Compared with the extreme performance and heat dissipation of the game book, we prefer to polish it carefully for the sake of thinness and longer life. The HP Star 14-CE0028TX that this article will start with is here. So whether HP Star 14-CE0028TX is portable enough, whether the experience in the scene is enough, and whether the performance is strong, these are the key points to be discussed in this paper.
Let's get started, don't bother unpacking. Design is often our first impression of notebook computers. The HP Star 14-ce0028TX I received is a champagne gold version.
The first is the design of the A-plane. In the middle of side A, HP's brand Logo is highlighted, and the antenna design above ensures that the WIFI connection can be kept good and uninterrupted.
Next is the B side, and the screen is designed with micro-borders, but it does not achieve the effect of narrow borders on three sides.
HP STAR14-CE0028TX still chooses the traditional border layout with narrow left and right (5.52mm micro-border) and wide top and bottom.
The C plane is naturally the area of the keyboard. First of all, from the color integrity of the surface where the keyboard is located, it must be praised. The material is all metal except the keyboard. The whole keyboard area adopts sinking design, and the reserved area can ensure the gap with the screen and play a certain buffering role.
Let's talk about the feedback strength of the keys first. The key stroke of 1.5mm feels moderate, comfortable and natural, and the distance between keys is just right, so it will not be touched by mistake. Keyboard backlight is available, mainly characters and sidelights.
At night, the backlight brightness is considerable, although my daily use environment is excellent, even if the bedroom is equipped with a desk lamp. But there will always be a bad environment inadvertently, so the existence of keyboard backlight means that I can live without it, but you can't live without it.
HP Star 14-CE0028TX chose to place the sound system at the junction of B and C, which is also a popular practice. A long diamond-shaped speaker grille opening area crosses the B surface, which can be used to improve the sound on the one hand and dissipate heat on the other. The angular design is also very novel.
Compared with the Logo on the back, the HP logo here is more compact and smart.
The power button is located in the upper left corner of B-plane, which requires a little more pressing force, also to avoid accidental touch. In the center of the power button is a strip-shaped white indicator light, which is used to identify the on-off state of the computer.
The touchpad area is obvious because HP Star 14-CE0028TX did not press the left and right keys to cut, but remained intact, and the color treatment was consistent with the surrounding.
There is a piece of propaganda paper in the lower right corner, which is pre-installed with Office 20 16 Home Edition, built-in i5 8th generation processor, NVIDIA alone and so on. Most notably, HP Star series is equipped with Danish international audio B&B&; O sound effects, let's talk about it later.
Then, let's take a look at the interface part of HP 14-CE0028TX. I. Left side: two USB3.0 and 3.5mm audio interfaces, anti-theft lock and SD card slot.
Right: fingerprint reader, Type-C, HDMI, network cable interface, power DC interface. In particular, I specifically asked the official customer service staff to confirm that the Type-C port is not Lightning 3, but USB 3. 1 Gen 1 specification, which naturally does not support PD charging. The biggest difference between USB3. 1 Gen 1 and Gen2 is that the maximum transmission rate of the former can reach the theoretical bandwidth of 5Gb/s, while the latter can reach the theoretical bandwidth of10 GB/s. At present, most manufacturers claim that the Type-C port on the device supports USB3. 1 standard devices, but actually, The real USB3. 1 is the Gen2 standard.
The existing value of fingerprint reader is that users can easily enter the system without entering complicated passwords when they are turned on. Judging from the actual experience recognition rate, it is still relatively efficient. Personally, I think it may be more convenient if it can be integrated on the power button.
HP Star 14-CE0028TX has a side treatment as thin as 17.9mm and a whole machine as light as 1.59kg, which belongs to the portability category.
In order to better control this portability, it uses an escalator-type rotating shaft, and the bottom of the screen adopts a radian design, so that it can become the supporting point of the notebook after opening and closing.
Hewlett-Packard officially calls it butt joint, which has the advantage that the hand can be placed at a certain angle on the C plane, which is convenient for keyboard input.
