 
Battery is a combination of two polymers
Provides 7.5V 4935mAh capacity. Note that the voltage is 4935mAh at 7.5V, much greater than 4935mAh at 3.7V.
Corner sub board, mainly provides boot and volume buttons and headphone jack function. Both the interface and buttons are embedded in the motherboard and can withstand heavy pressure without falling off.
The micro-motion of this type of packaging is much more durable than the type of shrapnel used in ordinary flat plates, and the chance of poor contact is also small.
Main Wifi antenna on top of tablet
Rear camera
The early flats were not equipped with fill lights, which greatly limited the scope of application of the camera.
Here is the location of the NFC antenna.
The socket of the NFC module on the mainboard is retained, and it can be directly installed and used as long as the related accessories can be found. 
Thinkpad X1 Tablet's belief light is achieved by this line. As long as the host is in the running state, it will light up to check the running state of the host. It can also identify whether it is possible to...hmmm...because the main camera is started without a warning light.
Thinkpad X1 Tablet second board, module and keyboard connection port. The keyboard and module do not take the same data cable. In fact, I suggest that the keyboard directly use the Bluetooth connection, and the application range will be much larger. After all, the keyboard does not have functions such as batteries and card readers.
Thinkpad X1 Tablet one of the important optional features of the 4G Internet in the foreign official website can be customized, the licensed version of the motherboard still retains the SIM card slot, this is a great point, to achieve 4G function does not need their own Manually weld the card slot.
The slot of the card slot has only a small plastic baffle, which can be pushed open by gently pushing it out from behind. The rest of the work will only need to find a WWAN EM7445 card to insert an empty card slot. Buying two antennas and affixing it can perfectly implement 4G Internet access.
The host's TF card slot has been tested to support a read/write speed of 200GB TF card 80MB/s.
A hard-restart button is located next to the TF card slot. The button is covered with a layer of glue to prevent the micro-motion from being damaged. There is only a small hole in the body, it is easy to ignore if you do not pay attention
Intel 8260 wireless network card, soldered directly to the motherboard, can not be replaced.
WiGig module location, unfortunately not using the socket form. If you need this feature, you must buy the Thinkpad X1 Tablet with this feature.
This use of shielded enclosures is not common in low-end notebooks.
In general, such shielded shells protect the important originals from interference, but here only a set of power supply circuits is shielded. A little extravagant workmanship
Here is the famous M5-6Y57 chip 
Export of heat to the housing through copper foil and metal frame, no fingerprints found
Removing the 4 screws will reveal that the X-frame is a shrapnel and the heat-conductor is compacted on the processor chip. This type of heat sink can be seen on high-end ultra-thin notebooks.
The entire chip is soldered on the motherboard
No lettering on the top of the chip itself
The legendary M5-6Y57
Memory section has a separate heat sink/shield
Elpida produces memory particles with a single capacity of 2GB. In the flat panel system, it can be seen that they are divided into two groups to form two channels.
Thinkpad custom chip
Realtek 5232S FB164Q1
Puri provides touch control chip
Realtek ALC3268 Realtek sound card chip is also common on Lenovo laptops.
WWAN card has a dedicated slot
Not only did the outlets not have a reduction, but the workmanship was also very good.
SSD is carefully wrapped in copper foil with plastic insulation on the inner layer
Disassembly is very simple
SSD is provided for Samsung.
Universal M.2 interface, this SSD is taking the SATA channel, in the highest version of the Thinkpad X1 Tablet version of the SSD to take the PCI channel, the reading speed can exceed 1GB/s.
If you need to replace the hard disk, be sure to remember to use a single-sided SSD . Since the internal space of the camera is relatively limited, using a double-sided SSD will not cover the back cover.
This interface fixing method can only be seen on high-end notebooks or tablets. All interfaces are not only very strong welded, but also have an additional stainless steel frame that is unlikely to fall off even at high frequency.
The keyhole on the body is not just a decoration, the keyhole itself and the body alloy frame as one. The use of violent demolition will certainly lead to serious damage to the fuselage frame.
Suspended sound unit design, basically also be regarded as a high-end standard.
The left and right vocal units are symmetrical.
Many valued users will worry that the heat of the processor and SSD will be directly exported to the screen, leading to reduced screen life.
On the Thinkpad X1 Tablet, the designer intentionally suspended the motherboard between screens. There is a distance between the motherboard of the SSD's frame and the CPU's location and the screen. Reduces direct heat transfer. It's far better to stick the board to the screen than the low end.
The back cover of the Thinkpad X1 Tablet is completely made of metal. The surface is only sprayed with a layer of skin-friendly material that feels like plastic.
The rear cover is covered with such shielding contacts.
There is no need to worry about the strength of the bracket shaft.
The thick hinges and multiple fixings allow it to maintain excellent features and feel for long periods of time.
An insulating layer is also attached to the contact surface between the back cover and the bare part of the main board
The bracket locking lever is an exquisite design, and the locking element itself does not have any physical contact. It is purely relying on the repulsive characteristics of the magnet to control the adsorption and ejection of the bracket. This design greatly extends the life of the latch and also reduces the occurrence of faults and damage. A snap may be done on the low-end tablet.
Sixth, summary:
System drag experience: 
Need to give up, although the Thinkpad X1 Tablet in the test can feel the engineers to make every effort to provide a better experience, but the entire high load test is simply a fight with Windows10.
In the system, the operation of the stylus pen and the touch control is not equivalent to a mouse click, that is, two different operations. This led to the direct failure of the touchscreen or stylus click in the game (Steam platform Game Age of Empires II), I would like to disappoint on the tablet to experience the real pointers under the RTS.
advantage:
1: High-strength ultra-thin metal body, skin-friendly coating has a good coefficient of friction, which facilitates gripping.
2: Without sacrificing feel. With no border design, the corners of each corner can accommodate a thumb without accidentally touching the screen.
