In addition to say is, HP EliteBook 845 incorporates a backlit keyboard and keycap, higher brightness, because of some high, light will be from the gap through to.
HP EliteBook 845 Accupoint equipped with a pointing stick, friction trackpoint is much larger than the ThinkPad, increase the friction also helps to improve the pointing rod precision, with keys around, can be used as a temporary alternative a mouse.
HP EliteBook 845 with 50wh HP CM03XL Battery is currently the top business super, interface to retain the most abundant, before travel, received the highest rate is Z830, has the advantages of light weight, but also rich interface, for office people, this is very important, the left side of the 845 did not arrange the air outlet, as can be seen from the top to the bottom followed by the power jack, VGA interface, HDMI interface, 1 USB3.0 interfaces and a Headset microphone jack.
On the right side of the fuselage 2 USB3.0 interfaces and 1 RJ-45 Ethernet interface, in the front also has a SD card reader, in general, three USB3.0 interface fully meet our external equipment work requirements, while the standard size of the VGA and the Ethernet interface is the thickness of note this is difficult to achieve the.
Next we adopt the evaluation on the performance of CINEBENCH R10 software, finally the processor single core to obtain 6307 points, much nucleus to obtain 11270 points, good performance.
In order to facilitate testing of its performance, we choose AS SSD Benchmark this specifically for the SSD test software designed. You can test out continue reading of solid state disk write performance, including small 4KB file transmission performance and so on, show the performance can be divided into two kinds, one kind is the MB/s form, the other is a IOPS form.
In the AS SSD test, equipped with HP 256GB SSD solid state hard disk read and write speed reached 518.08 MB/ is read and write 460.16 seconds MB/ seconds, and the 4K random read speed reached 21.21 MB/ seconds, overall performance is quite well, compared with the traditional mechanical hard disk lifting is very obvious, especially 4K random read speed for program loading, system operation, such as high speed.
Thermal performance test is actually the biggest test of the notebook, itself inside the body space has been very small, coupled with the heat radiating large original, patency test a laptop inside Kung fu. Using metal fuselage and the fan is in how the HP 845 with HP EliteBook 845 G2 Battery cooling performance at a rotating shaft? By convention we use FurMark software plus AIDA64 system stability test to this machine in high load operating condition.
Surface temperature, we adopts the temperature detecting equipment of the professional notebook cooling performance testing. For the convenience of our observing the machine temperature distribution, we get the temperature distribution through the detection apparatus, recording and various parts of the marked temperature, illustrated as follows:
From the point of view of temperature distribution, most of the machine heat accumulation in the cooling air outlet position, the highest temperature is only 49.6 degrees, the palm rest area less heat, palm temperature performance support outstanding in the practical experience in the long time.
The power supply is adjusted to the HP HSTNN-IB4R Battery saving mode, after a period of time after the test, finally got 13 hours and 26 minutes test scores, such endurance performance in many super this performance is very amazing, almost single cell ultra endurance performance in the longest product.
Endurance test software aspect, we choose is PowerMark, which is the same as PCMark, 3DMark, is developed by FutureMark company. It will continue to cycle running a set of test scripts, including four kinds of common application: Internet browsing, document processing, video playback, 3D game, so as far as possible to the actual use of the close of the vast majority of users.
Mirror design HP 855 with HP EliteBook 855 G2 Battery screen use, although not by fog screen surface anti reflection effect, but in the picture on the permeability has absolute advantage.
HP's EliteBook series are positioning high-end business notebook, designed for America military standard MIL-STD-810, performance in terms of security is very good, extreme environment has very high reliability and outstanding performance, including harsh temperature, altitude, humidity, dust, shock and vibration conditions.
The thickness, the thickness of the 18.56mm is not a particularly good results, but is not important, after all, similar products such as XPS13 thickness in 18mm or so, and this design to some extent to both interface of volume, and weight, 1.19kg score very out of color, fully meet the requirements of portability.
Today, we get the HP EliteBook 845 G2 with built-in HP EliteBook 845 Battery, compared to the previous generation products, thickness decreased by 40%, reduce the weight of the 27%, also brought a lot of important enterprise characteristic, enable the company to provide extremely the TM experience for all employees. This series of products mainly for the user design often travel, paired with an optional battery, battery life up to 33 hours, and the product has passed the most stringent MIL-STD 810G USA military standard test, to ensure that the products of high reliability.
How to distinguish good and bad heat dissipation performance, the highest temperature can not represent what. Ventilation vent temperature is the highest, if not, it is only that the heat dissipation problem. When most of the heat accumulation in the cooling vents near the location, and other parts of the temperature not higher than 36 DEG C, it can determine the cooling system design belongs to a more reasonable.
The appearance, HP 740 keyboard and HP EliteBook 740 G2 Battery face contracted design style, using the same alloy material to create, color also is metal silver, but with the top cover is not the same. Keys and touch panel and C surface to maintain a unified style and color, the overall performance is very strong.
As a notebook, appearance design, heavy thickness are just the surface of Kung Fu, priority among priorities it is inevitably the performance configuration. Xiaobian believe that every time at this link you will look forward to, because in front of the screen, the keyboard, the interface appearance, introduced are only foreshadowing, the real climax in the performance evaluation of the final link. This small make up respectively by PC Mark, 3D Mark 11, CPU Z, GPU Z, Street Fighter 4, a total of five kinds of software of HP 855 G2 configuration and performance is presented.
HP 855 G2 with 6cell HP EliteBook 855 Battery in 3D Mark 11 score was 1363 points, the scores can be said is not very high, but for daily watch HD movies, video conference will have a greater impact.