There is a long opening on the inner side of the rotating shaft, which plays a certain role in cooling the side of the motherboard, which is also a common practice of thin and light cost now.
Finally, let's take a look at the D face of HP 14-CE0028TX, which gives the first impression that it is extremely refreshing. Small holes are densely distributed in the top heat dissipation area, and there are soft rubber pads at the four corners, which can protect both desktops and laptops. However, I have to spit out the material of surface D- plastic. Why do you want to spit? Please see the disassembly.
After talking about appearance, we naturally need to explore the inside, and undressing at one time is the best choice. However, when I removed the three screws at the bottom of HP 14-CE0028TX, I found that the back shell could not be removed. After contacting the customer service in JD.COM, I found that the two foot pads at the top were detachable, and each foot pad contained a screw, but fortunately, the foot pads were designed to be pasted repeatedly.
The position of prying open the rear shell is located at the rotating shaft. I used a screwdriver for a long time. I heard that the fresh plastic crowbar broke before it was opened. The plastic on the back is easy to leave scratches when prying, but fortunately it is at the bottom.
After complete disassembly, as shown in the figure below. I thought HP Star 14-CE0028TX kept it from me, but later I thought it was too much. In fact, its internal workmanship is excellent.
The first is the mechanical hard disk part in the lower left corner, which is quite satisfactory, but the data line part is still relatively reluctant.
The specification of SSD is Sandisk X600m.2 2280, 128g, which adopts 3D NAND technology, and its power consumption is lower than that of the previous generation X400, and its theoretical sequential reading and writing speed is 530MB/S and 490mb/s.. ..
In terms of memory, HP Star 14-CE0028TX has only one slot, so if you want to upgrade, you may only need to directly add a single specification of 16G.
HP Star 14-CE0028TX adopts Samsung DDR4 2400MHz 8G version, and Dachang granules are still guaranteed.
The battery is embedded in the motherboard with a capacity of 40286mWh.
The wireless network card is Winyao Intel AC 3 168 NGW wireless network card.
As can be seen from the data in the figure below, this wireless network card integrates Bluetooth and supports 2.4GHz and 5GHz, but it is only a single antenna with a maximum speed of only 433Mbps.
In terms of heat dissipation, HP Star 14-CE0028TX is quite satisfactory, with double copper pipes and double fans, which is enough to suppress i5-8250U and MX 150.
Interestingly, the main board structure of HP 14-CE0028TX did not choose a whole PCB, but designed a small board on the left interface, which was connected to the big board through a flat cable.
The structure of the rotating shaft is exposed, and the lubricating oil on it shows the required working state, but personally, it is more appropriate to close the rotating shaft.
In terms of interface, HP 14-CE0028TX is distributed on both sides, but I want to make a small suggestion. If USB ports can be distributed on both sides, it can better meet the access requirements in different directions.
Finally, let's take a look at the back shell of HP Star 14-CE0028TX. Although it is made of plastic, the contact part has been treated with heat dissipation.
Half of the elongated cooling hole is covered with a filter screen corresponding to the position of the fan to filter the sucked dust.
Screen quality is often a point that notebooks at this price are unwilling to mention, but as a tester, it is also a point that cannot be ignored. So how did HP Star 14-CE0028TX perform? In order to ensure the objective and accurate test data, firstly, let HP Star 14-ce0028TX warm up at least 1 hour, and turn off the color gain function that may affect the test results. The test tool is my Datacolor Spyder5 elite Starscream 5th generation screen color calibrator, and I made its original ICC file.
(1) Color gamut coverage
As can be seen from the figure below, the color gamut coverage of HP Star 14-ce0028TX is 63%sRGB and 47% RGB.
