ASUS S400CA - a Windows 8 Touch screen Ultrabook
ASUS S400CA is priced arround only 699 U.S. dollars, plus it supports touch screen that represents the will be the cheapest on the market, this ultra-extreme of in a. Of the highlights of the aircraft in addition to its touch screen, durable battery, the metal surface and the clean design quality speakers.
Quality and Design
S400CA The design is very simple. The silver aluminum shelved the wrist with black Uncovery and bottom of the fuselage comfortable contrast. The four corners of the handle rounded moderate.
The overall quality of the machine belonging to the upper level, the hardness of the fuselage enough to resist a part of the external force. The especially strong Uncovery, and compared to the other we’ve tested this ultra-extreme feeling better able to withstand external forces. The overall workmanship is not bad compared with other ultra-extreme Benxiang basically the same.
It is noteworthy that the aluminum material on the S400CA only as decorative, although it does provide a certain amount of the supporting force, but it is not the fuselage of the sources of the primary supporting force. For this price, the notebook, all-aluminum body is still too expensive.
S400CA design is not to design around the user’s scalability, but it can still manually by the user hardware upgrades; eight screws unscrew the bottom of the fuselage, you can see its 2.5-inch hard drives, mSATA interpolation slot, wireless card and a free memory slot. For over most of this, which is not bad.
Enter the input interface
S400CA port is also provided one of the highlights: it provides many other ultra-extreme interface, including a VGA port, an Ethernet interface, a card reader and full-size HDMI output interface; addition there are three USB ports (one USB 3.0 interface, two USB 2.0 ports). The small details in S400CA body I particularly like is that it several system status indicator on the front edge. I use a laptop, do not see the hard disk light is flashing always feel lack something.

Keyboard and touchpad
S400CA has a full-size keyboard keys like a MacBook as. It is not the favorite part of me S400CA body. Like most of this ultra-extreme, this keyboard to press down the obvious sense of feedback, but this does not feel at ease. Its short key process also affects the feel of the feedback.
One thing I do not like is its body when typing jitter, this feeling is completely unacceptable, and it appears very high frequency. Lastly dissatisfaction is the key surface granular matte plastic, which means that after prolonged use some of the buttons will be worn becomes smooth.
ASUS touchpad no dedicated left and right click buttons, press opinions on the equivalent of a left mouse click anywhere. Its surface is very smooth and comfortable, and click when the sound is not great, but the advantages that’s about it. The whole surface of the clickable does not seem to be properly supported good, so at certain times to click feel when the whole pad is in the jitter. In addition, one-click operation really strenuous. Whole, Asus can be obtained in this regard a better score, but unfortunately they did not do a better job.
Screen and speakers
Its 14-inch screen is another sore spot S400CA. It attractive, of course is the touch function, it works without any problems, and it attracts at only say that it is a novelty for us, nothing more. Not let the screen so that the touch features the biggest problem is that the hardness of its availability, the screen hinge enough to make you during touch operation down, but it will still use the back and forth, which makes the whole experience very bad. In the end, I found that I was with one hand supporting the screen, the other a hand touch operation is in progress.
The performance of the screen there is no remarkable place. Its resolution is the lowest, the mainstream PC only 1366×768; compared with the higher resolution of the screen (e.g. 1920×1080 of the screen), it grainy very strong, this is because of the larger size of its physical pixel, The number of pixels per square inch is also less. Windows 8 zoom size in different resolutions is now very modest, at high resolution, the font is too small for this reason no longer exists, the only reason to use such a low-resolution screen only cost savings.
Make matters worse, in the resolution of problems is to restore the degree of screen image, contrast, saturation worse than the general screen. The color of the entire screen looks a bit gray feeling, and the viewing angle is also very low; optimal viewing angle of only about 10 to 15 degrees, more than this perspective, whether it is down from the top or from the screen on like cast a layer of ash. The brightness of the screen is also less than ideal.
Speaker is a small step forward for ordinary puny laptop speakers. Its own pseudo surround sound is actually still in very good shape. The speaker volume is adequate, but the slight lack of performance in the bass. Under normal circumstances, I would suggest you use headphones to listen to music, but a little background noise S400CA headphone jack output.
