Dell Latitude E6400

Freitag, 21. September 2012

During the summer, Dell Latitude E6400 renewed its professional range with the “E” series. There are many improvements over the previous generation including a completely new chassis advertised as particularly rigid and features – often optional – who are upgrading from the competition. The Latitude E can thus receive a screen with LED backlight brightness sensor, a backlit keyboard, HSDPA modem, etc.. At the technological level, the range is of course based on the platform “Centrino 2″ and Dell announced a range quite impressive despite the presence of an NVIDIA Quadro NVS 160m. There are so many things to check with our Dell Latitude D620 Battery premium …

New look

Black and angular, the new Latitude E etrennent what Dell calls the “Industrial Design”. Fans of the famous Thinkpad will not be disoriented! Even large silver hinges with beveled corners are clearly inspired by the design of Big Blue … The double scoring system is still present but the trackpoint inherits a third button, once again, just like the Thinkpad! With the range Dell Latitude D630 Battery, Dell attack so clearly its competitor always in the workplace.

From the first minutes of the grip, the Latitude E6400 mark a clear break with the previous generation (eg D620): Exit plastics painted and moderately stiff. The Dell Latitude E4200 Battery inspires quality and rigidity. In fact, it does not inspire: it’s solid! The opening screen is a central button that leaves an impression somewhat mixed. But the hinges are exemplary. They are firm and wish to hold the screen perfectly in place. No game to lament, not the slightest oscillation of the screen and they keep strictly slab regardless of angle (limited to 160 °).

New chassis!

For information, the first portable Dell Latitude E5400 consumer prices and use a simple plastic shell and ribs provide rigidity … The only metal parts are usually hinges. The Latitude older generation used a frame “device” called “tri-metal”. A name for a highly technical architecture actually quite commonplace now used by mobile phones mid-range … With the Latitude E line, Dell has inspired once more Lenovo to introduce a structure similar to the “Roll Cage” aboard the Thinkpad. The Dell Latitude E5420 motherboard and thus the hinges are grafted on a single piece of metal that provides rigidity copy. Unlike the “Roll Cage” Thinkpad (magnesium structure and outer shell internal plastic), the chassis of the new Latitudes E is “internal and external”. Clearly, some parts of the structure are also involved in the hull and the cell line (especially the back where the hinges attach). In the absence of truly innovate, Dell turn uses a technique very accomplished. Note that Dell and Lenovo are not yet in a totally one-piece chassis as the “Unibody” introduced by Apple with the latest Macbook and Macbook Pro (well ahead of the  Dell Latitude E5500 PC world) …

Under the laptop Dell Studio XPS 13, no question multiple access doors to the various components. A large metal plate “closes” the chassis. Must loosen 3 screws (2 for the hard disk and one for the cover itself) to access the internal components but the rigidity wins as the overall accessibility … You can also highlight the hard drive easily accessible: we do there are only three screws to unscrew to change disc (2 brackets and 1 for “caddy”)! In this idyllic picture, however, we note two caveats. The Dell Studio XPS 1647 hard drive is screwed directly to the chassis (no vibration system like the Thinkpad or Macbook Pro). Mechanical noise therefore tend to be magnified. Fortunately, this is only half evil insofar recent discs (same performance) are quite discreet. The second point “low” is metal against metal contact between the frame and the bottom cover. Despite a good fit and suitable tightening screws, frame issues sometimes “clong clong” fairly typical uninviting. Say they sabotage the perception of strength, they serve the intrinsic quality of the chassis … Simple “pad” easily eliminate these noises …

It turns?

For many of our readers, silent operation, especially in office is an important if not crucial in choosing a laptop. The Latitude E5500 we tested a model with a Core 2 Duo P9500 (2.53 GHz Penryn FSB 1066 MHz 6 MB cache) and a Quadro NVS 160m 256MB (580 MHz for the core and 16 stream processors at 1450 MHz), a configuration quite muscular for a 14 inch. Despite this power (albeit modest in 3D), the ventilation is triggered only rarely in office. As any fan PWM, starting a diet requires a little high but the speed drops very rapidly. The noise at cruising speed is weak and annoying (breath). Another important point, the fan stops almost immediately after a request from the processor and / or chipset. Only 3D games activate the fan at full power and it becomes audible. Last detail: Notebook heaters generally little … In the end, the Seagate Momentus 7200.3 250 GB is usually the largest source of noise. With an SSD, the Dell Latitude E5520 is a charm!