(2) color accuracy δ e
The value of color accuracy δE reflects the difference between the display and the standard value, so the smaller the value, the better. The higher the score, the more distorted the color. The test results are shown in the figure below. For the 48 colors tested, the average δ E value is 1.40, with the minimum value of 0.28 and the maximum value of 5.74. The color difference between red and cyan is a bit noticeable. In addition, the δ E values of most colors are below 2, and the overall performance is excellent.
(3) Chromaticity uniformity
In the chromaticity uniformity test, the yellow block represents the difference between the screen color temperature value of each block of the screen and the standard value, and the larger the value, the darker the color. (Note: The smaller the maximum difference, the better, which means it is closer to the standard value of D65; otherwise, the larger the value, the lower the brightness. )
As can be seen from the above figure, HP Star 14-ce0028TX has a good performance in chromaticity uniformity. In the D65 standard, the color temperature value of 6500K indicates that the color is more accurate, neither too cold nor too warm. Through the test, it can be seen that the color temperature in No.8 area is closest to the standard of D65, while the color temperature in No.7 area is quite different from the standard color temperature value, with a difference of 3.3.
(4) Brightness uniformity
The test of screen brightness uniformity is also carried out with the help of the fifth generation screen color calibrator of Datacolor Spyder5 Elite. Divide the screen into nine large areas, test and calculate the brightness and chromaticity coordinates of different percentages of the screen in each area, and finally draw the following conclusions. (The following results are all tested when the IRE output reaches 100%, that is, when the maximum brightness and contrast output are used).
The gray part in the above figure represents the brightness distribution of HP Star 14-ce0028TX. The darker the gray, the lower the brightness. If it is white, the brightness is relatively highest. We can see that the brightest part of the screen is in area 3, the biggest difference in brightness is in areas 7 and 8, and the one with the biggest brightness on the screen is 1 1%. On the whole, the brightness of the upper right area of the screen is higher, and the brightness of the lower left area is lower.
(5) Gamma curve
The significance of testing HP satellite 14-ce0028TX gamma curve is that gamma is the name of a nonlinear operation used for encoding and decoding in video/image. If the brightness coefficient curve of the display is close to the standard curve (at luminosity 2.2), it means that the display can correctly reset the screen brightness and contrast. The larger the deviation, the worse the display's ability to reset brightness and contrast. According to the test results, the brightness coefficient curve of HP Star 14-ce0028TX is close to the standard curve and performs well.
(6) Color temperature consistency
Next, the purpose of testing color temperature consistency is to test the stability of white point color temperature of display under different brightness. Users can adjust the brightness of the display at any time, and the contrast and color temperature should not change too much at this time. The screen brightness levels of HP Star 14-ce0028TX are set to 0%, 25%, 50%, 75% and 100% respectively. Test the brightness and chromaticity coordinates of all-white pictures and all-black pictures, and calculate the contrast and color temperature values. Under each brightness, the color temperature value and contrast should not change too much.
The white point color temperature of HP Star 14-ce0028TX has been kept at about 6900K, but the display effect is somewhat cold compared with the standard color temperature of 6500k ... In addition, from the brightness, it can be seen that the highest brightness of HP Star 14-ce0028TX screen is 182.4.
(7) Monitoring rating
The rating of the monitor is approximately equal to the rating of the whole screen performance by the fifth generation screen color calibrator of Datacolor Spyder5 Elite. Judging from the scoring situation, HP Star 14-ce0028TX performs well in contrast performance, color uniformity, color accuracy, tone response and so on, but the color gamut performance is poor.
Second, the real shot comparison
◇ Comparison of sample pictures: HP Star 14-ce0028TX and Samsung C27H7 1 1QEC monitors are connected through HDMI, and pictures are played in notebooks, and the pictures taken by Nikon D7200 are compared. From the comparison of the following seven groups of proofs, we can see that compared with Samsung C27H711QEC display 125%sRGB color gamut, HP Star 14-ce0028TX is not saturated enough.
◇ Light leakage contrast: I took a picture of (HP) Star 14-ce0028TX and Samsung C27H7 1 1QEC in a black background. The picture below is the actual impression, and it can be seen that both are well controlled.
