I have long thought to replace the old laptop is Lenovo, which is used by children. Though he is powerful enough (Core i5, 8 GB of RAM, SSD), but the display matrix he TN with poor viewing angles and low resolution, noisy cooling system, short battery life. Power is, in fact, superfluous, since run mostly it just a browser, text editor, and watch videos on YouTube. And now the company produces beautiful netbook CHUWI LapBook. Screen 15 “IPS with a resolution of 1920×1080, Atom x5-Z8300 with passive cooling, 4 GB of RAM, 64 GB eMMC, capacious battery For me it was the ideal candidate to replace – just a dream, given the cost, of course, I ordered it -. With the Point, It came just $ 170. The image of the ideal netbook remained in dreams … but first things first.
EQUIPMENT
CHUWI LapBook comes in a cardboard box.
On the box glued sticker with the specifications.
Inside: netbook, power supply, power cord, quick tutorial (including in English), warranty card.
APPEARANCE
Power supply 5 V / 3 A European plug and USB port. USB> DC (3,5×1,35 mm) Complete cable has a length of about 1.5 meters.
The case of the netbook CHUWI LapBook is made of pure white matte plastic, which does not remain fingerprints, a black frame around the display. It looks just great netbook. The quality of the assembly perfect – nothing is loose, do not fasten and groans.Measured size: 370 x 240 x 17-21,5 mm. Weight 1.9 kg.
The top cover of the logo suffered CHUWI LapBook.
The bottom has rubberized feet. There are slots for speakers.
Caps screws do not stick out.
On the left side are DC power port, USB 3.0 port, and mini-HDMI. Next to the DC port has a LED that lights when the power is connected.
On the right side: port USB 2.0, headphone output, a slot for micro-SD card.
Closes netbook CHUWI LapBook tightly.
The maximum level of the opening display of about 135 °. The hinges are quite stiff.
The frame around the display is not very wide. If you look closely, you can see that the right frame is wider left. What is the reason, I do not know. The eye does not rush and do not affect the comfort of work.
Above in the center is the camera lens.
Above the keyboard are operation indicator, Caps Lock indicator, Num Lock indicator 2 Microphone hole.
The appearance of a great and makes you want to use the netbook.
UEFI AND INSTALLED ON WINDOWS OS
In CHUWI LapBook uses UEFI Option from American Megatrends with a text interface.
Engineering menu completely open access to all possible settings. Be very careful with these settings, engineering, as some of them are stored in non-volatile memory, turn LapBook in the “brick” simple.
The UEFI no module CSM (Compatibility Support Module), ie You can not use operating systems with Legacy leaders directly, only UEFI x64.
On CHUWI LapBook preinstalled licensed system Windows 10 Home with English interface. You can easily switch to Russian.When you connect to the Internet system is being activated.
Necessarily it is necessary to install all available updates (this is quite a long process). Then turn off the auto-update system and a built-in Windows Defender antivirus. After that, the Atom processor will breathe freely.
After installing all updates and cleaning you 40 GB will be available on the internal eMMC storage.
SUPPORT FOR ANDROID AND LINUX
Distribution Linux Ubuntu 16.10 has started. It did not work Wi-Fi and audio controller. But everything else seems to be working.
Remix OS 3.0.206 (Android to the x86, supported Android-x86 Project community), which are equipped with much Chinese on the device: Atom, does not work.
COOLING
In recent years, Chinese companies have proven that they know how to make laptops with the perfect passive cooling system.
In CHUWI LapBook also uses a passive cooling system.
When they began to appear on the device Atom x5 / x7, it turned out that it is very hot of SoC, and the producers (mostly Chinese) spit on the normal cooling system – CPU throttling went in for a minute, even in mini-computers, where it should not be. Naturally, this caused “unnecessary” questions from users. For the definition of throttling meets certain register MSR. Intel entered slyly – DPTF starts tightly control the frequency, a number of cores, the omission is that, etc. In this case throttling never exhibited (the program is not informed of throttling), which created a sense of stable operation and high-quality cooling, but in fact it is not. Some analysts still do not know this and warn that in such a device, no throttling, based only on data throttling, that is not true.
Throttling – it is normal for tablets and laptops. But it should be in moderation.
Without load, SoC temperature is at 45 – 55 ºC. The body barely warm.
LINX (LINPACK)
This is one of the main CPU stress test, which can turn the processor in the pan. 1 GB of memory was allocated for the test. In an ideal situation, the frequency of all cores should be 1.6 GHz all along the test.