Pamper the user …

The Dell Latitude E6220 does not simply align the technological qualities. The backlit keyboard – Macbook copied – is one of the best we have encountered. Keys (smooth) are really nice to the touch, is exemplary firmness, running is good and it is quiet. Personally, I prefer even a “ICES” Thinkpad (note: NMB is the subcontractor that produces the “best keyboard IBM”). The Dell Inspiron 1520 lighting is controlled and may turn off automatically when the keyboard is not used or left on. Attention, the backlight option is charged € ~ 50 …

Without Trackpoint match the IBM scoring system “to stick” is correct. I must say that the addition of the third button is for many … However, the “cap” is quite small, rather poorly done, too soft and it does not provide as good a grip as the Thinkpad. In addition, it does not exceed enough buttons … Do not worry, it is quite feasible! The Dell Latitude E6320 touchpad recognizes movements of zoom and scroll “round and round” (like Samsung). Unfortunately, it does not autoscroll continuous or programmable zone and is not multitouch … Small detail, the palm rest is also metal … But unfortunately, like all metal parts of the Latitude E6400, it retains all traces fingers!

1440×900 screen with LED backlight is excellent. With the brightness set to 5 or 6, it competes with a TFT with a conventional neon. Maximum (level 15), the Dell Latitude E6420 screen is too bright for indoor use. Given the current weather conditions, it is difficult to estimate readability outdoors but without going too far, it should also be good. In the evening, a backlight set to 2, 3 or 4 is more than enough. A light sensor can dynamically adjust the backlight, which increases the autonomy … The angles are in the middle, without more, while color rendering is downright good and the backlight is uniform. Sump screen defends pretty well especially for a side stiffness model also end.

Multimedia, communication and connection

The Dell Latitude E6520 is equipped with a webcam, a microphone and a pair of speakers. If the first two do their job, the “speakers” are poor with his metal too. One would wonder if most Windows sounds were not changed until the record is different … Fortunately, the headphone jack does not suffer from this defect! The memory card reader is mounted on the front type SDHC but it did not recognize all SDHC test. Finally, the good old analog VGA port is supported by a digital DisplayPort.

Communication side, our Dell Latitude E6510 top model provides: Intel Wifi Link 5300 AGN Intel 82567 Gigabit V92 modem, Bluetooth and HSPA EDR (Broadcom). ESATA and FireWire complete the package. Infrared goes out the window … One ExpressCard slot and a docking connection can extend the capabilities of the machine.

Small details …

Dell Inspiron E1405 Battery has apparently treated its Latitude line E in detail. Thus, the power outlet is located at the rear as well as RJ11 and RJ45. The four USB ports are located on both sides of the laptop. Left or right handed, no cables will be penalized by adding an external mouse … Note that the lower left USB port is combined USB and eSATA! And yes, you might as well connect a USB device as a hard drive eSATA. Frankly practice! Usually placed in the wrist rests, the biometric reader is here next to the keyboard, as the speaker. This is more convenient when the laptop is used on the knees (provided they are handed) … In this type of application, we also appreciate the completely flat and smooth bottom of the laptop Dell Inspiron E1505.

The lights are blue including the webcam and the LED placed into the supply side laptop. The marriage of blue and black is a success story that gives the Latitude E a compromise between “restraint professional” and trendy design … Dell has not yielded to the latest fashion of placing areas tactile volume control or multimedia features. To assist the keyboard, the Dell Inspiron E1705 Battery relies on three buttons increase and decrease the volume and mute. Simple, clean, functional and unadorned: they love …