After increasing the exposure, I can see that the light leakage point of HP star 14-ce0028TX is in the upper left corner, while the display screen of Samsung C27H7 1 1QEC is in the lower left corner.
First, introduce the configuration of the whole machine. Hp star14-ce0028tx adopts the common hardware configuration at present. The CPU is 8 generations of i5, 8G DDR4 memory,128g (SSD)+1TB (HDD), and the graphics card is MX 150(2G).
As the latest generation processor, i5 8250U is widely used in mid-range entry models of major brands, and U stands for low-voltage version. Compared with the previous generation upgraded to four cores and eight threads, the basic frequency is reduced and the turbo frequency is improved.
According to the theoretical calculation test of CPU-Z, the score of single thread is 338. 1, and the score of multi-thread is 1935.2.
The score of PCMark 10 is 3349, of which the score of common basic functions is 62 10, the score of productivity is 550 1, and the score of digital content creation is 2987.
HP Star 14-ce0028TX adopts the combination of 128G+ 1TB on the hard disk, which is also a common practice at present. According to the detection of CrystalDiskInfo, the SSD used as the system disk is SanDisk)X600, which is commendable.
As the HDD of the storage disk, Seagate ST 1000LM035 Cool Fish 1TB notebook hard disk is selected.
Test the reading and writing performance with ATTO disk benchmark, first of all, SSD, because the system disk is used more than half, and the speed may drop. The average reading speed of the measured current is 555.383MB/S, and the average writing speed is 471.974 MB/s/s.
Compared with SSD test rate, HDD is slightly slower, with the maximum reading speed of 140.787MB/S and the maximum writing speed of137.894 MB/s.
As for the graphics card, HP Star 14-ce0028TX adopts the combination of HD620 (nuclear display) +MX 150 (independent display). Among them, MX 150 is 2G video memory and full blood version. Although video memory will affect performance to some extent, the model and frequency of GPU are actually more important.
I used 3DMark 1 1 to test the graphics card. At the resolution of 1080P, other default settings score X 1635, and the performance is acceptable.
So what is the copying performance of HP Star 14-CE0028TX? First, let's look at the static heating. As can be seen from the figure below, the temperature of CPU is 50℃, the graphics card is 4 1℃, and the hard disk is 38℃.
Then I used Geeks3D FurMark's 10 minute copier to test. At this time, I saw that the temperature of CPU is 75℃, the graphics card is 74℃, and the hard disk is 50℃.
The noise caused by full-load heat dissipation is 6 1.4dB(A).
During this period, I also measured the temperatures in four key areas of ABCD of HP 14-CE0028TX with the help of infrared thermometer, and recorded them.
The temperature control performance of surface A is acceptable, and the temperature is mainly concentrated in the lower part, that is, near the rotating shaft.
The temperature of surface B is lower than that of surface A as a whole, but the central temperature will rise due to the heat of the screen.
The C-plane of HP 14-CE0028TX is consistent with the previous speculation. The opening of the audio bears part of the heat dissipation, and the median temperature is 50.5℃, and the overall right side temperature is higher than the left side.
However, the heating control of the D surface is acceptable, even at the air outlet, the highest temperature is 45.3℃, so it can be judged that the laptop has good heat dissipation, but it is worth noting that if it touches the keyboard surface during copying, the temperature of the right elbow will be higher.
After detailed performance testing, how can we get the scene experience of HP 14-CE0028TX?
First, the office scene.
The first is the office scene. We need to do a lot of text editing work every day, and the comfort of the keyboard can even determine the efficiency of the work. However, the performance of HP Star 14-CE0028TX is satisfactory, and the keyboard spacing and pressing force are just right. Whether it is slow pressing or stormy ravages, the keyboard performance remains the same.
When browsing the web with HP 14-CE0028TX, it is also quite smooth.
Without a mouse, when touching the touchpad, you can operate freely whether you zoom in or zoom out or slide up and down.