Within a few minutes, the temperature reached 83 ºC and began throttling – rate began to decline nuclei. For 10 minutes the frequency has reached the minimum level of 480 MHz and jumped in the range of 480 to 1 GHz. For 30 minutes, the situation has not changed. All the same temperature of 83 ºC, is the same range of 480 to 1 GHz.
This is bad. Then test the cooling system (with the load on the GPU) makes no sense, it is implemented poorly.
It revealed yet another unpleasant feature. When connecting an external heat supply increases and throttling occurs instantly. Apparently, the power controller SoC and a cooling plate. Power controller accelerates warming SoC.
If you work for this netbook CHUWI LapBook, it is better to work without external power and charge the battery when the notebook is not in use. About any games on this netbook should be forgotten immediately.
I wanted to remove the bottom cover to look at CHUWI engineers, but it was not easy. Not to unscrew the screws inside the cover has some fixing (can be thermo-adhesive tape) and just can not be removed. Disassemble the power did not.
DISPLAY
The netbook CHUWI LapBook uses panel15,6″ with ID BOE0687, 1920×1080 resolution, matte finish. Initially, CHUWI stated that LapBook used IPS matrix. This was based advertising messages, IPS stated on the box, IPS is still stated on the website. But as soon as real users are receiving LapBook, there were some questions. spokesman CHUWI on 4PDA acknowledged that the matrix is not the IPS.
Highlighting quite uniform. There is little glare, but her eyes are almost invisible. Reserve brightness not. Contrast is low.
As can be seen, in CHUWI LapBook used matrix TN. The viewing angles are appropriate. Horizontal viewing angles are still more or less, but the vertical viewing angles all bad – suffering black level, contrast, color inversion occurs.
INPUT DEVICES
In CHUWI LapBook excellent keyboard. In the center of flex slightly. The buttons do not “ring”, the middle course. To set the text fits perfectly. The keyboard layout is applied only to the English.
Some people may not like the power button next to Backspace. I’m working on a laptop similar to the location of the power button, I’m used to and never misses.
If you look closely, you will not see on the keyboard brightness control function keys! For the first time, I see this on a laptop. Those. the brightness will have to adjust to the OS. After working for CHUWI LapBook, I realized that these buttons are simply not needed. The display does not reserve the brightness and you will most likely always be to work only at 100% brightness of the display.
The touchpad is large in CHUWI LapBook from a Chinese company Gilead. No third-party driver is not present, the device operates as a standard HID. Work comfortable with it, just have to get used to the sensitivity (eg, single-touch requires a little more effort than a light touch). It supports multi-touch. Practice gestures on touch 3. Because no software to configure the touchpad from the manufacturer, you have to change some settings in the registry. For example, through the registry, you can change the direction of scrolling.
BUILT-IN CAMERA AND SOUND
Built-in speakers – this is the saddest after the display, that is, on this netbook. The sound worse, I do not even have seen the plates. I do not even know how to describe it. Low volume, the sound is clamped, with a frequency range of mess, there are obvious noises. With such a sound view of any comedy turns in watching the drama! In general, then save only the headphones – everything a lot better with them.
Stated that CHUWI LapBook a 2-megapixel camera. In reality, 0.3 MP. Use the module from Feiya Technology. The maximum video resolution of 640×480 at 30 f / s, but in reality there are 20 frames and 360p. Basically, the camera is not so bad, I’ve seen worse. Little noise, “soap” is not so much the number of frames is independent of the lighting. Even in total darkness, illuminating a display, good camera “sees” the face and silhouette.
PERFORMANCE
I am one of those who believes that Atom – a great processor for their tasks. I had a different device on the Atom, including myself for a long time enjoyed the TV box with Atom. He has a good performance in one important condition – the cooling system must be perfect, and the processor must not throttling. But as you already know, Z8300 in CHUWI LapBook throttling at every opportunity, as netbook bad cooling system. Furthermore, even stronger throttling processor when connected to external power (due to the fact that the power share controller cooling system SoC).
The surprise caused the fact that the memory frequency in LapBook all 1066 instead of the “regular” 1600 MHz for most devices on the Atom. The UEFI I changed the memory settings to Auto.
Remember, I wrote that with engineering UEFI settings, be careful, change only what you know. So, my CHUWI LapBook after the frequency change to Auto has become a “brick”, was not included, and on what does not react. After 5 minutes, he has involved himself. In this case, the memory frequency setting in UEFI back to 1066. I braced himself for the second time, and do not put the Auto, and 1600 MHz. Again he received a “brick”. After 5 minutes, the computer came to life, the frequency back to 1066. I no longer experimenting, well, it …
I will give the test results when LapBook not connected to the charger, ie It is running on battery power. After each test, I made a break of 20 minutes. Keep in mind that these results would apply only to LapBook, and not to the SoC Atom x5-Z8300, as throttling leads to unpredictable results spread.
