When most of the heat accumulation in the cooling vents near the location, and other parts of the temperature not higher than 40 ℃, it can determine the cooling system design is reasonable. From the temperature distribution above, most of the keyboard parts of the heat is concentrated in the left position, right of the keyboard and touchpad, wrist support part almost no heat distribution, so that users in the use of ProBook 430, the left hand will feel hot. In addition, from the core temperature, high load at about 75 ℃, performance in the mainstream standard.

In the power supply the power button left in a "ECO" key energy-saving button, next to also have 4 state indicating lamp, convenient operation state. At the same time on the C surface edge with oblique plane exquisite workmanship, cutting surface, and also feel more remarkable fingers, there will be no discomfort.

The performance, we were tested by Cinebench R15 software, multi thread test scores for 247cb, single thread performance of 108cb, test score was low, but belong to the normal level.

At the back of the fuselage heat concentrated near the right side fan area, the maximum temperature of 50 degrees, the temperature of other regions are relatively low. In general, the metal material in the body benefit, HP ProBook 470 G2 is in the heat's acceptance, out in the office environment is basically don't have to worry about the problem of heat dissipation.

Battery Type: Li-Polymer Voltage: 11.1V Capacity: 44Wh / 6Cell Weight: 310g Size: 281.00 x 103.00 x 11.10 mm Color: Black

We end by a now game performance is the most fiery network game "legend" -- furnace slag on the laptop for a test, and "legend" furnace slag can support touch screen, touch screen on the HP 470 also provides a good test environment.

HP ProBook 440 using a UHD screen is the most important feature of the super high resolution, so the card furnace stone more delicate, especially in the curse of Naxxramas slants dark scene, through the laptop screen can feel more obvious, gloomy scene dynamic effect and hold gold card performance force to obtain the very big promotion.

SYSmark 2012 is the latest BAPCo benchmark, it brings many properties of new graphical user interface, a separate test execution and strengthen the internal configuration management, performance reflect such as office efficiency, data analysis, system management, media creation, 3D modeling and web page development system, suitable for corporate users as reference.

Graphics cards, in addition to the core i3-4010U low voltage processor with HD Graphics 4400, the machine is also equipped with Radeo HD 8670M graphics card, by testing the Entry model 3DMark Vantage, finally can get 16790 points, compared with the HD Graphics 4400 graphics display performance to a higher.

Lenovo Yang days V4400 the 48Wh lithium battery, through the PowerMark software test, we can see the 8 hours and 6 minutes endurance performance, performance is quite good. In general, the business notebook endurance is worthy of praise, the actual use can be more than 4 hours of continuous work support.

Considering the user to extend the notebook in need of life, the power management settings for the power saving mode, so we before testing is provided, also banned laptop automatically reduce the brightness after a period of time, prohibit closing the screen backlight, prohibit automatic sleep. At the same time, we let the WiFi remains in the open state, so as to simulate user's real state.

The keyboard surface temperature on cooling air outlet near the central region, the keyboard than other location slightly high, high work load, if often struck the central area of the button, there will be heat transfer, the typing comfort has certain influence. In the back of the fuselage, the heat also focused on the outlet, most of the heat accumulation in the cooling vents near the location, the surface temperature of 47.2 degrees celsius.

The 360 security guards on test, the result is 8.82 seconds, beat 99% of the country's computer. Although defeated 99% of the country's computer exaggerated, but the mixed hard disk B5400 Touch upgrade is very practical, for the user's daily reading experience is very obvious.

Through the above screenshot can be found, the notebook transcoding i5 processor with 45 minutes and 18 seconds, and equipped with a i7 processor B5400 Touch in just 39 minutes and 47 seconds for the video, the gap is very obvious. In the daily operation of the user multiple files, the whole experience of fluency, i7 4510U processor will bring obvious efficiency.

Although the E4430 is not suitable for playing games, but after all, equipped with 2G alone, and with good performance of i7 4510 processor, the low quality of mild amusement or no problem. At present, college students are more rapid games leisure time play "hero alliance" this kind of card requires lower, only four thousand head E4430 it is very cost-effective.

Hardware configuration at present have been upgraded to Haswell low voltage processor, a total of core i5 and I3 two versions, and equipped with a Radeon HD 8670M graphics card, this machine adopts hybrid drive, and increased APS hard disk protection function for the mechanical hard disk.

Considering that B4440s mainly for young students, at present many university dormitories are not equipped with air conditioning equipment. So we are in a no open air conditioning room, dormitory for 30 minutes to simulate running.

Performance test of Master Lu, is always like primary computer enthusiasts, but LENOVO B4450s also got 57899 scores. Since it is World Cup year, so the author by everyone for having heard it many times the "football 2014", "14" and "FIFA FIFAonline3" to experience LENOVO B4450s game performance.

In the hardware configuration, the Intel core i5 4200U processor the get the LENOVO M4400s equipped with 22nm process, the configuration of the 500GB hard disk, and a single 4GB DDR3 1600MHz high speed memory, graphics cards, the model uses a processor comes with the Intel HD 4400 core graphics and NVIDIA GeForce GT 840M graphics card.

NVIDIA GeForce GT 840M 28nm Maxwell GM108 chip based on GT, is the successor to the 740M. With 384 stream processors and 8 ROP unit, the 1029MHz core frequency, support dynamic acceleration to 1124MHz frequency, memory interface 64bit and 2GB DDR3 vram.