Second, the creation scene
As a productivity tool, notebook computer will naturally become a sharp weapon for me to process pictures and video materials. Thanks to the performance blessing of the 8th generation i5 processor, it is also handy to create with HP Star 14-CE0028TX.
Video:/v _ show/id _ xmzy1mzenzazmg = =. html？ SPM = a 1z3jc . 1 17 1 1052 . 0 . 0 & amp； isextonly= 1
Whether it is proofreading pictures or editing videos, it can play its due role. Although there will be some waiting when the finished products are exported, the overall processing efficiency is still satisfactory, and it is completely sufficient for daily raw material processing.

Second, the audio-visual scene
Audio-visual scene is definitely the advantage of HP Star 14-CE0028TX. I chose the 4K movie "The Source of Beauty Eating Roast Duck" to test it. From the video, we can see that the performance of this product is quite eye-catching, especially the sound effect part deserves attention. Compared with the Dell 7000 7572 I tested before, it is more stereoscopic and slightly better in resolution, which can bring a very good impression experience to users.
Video:/v _ show/id _ xmzy1mty3nzeng = =. html？ SPM = a 1z3jc . 1 17 1 1052 . 0 . 0 & amp； isextonly= 1
Third, the game scene
When I used Dell 7000 1605S before, because it was the nuclear display of HD620, playing a favorite game was basically an extravagant hope. Hp star 14-CE0028TX equipped with MX 150 is promising.
1. League of Legends
League of Legends has excellent overall picture quality at the resolution of 1080P, and there is basically no jam during the group war, so you can experience the game freely.
Video:/v _ show/id _ xmzy1mjy5mjq2ma = =. html？ SPM = a 1z3jc . 1 17 1 1052 . 0 . 0 & amp； isextonly= 1
After recording the data through Fraps, I extracted the count of 100 scale and plotted it in the table. We can see that the highest frame rate is 1 16 frames per second, the lowest is 40 frames per second, and the average is 73 frames per second, which is excellent.
2. Counter-terrorism elite: global offensive (CS:GO)
The experience of CS:GO default image quality 1080P is close to League of Legends. There is nothing to say about the experience, except that I haven't played with my food for a long time, and I haven't killed anyone in general. In Mr. Ma's words, how much do I take?
Video:/v _ show/id _ xmzy1mjgwmjg3mg = =. html？ SPM = a 1z3jc . 1 17 1 1052 . 0 . 0 & amp； isextonly= 1
According to the data recorded by Fraps, the maximum frame rate is 152 frames/sec, the minimum frame rate is 43 frames/sec, and the average frame rate is 65 frames/sec, which is not bad.
Fourth, maintain the scene.
Finally, I imposed a maintenance scenario, because I found that HP has built-in official online remote maintenance service, which is extremely convenient. First, after opening the software, you can choose the engineer you need or ask for help quickly.
Then the engineer will remotely control the computer to carry out maintenance according to your needs. For example, if I choose the activation of office, the engineer will also help you clean up the peripheral services such as the system, which is extremely intimate. This is definitely a plus item.
For the little whites who don't know enough about computers, it is very intimate and convenient to use this function to quickly find problems and solve doubts.
1. What about the industrial design of HP Star 14-CE0028TX laptop?
A: As far as industrial design is concerned, HP Star 14-CE0028TX notebook computer still inherits the good tradition of big manufacturers, and the clever design of three-sided wedge-shaped frame and escalator hinge is a bright spot. The long speaker opening can not only produce sound, but also dissipate heat. In terms of interface, the Type-C port has been added. If it is not enough, it would be better if both sides of HP Star 14-CE0028TX laptop are equipped with USB ports.
2. What is the internal structure of HP Star 14-CE0028TX notebook computer?
A: From the perspective of disassembly, the internal workmanship of HP Star 14-CE0028TX notebook computer is still relatively exquisite, and the selection of important components such as solid state, memory and hard disk is also a conscientious work.
