DELL Inspiron 3451 3458 3551 3558 review

DELL Inspiron's 3451 top cover is not much special, the transition of the arc is more natural, and the former M40 demarcation line is clearly different, 3451's top cover is a complete single panel. For business users often carry out characteristics, Inspiron 3451 material aspects of the after special treatment, a very good solution to the feel and durability, the surface is not easy to leave fingerprints, also moderate friction can also effectively prevent the accidental fall.

C face using a molding board, the stability has been a very good guarantee. Inspiron 3451 with DELL patented technology of high touch keyboard, keyboard keycap radian after testing, especially suitable for pressing the fingers, the best elastic keyboard and key spacing design for smooth and fast input laid the foundation.

DELL Inspiron 3451 with 40wh DELL Inspiron 14-3451 Battery is a commercial laptop for SMEs, in the hardware and software, the application of a variety of enterprise level application scenarios have done enough preparation and optimization.

In the aspect of hardware, the Inspiron 3451 equipped with TCM hardware encryption technology, is different from the traditional software encryption, TCM in both in the security of the encryption and encryption speed brought qualitative improvement, the use of TCM encrypted data, forced to decipher the theory need 10 years of time. At the same time, Inspiron 3451 integrated APS protection chip using built-in acceleration meter to determine the motion state of the notebook, accident head will be automatically from a high-speed rotating disk to recover, try their best to protect the security of user data, from carry notebook shuttle in the office without fear.

In the software, the collection of the DELL intelligence collection center of a variety of functions, very intuitive and practical. DELL 3451 with 14.8V 4cells DELL Inspiron 3451 Battery integrated intelligent fingerprint identification, system key optimization, a key recovery, USB management, and other practical software.

DELL in fingerprint identification based on the development LenovoSmart FingerPrintInspiron intelligent fingerprint identification software, using this software, the user can choice will commonly used software and ten finger fingerprint binding, brush a fingerprint up to three different procedures to start.

We'll take a look at the machine interface on the left, from left to right followed by the distribution of the a power interface, a network interface, a cooling fan hole, an HDMI interface, a USB 3.0 port and a SD card slot. Although the distribution of the machine is not particularly unique, but it is worth mentioning that the machine's heat sink. After reading the front of the machine at the bottom of the introduction, I believe we will find that DELL Inspiron 3458 than the general notebook has more heat dissipation. In small series seems to have a good heat dissipation for a laptop can also play a very important factor in success. At least a small series from this point can be seen DELL Inspiron 3458 WITH 4CELL DELL Inspiron 14-3458 Battery good thermal performance.

Finished appearance, screen, keyboard and interface to the very serious roast machine part, after all, the kind of just look at appearance does not care about performance, more don't care about the price really tyrant or minorities. This small series uses a total of eight kinds of techniques, more three-dimensional way to give you a thorough introduction to the new DELL Inspiron 3458 performance exactly how.

We can see that the full page silver appearance in the yen value on many points. Although the cover is a composite plastic material, but imitation silver metal coating texture is not worse than that of metal. Touch feel is really good, there is a feeling of love their goddess.

Corner also sleek design although not to appear for the first time in Eurocom products, but in this shark 4 into, let me she wasn't a rough man to pull the foot feeling, more like a sleek sister paper.

First of all, we have a look at the new DELL Inspiron 3458 on the Mark PC performance, the machine runs out of 2673 points in the conventional Work model. This result is still very good in its same price products, familiar with the computer's friends will know Mark PC as a comprehensive evaluation software for the whole performance. So the single from this score on the new Inspiron 3458 is a relatively good choice, for the daily entertainment and leisure, business, it can be easily competent.

The new DELL Inspiron 3458 with 4cells DELL Inspiron 3458 Battery in the Mark11 3D performance is 1797 points, the score of the P represents the normal test level is medium grade. Or the phrase goes, the Inspiron 3458 same price field the score is medium level, needs to be emphasized is the test Xiaobian is opened in the highest performance, so it can fully exhibit the highest display level.

We use Aida 64 and Furmark software on the CPU / GPU double baking machine test. After about 20 minutes of time can be seen, the machine core temperature is roughly at around 96 DEG C, the core temperature average 92.8 DEG C, for a piggyback the i7 4710mq products speaking, the bulk thermal properties belong to the mainstream standards.

In addition to the game book, the user is also very concerned about their cooling capacity, we have a cooling test on the 3551 with DELL Inspiron 15-3551 Battery, to see the specific situation:

And the actual cooling experience point of view, this machine is the main heating elements are arranged on the left side of the keyboard, feeling, left to feel a certain quantity of heat, right hand of cool and refreshing feeling, the overall feel comfortable.

First we take a look at the mainstream stand-alone game testing. The test game we choose is "biochemical crisis 6". This is because the current biochemical crisis 6 on the hardware requirements of the vast majority of mainstream games on the hardware requirements, here we take a look at the test case:

The first test is the default, 1080p Full HD resolution in the actual results are not satisfactory, after all, equipped with DELL Inspiron 3551 with 4cells 40wh DELL Inspiron 3551 Battery only a piece of GDDR3 discrete graphics, full HD resolution for graphics performance loss is relatively large of, so we will distinguish rate adjustment to 1600 x 900 of the test, other effects was the highest.

We use Furmark pager software for Dell Inspiron 3558 limit test, Furmark will full machine two large heating components of CPU and graphics operation and run 60 minutes after the temperature up to a limit of the height, in order to let everyone can be more intuitive see each machine in operation when the heat, we also use the fluke infrared thermal imager, respectively to observe the location of each temperature heating.

Through the limit Kaoji test, we can see 3558 with DELL Inspiron 15-3558 Battery fever. From the point of view of the keyboard area, the highest temperature in the position of the guide bar to 48.8 degrees, affected by the keyboard area of central temperature is maintained at 40 DEG C, relatively keyboard on both sides of the District, a touch panel and palm rest part of the temperature control performance is pretty good.

Dell Inspiron 3558 fuselage high-temperature zone is concentrated in the vicinity of the heat radiating window, the highest temperature close to 50 DEG C, at the bottom of the hollow part of carrying the heat dissipation function, internal temperature of 44.3 degrees Celsius, the vast bulk temperature control at about 35 degrees. Dell Inspiron 3558 equipped with a piece of AMD radeon R7 M260X independent graphics. The main source of it is also a heat, in daily office, basic does not appear full load, so as long as it is not in the extreme natural conditions, Dell Inspiron 3558 with DELL Inspiron 3558 Battery temperature control performance or trustworthy of.
