I. Introduction

Buy laptops, there are generally two directions (as a traditional science and engineering straight male), one is performance, the second is portable, before the beginning of college, the pursuit of the ultimate performance, after a blue sky to catch the book, 170em to 770zm. When used in the dormitory, it must be very cool, 17.3-inch screen, powerful graphics performance and processor performance, superior expansion capabilities, but at the same time a few ten pounds of mobile weight, so that every move has become a torment. In order to protect the effect of the shoulder bag, an alien bag is used. The simple bag weighs more than 2 kg. Every time you carry it back, you will doubt the life.

Later, I slowly discovered that in fact, I do not need such a powerful performance at all times. Sometimes I just type a word, go online, watch a video, put a ppt, then start the ThinkPad X230, a 12.3-inch screen. Or ips, excellent keyboard feel, easy to use little red dot, as well as this volume is relatively more powerful expansion performance (dual channel memory, mSATA + SATA3.0, 3 * USB can also expand, card reader, VGA and Mini DP), as well as 3 generations of standard processor, have fairly good processor performance (toothpaste plant generation performance improvement is very small for each generation of the same frequency, but 4 generations start, mobile processor frequency is very low), daily use ThinkPad X230 mobile is also very comfortable, said to go away, sex can use

Later, it was discovered that in terms of portability and performance, it seems that there is quality. This also makes the millet notebook into the field of vision, good appearance, good configuration, beautiful all-metal body, excellent screen and sound effects (screen with the price level, audio level), for a time to make the mushroom heart water, but There is no reason for a change

However, when the performance of a portable notebook is not the same, the price came to 10,000 yuan, that is, Dell's XPS, ThinkPad's X series, Apple and HP's Elitebook (This is a number of used, reputation is really ...)

What kind of experience will this notebook have? Is it worth the price? Is it worth the price? Is it worth the price design? Let's take a look at the performance of HP's Elitebook in all aspects: performance, temperature, volume, weight, texture, and workmanship.

Speaking of this notebook's way, is the friend company's new computer, from the ThinkPad's old X series, replaced by the current HP's Elitebook series, the system, permissions are done, the performance test is carried out within a limited range Everyone sees a lot of dry goods.

Second, HP Elitebook business thin and light notebook 820 G3 accessories shoulder bag

â–¼ When the computer is in hand, it is placed inside this HP's shoulder bag. The texture of the shoulder bag is good.

â–¼ There is a small HP logo in the lower right corner, still an art standard

The zipper's feel and texture are good, smooth and tight

The straps behind the ▼ are also very wide, not Le, behind there is a large area of ​​this design breathable

â–¼ There is a rear strap on the back of the double shoulder strap. It can be used to fix the bag on the trolley case.

â–¼ The top part of the mobile part of the cortex package, feel good

â–¼ After opening, the interior space is very spacious, there are also a lot of pockets, the protection of the notebook is also very thick

â–¼HP official accessories, shoulder bags can also be warranty and technical support, haha

Third, HP Elitebook business thin and light notebook 820 G3 appearance size

â–¼ At first glance, the shape of this notebook is familiar, but the overall feeling is very rounded

â–¼In the middle of the iconic Hewlett-Packard LOGO, any change LOGO, no sense of violation

â–¼ The corners of the notebook have a relatively large arc, and the side part also has a chamfer. The surface of the A-side aluminum alloy is moderately sandblasted and not very delicate, but it does not touch the surface particles.

â–¼ The notebook is very small, slightly larger than the ipad air2, whether it is single-handed or used, it is very convenient

â–¼ After opening, the first feeling is very good, the border is black praise, there is friction in the middle of non-woven

â–¼ After removing the non-woven fabric, I still feel pretty, black and white

â–¼ On the top part of the B side, there is a slightly raised convenient to open the design of the notebook

â–¼In addition, this notebook is open without pressure with one hand, damping is great

â–¼ But this border is particularly wide, the material is still plastic. There is a rubber pad around, which can not only protect the screen from shock, but also prevent shock and friction between B and C sides. There is also a line of English below, which is the full name of the famous B&O, indicating that this audio is still a source of

â–¼The top of the B plane is the camera in the middle and there are three holes next to it. It should be a camera indicator with two microphones. The array microphone can achieve certain noise reduction through the algorithm.