Mobility

The Dell Inspiron Mini 10 is a laptop 14 inches wide. It displays 2495 grams on the scale with high battery capacity of 85 Wh. As on Thinkpad T40p since it exceeds the back of the laptop. If the Latitude E6400 is one of the smaller models with 335 x 244 x 33 mm, do not forget to add 20 mm in depth for the battery “beyond” … The adapter is quite large (145 x 70 mm ) but very flat (16 mm), which facilitates the storage. And nothing to spoil, Dell Inspiron 13R is equipped with a two-pin plug (without unnecessary grounding). Side weight, it is a good average with 400 grams including cables. However, you will not have to wrestle you all day long because the autonomy of up to 6 hours with WiFi active and backlight controlled by the light sensor. With the backlight set to 50%, it is still 5 ½ hours under the same conditions … A perfect laptop for all mobile!

We can also note that the chipset Intel PM45 (Cantiga) enjoys a 65nm (although it is still ICH9m 130 nm) against 90 nm for PM965 machines Santa Rosa, which is beneficial for autonomy.

Dell Inspiron 1200 Last detail related to mobility, modular bay that contains a DVD burner Matshita here UJ862A is now 9.5 mm high (like the Thinkpad T Series) against 12.5 mm before. That would produce chassis as thin as competitors but in return, Dell no longer offers optional battery bay. It must pass through the battery slice that enhances the laptop quite significantly.

Performance

Dell Inspiron 1300 With a Core 2 Duo P9500, a Seagate Momentus 7200.3 and 4 GB of DDR2-800, this machine is swift frankly, whatever work to do. By cons, do not expect anything in 3D graphics chip as the Quadro NVS 160m. It is not more powerful than the Quadro NVS 140 that the Thinkpad R61 team tested last year … It does also not better than the FireGL V5000 and Radeon X1600 in T60 and T60p from 2006. Many opt for a model equipped with a GM45 PM45 instead of torque and Quadro NVS 140m. Without using the optional battery of 85 Wh, autonomy should be of the same ilk.

Dell Vostro 1520 here is not much to report about the performance but about the DVD compression. Indeed, the Latitude E6400 request almost a minute longer than the Thinkpad T61p with a less powerful processor. Curiously, the CPU load fell regularly for no logical reason.

Momentus, Digitus USB 2.0

We took advantage of the presence of the Dell Inspiron 14R eSATA port to test the Seagate Momentus 7200.3 250GB of origin in the internal bay and via eSATA and USB 2.0 via adapter Digitus and through a housing IcyBox. Connected via eSATA, the drive is as fast as in its internal bay (which is normal). Note that to take advantage of the “hot plug” eSATA, ICH must be configured in AHCI. Mode or IDE compatible, connect the disk causes system hang … Between USB and eSATA, the average transfer rate from 17 Mb / s to 72 MB / s. Sans comment! In these tests, we installed the system on a OCZ Core who is unfortunately clamped at ~ 110 MB / s read. In contrast, the Dell Inspiron 1464 Intel X25-m fully expressed!

Conclusion

With its range E Inspiron 1545 Battery, Dell introduced a new chassis that combines highly effective stiffness and accessibility. The change is also reflected in a change of look and the transition to the Industrial Design clearly developed to attract fans Thinkpad. The Latitude E6400 that we tested is equipped with the most powerful components for a 14 inch wide but it does not heat and fan noise never run more than necessary. High performance, the Toshiba pa3817u-1brs is also a reference in terms of autonomy: up to 6 hours battery with 85 Wh. To avoid spoiling anything, the keyboard and dual pointing are really perfect. They easily seduce any unconditional Thinkpad! Especially with the keyboard backlight option that matches the comfort of Thinklight. Still on the strengths, 1440×900 LED screen (optional) controlled by a light sensor is really a must. Default side, we can pin some noise associated with metal against metal chassis and enclosures poor. In the current offering, the Dell Inspiron 6400 is a laptop that we recommend …

Dell XPS M1530: 9.5 / 10

To: Rigid frame, design, finishes, hot little ventilation rarely active and quiet 6:00 85 Wh battery (optional) LED 1440×900 screen (optional), backlit keyboard (optional), 4 USB ports including a combined eSATA , DisplayPort, very good keyboard, trackpoint, 3 buttons, except leading performance …