In CHUWI LapBook in the form of internal storage used eMMC Samsung CJNB4R 64GB. The same chip is used, for example, Lenovo Yoga Book.
The rate is at a very good level among Atom-devices.
The netbook CHUWI LapBook has a slot for microSD memory cards. The SoC Atom is already integrated controller for the SD card, but CHUWI decided not to use it and found an additional controller Realtek. I have a UHS-I microSD card, which gives a linear speed of 85 (read) / 20 (entry) MB / s. The test will be using it.
No problem, the speed limit is on the cards as possible.
Connecting an external 2,5″ USB-drive caused no problems. The food was missing.
PERFORMANCE NETWORK INTERFACES
In CHUWI LapBook using Wi-Fi adapter Realtek RTL8723BS, fairly widespread and budget solution. It supports 802.11n standard 2.4 GHz and MIMO 1×1.
Wi-Fi connection keeps confidently. Position netbook speed slightly affected.
For testing, I will use perf, which will show the real speed. CHUWI LapBook is 5 meters from the router through a reinforced concrete wall. At this point most of my 802.11n devices (MIMO 1×1) to show the speed of 50/50 Mbit / s. Laptop with MIMO 2×2 about 80/80 Mbit / s. Smartphones with MIMO 2×2 also about 80/80 Mbit / s. Stationary computer with MIMO 3×3 at 5 GHz, then (if it is placed next) squeezes around 100/100 Mbit / s. All this is a real data transfer rate (measured perf), rather than the connection speed.
51 Mbit / s and impact, and on reception. Claims to the quality of Wi-Fi and I have no speed.
VIDEO PLAYBACK
I think there is no point in detail to test support hardware decoders Atom x5 / x7. All this is well known and tested a million times. I will say briefly, the hardware decoder is able to decode:
H.264 up to 4K with any bitrateHEVC / H.265 up to 4K with any bitrate
NEVC Main10 (10-bit) does not support software decode without the mules can not.
NEVC Main10 (10-bit) does not support software decode without the mules can not.
But playing 1080p60 video on YouTube in different browsers will test.
We tested the CPU load and smoothness (visual) while playing 1080p60 content in different browsers. The test will involve Microsoft Edge, Mozilla Firefox, and Google Chrome. All with the default settings. YouTube site uses HTML5 by default.
For the dough will use this video 1080p60.
MICROSOFT EDGE
CPU utilization to 40%, using hardware acceleration. CPU frequency is kept at 460 – 800 MHz. The video plays smoothly.
FIREFOX
CPU utilization of about 30%, using hardware acceleration. CPU frequency is kept at a minimum of 460 MHz. The video plays smoothly.
CHROME
Used software decoding VP9. CPU usage by 100%. Processor Speed max. Watch the video can not be normal. When switching to 1080p video played smoothly, loading drops to 50%.
BATTERY LIFE AND CHARGE
The netbook CHUWI LapBook comes with the power adapter with a USB 5 V / 3 A.
Memory connected via a DC connector 3,5×1,35mm. The regular power supply is not instilled confidence in me. I did not understand, but it is very easy and during operation is heated to 60 ° C. If necessary, you can use any USB memory that supports current 3 A, which I did. At the peak of the tester, netbook consumes 2.8 A.
The netbook CHUWI LapBook without any problems and being charged with an external battery.
The netbook CHUWI LapBook has a built-in battery capacity of 10,000 mAh (with voltage up to 4.2 V). Charging the battery for a long time.Full charging time – 6 hours 20 minutes.
To test the brightness of the display was set to 100%. Two tests were carried out before the blackout. Continuous playback of 1080p video on YouTube and web browsing: use standard browser Edge, unwrapped the whole screen; every 60 seconds a script causes the browser to load a new website (s wide variety).
YouTube: 7 hours 10 minutes.
Browse websites: 6 hours 30 minutes.
Browse websites: 6 hours 30 minutes.
The battery life is excellent for a device with a screen 15″.
CONCLUSION
The netbook CHUWI LapBook could not replace my laptop Lenovo. Change TN TN matrix, and, albeit noisy, quiet cooling system, but with a throttling, there is no point. But someone this netbook is quite suitable as a typewriter and to view Web sites. Enumerating the major pros and cons of this netbook