â–¼ The width of the border is really powerless Tucao, side width 15.51mm

â–¼ top width 26.86mm, haha, real hit border race

â–¼ matte screen, resolution 768P, display effect can also be

â–¼ familiar HP LOGO at the bottom, in addition the bottom border is also very wide

â–¼C surface, also the material of aluminum alloy, with a black keyboard

â–¼Power button is a good feeling of aluminum alloy

Above the C side is a long strip of B&O speakers. The texture of the aluminum alloy filter is good, and the gap is very uniform and small. In addition, the rotating shaft is a sinking shaft

â–¼ The keyboard is black, feel good, but each key surface has no arc ergonomic design, the keyboard feels up and down

â–¼ Key process can also be, visually measured in about 2mm, is the keyboard feel of ordinary portable notebook, this is definitely better than mac air, but certainly not comparable with x230

â–¼ haha, you see what this is, black spots! This is very interesting, this is a tribute to the ThinkPad? However, this design, which does not need to be moved, can complete the mouse operation and is convenient when used outdoors.

â–¼Then this will be sent ThinkPad shoulder bag in the Jingdong to buy HP Elitebook business thin notebook, haha

â–¼The touchpad is a four-button up and down design, two keys, two keys, the middle of the touch part should have a layer of glass

â–¼ HP's this Elitebook machine has chamfering on almost all sides, but there is no ... after pressing the button, if you go up, you can feel the sharp edge of the aluminum alloy

â–¼ There is no chamfer on the side of the trackpad. And this touchpad is underneath the aluminum alloy C surface, with a gap in the middle, it feels easy to filth.

â–¼ The lower left corner is still familiar with the Elitebook logo

â–¼ The lower right corner is the familiar HP small arrow keys, feel bad. Below is the fingerprint, next to the logo of i7 and Ubantu

â–¼ The side of the feeling is still very thin

Fourth, HP Elitebook business thin notebook 820 G3 expand performance

â–¼ There are four indicators in the lower left corner, wifi, power, charging and hard disk indicators

â–¼ Measure the thickness of the notebook at 20.42mm

â–¼The side ports, from left to right, are keyholes, air outlets, VGA (socket, so old), USB3.0 (rechargeable), SC card reader (Smart Card)

â–¼ The other side, from left to right, is the Type-C interface, DP interface, headphone jack, USB3.0, RJ45, expansion dock slot, SIM card slot, and power interface.

哎 哎 我 哎 哎 哎 哎 哎 哎 哎 哎 我 哎 我 我 我 我 我 我 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎 哎Then flipped the notebook over and saw the familiar SD card slot

â–¼In addition, this card slot is not a traditional buckle design, but can be pulled out directly

â–¼ D surface I think it is black plastic, is to know to touch or metal, feel good

â–¼D face has a large arc of curvature, the front is a flat mat

Behind the raised pad

â–¼ There are familiar limit holes and contacts behind the back pads

â–¼On the other side, it should be the contact point for notebook power supply

â–¼ through the bottom of the metal mesh, you can clearly see the inside of the dual-channel memory, and is still replaceable design

â–¼ Then found a flaw, in the RJ45 connector plastic cover part, the gap is obviously uneven

â–¼ The rubber plug at the rear screw hole is also exposed

V. Performance and Configuration of HP Elitebook Business Thin and Light Notebook 820 G3

â–¼ boot, I will not say everywhere, they are still using win7 system, the screen's first look is very good, matte screen is comfortable

The processor is the i7 6500U, 2.5G frequency, the graphics card is nuclear, HD G520. Haha, ancient configuration

â–¼ Due to lack of permissions, there are other reasons why the computer cannot install programs. It's easy to use a card to test hard. In other words, a nuclear card is a tool that is hard enough. First look at the overall configuration. I7+ dual channel memory, 256G solid state, and AUO's 12.7 inch screen

â–¼6 generation low-voltage i7 processor, TDP in 15W, dual-core four threads,

â–¼ DDR4 dual channel memory. Yeah, how about dual-channel 2T. In addition, whether it is H or U, their memory controller modules are being castrated. Many of the modified i7 processors do not support quad-memory, but the same model QM-terminated i7 processor is only four memory.

â–¼ The memory is magnesium, the frequency is 2400, the production date is still very new, the 42nd week of 17 years

â–¼ CPU-z test under the cpu performance, and 4790k compared to single-core performance of about 80.2%, multi-core performance for its 36.32%, the gap is still very large. After all, the positioning gap is also great

â–¼ chess, multi-core 5649, this point is slightly lower, normal 6500U should be around 6100

I7 6500U comes with a nuclear display, with 24 EU, the highest core frequency of 1050MHz, play a lol slightly smooth look

The 256GB solid state is Intel's, SATA interface, using Intel's ahci driver, but 4K is not aligned. I guess doing 4K alignment when doing the system will greatly affect the 4K performance of the SSD

â–¼ test, continuous write and read performance can also be, 4K performance is indeed very poor, only more than 500 points

