So, you do not have the pleasure of connecting external hard drives, a laptop computer through the door quickly in the future. At least Dell has installed the eSATA port. However, access speed, the new USB 3.0 interface. Alternatively, you can use a FireWire port for this.

It can easily happen that the big cap covers a nearby port due to the arrangement of the interface. Dell, namely the ports located close to each other. It may well be that a big stick USB covers the other USB port and even HDMI connector on the left. ExpressCard slot Dell Latitude E5520 has is appreciated. Thus, the laptop has an option to extend simple.

Our test sample of Dell Latitude E5520 comes with a good "clean" system Windows 7. Less than 40 programs have been installed on the hard disk. However, Dell also stops the programs included. Must be purchased with the order.

In addition to the actual laptop, including the AC power cable and the printed documentation is fortunately also a recovery DVD with food. Most manufacturers do not include such a DVD and prefer to create a recovery partition on your hard drive. But the customer loses the memory of the hard drive.

Dell Latitude E5520 with a full warranty. Instead of one or two year warranty, the Latitude E5520 is equipped with a full warranty period of 3 years. This warranty includes onsite service next business day. There are also many other services that the customer can be ordered as an accessory.

List of other services is long and varied Certified Data Destruction to the theft and accidental damage. Opportunity to go back to the laptop, and are equally available to extend the battery life of service. More bundles of validity can often extend to 3 years.

Dell uses a 15.6-inch LED screen with a resolution of 1366x768 pixels. Fortunately, Dell installs a matte screen in the Latitude E5520. Therefore, no theoretical basis in the way of working out. Dell Latitude E5520 Another is alternatively available with a matte screen Full HD with Dell's online store (1920x1080 pixels). Supplement between our sample and the model with HD display is only 50 euros and includes a hard disk of 500 GB instead of 320 GB hard drive.

Latitude E5520 screen has a base of good brightness. The brightness of the screen is at an acceptable level with an average brightness of 219 cd/m2. Even the lighting of the screen is nice. It's close to perfection with 94%. The value of contrast black and are much less recoverable.

Although the value is high in black 1.36 cd/m2, contrast suffers and is only 136:1. This is not particularly impressive and there is a clear need for improvement. In addition, we found that the brightness is automatically reduced in battery mode during our tests. When the computer is connected to a power, the center has a brightness of 222 cd/m2.

The rate drops to 181 cd/m2 in battery mode. This results in a loss of brightness by nearly 20 percent. The Dell Latitude E5520 screen can not score in the reproduction of color, but not in a mobile office anyway. Although you can still determine sRGB large enough coverage, the Adobe RGB color spectrum is far from being reproduced in its entirety.

Dell Latitude E5520 prices outside. No display can show all his strengths here. The difference between the reflective screen is very clear in direct comparison. The readability is excellent in the shade. The readability is slightly weakened in direct sunlight. However, the contents of the display is clearly legible.

Dell Latitude E5520 Laptop heart is an Intel Core processor i5-2520m. This is a high-end dual-core processor, the current family of Sandy Bridge. The processor has a very low power at 2.5 GHz by default. The processor will also be able to overclock at different levels of performance should be tight.

Single core can be overclocked up to 3.2GHz, if necessary. Clock speed can be increased to 3.0 GHz, both cores would be needed. The processor is also suitable for complex tasks, such as HD video editing or 3D games, because of its capacity. The CPU has nothing more strenuous than the smaller models, a TDP of 35 watts.

However, the Intel Core i5-2520m enjoy more than 35 watts, for example, an Intel Core i5-2410M. The processor is also suitable for laptops with a screen 14 inches or more, because the TDP of 35 watts.

Intel HD 3000 graphics card supports the contents screen show. It is integrated directly into the processor, and therefore do not need additional cooling. Although not one of the most powerful graphics cards on the market, it may well compete with entry-level card that Nvidia GeForce 310 million.

A major advantage of the Intel graphics HD 3000 is also before the low power consumption and performance. However, it is possible to play older games smoothly on the graphics card. A couple of new games can also be done smoothly, but a net loss of resolution and quality must be accepted.

Unfortunately, we must use 32-bit versions of our benchmark programs, as only a 32-bit version of Windows 7 was installed on our Dell Latitude E5520, but the laptop normally offered by the 64-bit version of Windows 7 in online shops as well as directly on the Dell.

We use Cinebench R10 32-bit processors to determine effectiveness. Latitude E5520 reached a score of 4059.0 points in Cinebench R10 rendering single (32 bits) and is well above our table. It also rates well compared to other notebooks with an Intel Core processor i5-2520m.

The distance from the top model, Schenker XMG A501 (2520m GT 540), with 4111.0 points is not very big. Latitude E5520 is far enough ahead with 8820.0 points in Cinebench R10 rendering multi (32 bit) reference. Latitude E5520 again scores well in comparison with laptops that use the same processor. The top model with Core i5-2520m processor, the Toshiba Tecra R840-11F (2520m, HD 3000 Graphics) with the 8858th

0 points in the Cinebench R10 benchmark performed multiple. Therefore, taking the top model of the Dell Latitude E5520 is not particularly large. Although the Dell Latitude e6520 has a powerful processor (the i5-2540M), but venture a direct comparison of the two laptops. The Latitude E5520 is not a bad job. It is always slower than marginally.

The Dell Latitude E5520 reached 7029.0 points in the reference system, PCMark Vantage, and therefore in the upper third of the entire image. Laptops comparable with the same material as the Lenovo ThinkPad NYV4UGE L420 (2520m graphics HD 3000), are at 6601.0 points.

Laptops, Lenovo IdeaPad like Y560p-M61G3GE (2630QM, 6570M HD) with 6996.0 points, slightly below the latitude E5520 laptop. The Latitude E5520 may well be said more clearly in our PCMark benchmark 7. It is the best laptop nominal i5-2520m Intel Core and Intel HD 3000 graphics card with 2477.0 points. Overall, the Dell Latitude E5520 does a good job in the reference system.

This is also evident in direct comparison with the Dell Latitude e6520. The Dell Latitude E5520 laptop even has an advance on the laptop e6520 (E5520: e6520 vs 7029.0 points: 6629.0 points) in PCMark Vantage.

As expected, the Latitude E5520 can not excel with the Intel graphics HD 3000 graphics benchmarks. Included in the diagram offers no surprises in our graphics tests. Dell Latitude E5520 is almost the lower half of 4590.0 points on the map.

Other notebooks in the vicinity of the Latitude E5520, including the Sony Vaio Sony VAIO VPC-SB1Z9EB (2520m, 6470M HD) and 4615.0 points, or 13-inch Apple MacBook Air MC966D 2011-07 / (2557M graphics card HD 3000) with The 3808.0 points. Compared to the laptop Dell Latitude E6520, Latitude E5520 does not need to hide here, either. Although the Latitude E6520 is still leading 3DMark05 benchmarks, the Latitude E5520 E6520 that in 3DMark06 benchmarks.

A 2.5-inch hard drive from Western Digital is used in our Latitude E5520 test sample. The WD2500BEKT-75PVMT0 has a capacity (gross) 250 GB and a speed of 7200 rpm. It is very fast with an average transfer rate of 73.1 MB / s. Only the access rate of 17.6 milliseconds is slightly lower than the hard drives with a speed of 5400 rpm.