Our evaluation the Asus S400CA-DH51T Touch over most of this configuration is as follows:
- 14-inch touch screen (1366×768 resolution)
- Windows 8 64-bit operating system
- Intel Core i5-3317U dual-core processor (1.7GHz frequency, dynamic overclocking up to 2.6GHz, 3MB L3 cache, 17W TDP)
- Integrated Intel HD series graphics chips
- 4GB DDR3-1600 memory (supports up to 8GB, 4GB the preloaded memory plus a free memory slot)
- 500GB 5400 rpm hard drive the (Seagate ST500LT012, thickness 7 mm)
- The 24GB SanDisk i100 solid state hard disk cache
- Qualcomm Atheros AR9485WB-EB Wireless LAN
- Integrated Bluetooth 4.0
- Built-in high-definition camera
- No built-in optical drive
- One-year warranty
- 44 watt-hour lithium-polymer battery
- Weight: 1.8 kg
- Size: 34 x 24 x 2.1 cm
- Price: $ 699
Such as S400CA entry-level super pole This is the most common configuration. Deadline date, S400CA only above a configuration is optional. The 500GB hard drive is worth mentioning, because usually ultra-extreme are equipped with a solid state drive. The advantage of mechanical hard disk storage space, general super pole of the maximum capacity of the solid-state drive is only 256GB. Its disadvantage is performance in reading data than solid-state drive to be much slower, everything related to disk operation will be affected: for example, boot, open the program. Solid state drive speed to be at least 20 times faster than mechanical hard.
The low performance of the mechanical hard part to be compensated by the machine’s 24GB solid-state hard drive cache. Although not allowed it in the end how much performance boost, but for sure there is a mechanical hard drive is better than light.
In addition to these, in daily use among S400CA configuration is sufficient to meet, including web browsing and document processing. Intel Core i5 dual-core processor with powerful processing capabilities, 4GB of memory sufficient to meet half of the multi-tasking. S400CA or all over most of this most are not good of course, is 3D gaming, integrated graphics simply can not meet their needs.

Heat and noise
Has a small fan in the rear of the fuselage, which is hidden behind the screen hinge. Overall, I prefer notebook capable of directly out of the exhaust air, rather than through other parts of the reflected, but the cooling effect of the S400CA not let me complain too much. Pressure test temperature only just over a little room temperature, the fan is very quiet no noise.
S400CA can do it is to use battery-powered. We use Powermark balanced power mode, the battery life of the timing, the middle of the operation including automatic web browsing operations, document processing, gaming and video playback. This compared to battery testing we do before higher demands, but also closer to the time when the real use.
Length Powermark battery test results (the higher the score, the better):
The ASUS S400CA Touch over most of this to the test using the lithium polymer battery when it is 44 watts stays of 3 hours 51 minutes (in the old battery test, which means it can sustain the last 6-7 hours). This time for a 14-inch ultra-extreme it was quite impressive.
The ASUS S400CA Touch over most of this ultra-extreme from the surface is a good choice: as long as the $ 699 can buy a support for the touch screen, running Windows 8, beautiful design and battery life lasting. It also has a relatively select interface, good quality and good speaker. It gives you the most important satisfaction user experience.
Touch screen with no major problems, but for a laptop, this can only be regarded as people feel something novel; most annoying is that the screen is constantly shaking when you use the touch screen. The quality of the screen is simply awful; viewing angle, low resolution color reproduction is poor. Keyboard giving the impression of a very general, and the body will appear when typing jitter; the touchpad making will also clicked jitter. The headphone jack will have background noise, which is obviously not a good thing. Finally, its performance is less than satisfactory, mechanical hard disk has brought us more storage space, but sacrificing too much performance.
We recommend that the priority in the purchase of better quality screen computers, and really do not want to spend too much money, perhaps we will give you recommend S400CA. It’s the overall quality is not long enough as the recommended choice.
- Good battery life
- Good speaker
- Low prices
- Bad screen
- Feel like a general keyboard and touchpad
- Low-performance mechanical hard disk
- Headphone jack background noise