â–¼ look at the solid state hard disk information

â–¼ use AIDA64 to see the computer's configuration

â–¼ By the way, test the performance of the dual-channel memory, the processor is i7 6500U, dual-channel DDR4 2400MHz, writes and reads looks like 28000MB/s to 29700MB/s, delay is 68.9ns

Sixth, HP Elitebook business thin and light notebook 820 G3 cooling capacity and body temperature test

▼ copy the FPU, the processor frequency is maintained at the quad-core 2.7GHz, about 5 minutes single copy, the processor is not down-clocked, the temperature is around 63 °C

▼The temperature at the air outlet rises, it is about 36°C, then it is stable, it will not rise again

▼ The temperature of the metal part above the air outlet is 27.4°C.

▼ Keyboard left side temperature 23.4°C

▼ Keyboard middle temperature 23.2°C

▼ The temperature on the right side of the keyboard is 20.1°C. The farther away from the air outlet, the lower the keyboard temperature is.

▼The temperature of the left palm rest is 19.4°C, which is very small compared to the temperature rise before roast chicken

▼ Right palm rest at 18.5°C

▼ touchpad temperature is about 17.5 °C, are not high

â–¼ stop single copy fpu, processor temperature drops quickly, thermal module efficiency is high

▼The outlet temperature drops quickly to 31.4°C

The last stable at 24.5 °C, the temperature slightly improved compared to the roast chicken, but the amplitude is very small, indicating that the cooling effect of this notebook cooling module is good, almost no heat accumulation

Seven, HP Elitebook business thin and light notebook 820 G3 USB3.0 and Type-C interface speed test

â–¼ U disk is SanDisk CZ73 32GB, look at the read and write speed

â–¼Change a USB 3.0 Type-C mechanical hard disk drive, USB3.0 connection, read 110, write 102

â–¼Change to Type-C interface, read 100, write 99, almost same

â–¼ Use the Type-C interface to charge the millet 6, does not support the PD fast charge, can only slow charge, the power supply is still relatively weak, 1A current and voltage dropped to about 4.9V. In addition, it is not recommended to use the USB 3.0 interface of the notebook to charge the mobile phone, ipad or other devices.

Eighth, HP Elitebook business thin and light notebook 820 G3 weight and mobile weight test

â–¼The weight of the notebook is about 1247g, very light

â–¼With power, the weight came to 1658g, very heavy, this power pit father's

â–¼This 65W power is 412g bare, heavy, and bulky

â–¼ NetEase's 65W PD power supply is only 188g

â–¼ Not to mention volume comparison, from left to right once is the NetEase 65W PD power supply, millet 6, HP comes with 65W power supply

Nine, HP Elitebook business thin and light notebook 820 G3 screen display effect

â–¼A6300 real shot, only correction lens, without any late

â–¼Viewing angle, there is no problem on the right

â–¼There is no problem on the left

â–¼There is a problem on the upper side and you can hardly see it

X. HP Elitebook Business Lightweight Notebook 820 G3 Speaker

â–¼ The effect of the speaker is still very good, better than the average notebook, parsing and high-pitched sound, the sound field is also good, after all, B & O

â–¼ In addition, this sound is good at the upper part of the C-surface, everyday songs and the like, and there is no question of directivity.

Eleven, HP Elitebook business thin and light notebook 820 G3 keyboard backlight

â–¼ notebook comes with a keyboard backlight, there are two files, the effect can be

â–¼Basic typing is enough, you can clearly see the keyboard letters

â–¼In addition this keyboard backlight has two files

â–¼ backlight off

â–¼ Backlight

â–¼ second gear backlight

Twelve, summary

1, in the high-end thin business, many people's eyes are on the XPS, ThinkPad X series, Sophie or Mac, almost no one would think of HP's Elitebook, but the performance of HP's Elitebook is still very good

2, all metal body, whether it is work or feel, are very good, in addition to the touch pad part is not chamfered, the overall body of the notebook touch is very good, each part of the feel is very delicate, is a bit cool

3, notebook body function and interface is still very comprehensive, small black spots, fingerprints, VGA, two USB, Type-C, etc., daily use is fully enough, and there are SD card slot, SIM card slot, these are Is the highlight

4, as a light and thin business, weight, volume control are very good, and performance, heat is very good, dual-channel DDR4 2400, single copy FPU processor has been full of Rui frequency, temperature is about 60 °C, palm rest And keyboard temperature control is very good

5. The only thing I can't understand is why I still use an ordinary notebook power supply. It is not OK to choose a PD charger. Whether it is volume, charging speed, or compatibility, it is better. I will add a Type to the power interface. -C, isn't it a better thing?

thank you all!
