| Dell Latitude E7240 |
The dell Latitude E7240 may be a mobile 12-inch ultrabook, that ought to balance the benefits of a slim style and therefore the high demands of skilled business customers. However, dell presently solely offers a restricted range of choices in its on-line search. with the exception of additional CPU choices, a touch-capable full HD show, more RAM, integrated WWAN or a lot of storage capability ought to be optionally out there within the future. Our take a look at device options associate Intel Core i5-4200U-CPU with integrated Intel HD Graphics 4400, 4 GB RAM, a 128 GB SSD and a matte HD show. In Dell's on-line search, cyberspace worth was concerning 930 Euros (approximately 1110 Euros as well as VAT/~$1256 and $1499 respectively) when deduction of all discounts at the start of the take a look at. in the meantime the bottom worth of a rather totally different model hyperbolic to 1069 Euros (~$1444) while not VAT.
Case
Two-color case with good look.
Two-color case with good look.
The take a look at sample options a dual-color Al case. The side is anodized and therefore the keyboard aspect options a victim surface. we tend to just like the good look. Latitudes have sometimes return while not chrome strips or shiny components anyway. The silver lid slightly warps from region twisting, however seems to be stable and simple to scrub. Moderate pressure doesn't have an effect on the image once the screen is on. the soundness of the bottom unit isn't good either. It visibly bends from region twisting. though this doesn't impair everyday use, the flexural rigidity cannot continue with the ThinkPad S440's and slightly reduces the premium quality impression.
Dell advertises that this laptop computer meets the MIL-STD-810G customary in a very video concerning the Latitude 7000 series, however it doesn't specify what parts of the quality it fulfills. MIL-STD-810G consists of tests with extreme temperatures, atmospheric pressure, sunlight, moisture, chemicals, accelerations, and vibrations.
The build quality of the dell Latitude E7240 is extremely good; the palm rests show no depressions once ironed with a finger, the show hinge holds the screen safely in situ and therefore the style of the case seems to be solid.
Although the burden isn't particularly low, it's still terribly moveable at 1340 g (~3 pounds). The replaceable battery and therefore the standard tying up port square measure benefits.

Connectivity
The property is sweet for associate ultrabook. with the exception of USB three.0 ports (1x with charging function), that became customary within the in the meantime, the dell Latitude E7240 options a regular HDMI interface and a mini DisplayPort for digital affiliation of external shows. additionally, it's a card reader and a standard Gigabit computer network interface. In our opinion, the interface layout is sweet. There square measure spare interfaces for connecting the standard peripherals like printer, external display, onerous drives or optical drive on the rear aspect while not worrisome cables left or right of the notebook. the proper aspect homes another USB port, which may be accustomed quickly connect a camera or a smartphone.
Communication
WLAN performance as compared
WLAN performance as compared
Our take a look at model comes with a dell Wireless 1506 Wi-Fi module and 2 antennas. It uses the two.4 rate band and will deliver the goods transfer rates of up to three hundred Mbit/s, in theory. Signal strength and property to our 802.11n router with Ralink RT2860T chip were traditional. we tend to unbroken the laptop computer in line of sight of the router and measured the Wi-Fi performance in a pair of, five and ten meters (~6.6, 16.4 and 32.8 feet respectively) distance. The results square measure between four.3 MB/s and five.77 MB/s.
Our take a look at model doesn't have a intrinsical Bluetooth module. Apparently, the dell Latitude E7240 solely supports Bluetooth, if it's already integrated within the local area network module. for instance, Dell's Wireless 1601 will, however it's not nevertheless out there. identical is true for the WWAN modules (HSPA+ or LTE) mentioned within the specs.
An HD net cam, a twin array electro-acoustic transducer (both within the show bezel) and a regular Gigabit LAN port complete the communication system. Despite that specialize in premium quality, the net cam's image quality {is solely|is merely|is simply|is just|is barely} modest and would possibly only fulfill basic necessities of video conferences. colours hardly look natural, there's visible noise and brightness variations worsen the impression.
Security
The security options of our take a look at device accommodates solely the standard BIOS and system passwords. A fingerprint reader, Dell's knowledge protection security answer (with many security and encoding tools) and a smartcard reader square measure optionally out there for a surcharge. additionally, you'll change the sure Platform module and therefore the Computrace service within the BIOS (F12).
Maintenance
All-important elements square measure below rock bottom plate. it's straightforward to urge to the fan and clean it. A second RAM slot continues to be free and may be used for quickly upgrading RAM. The WWAN slot of our take a look at model is unoccupied too. However, attributable to missing antennas, a later integration isn't that straightforward. though the dell Latitude E7240 is associate ultrabook, you'll take away and replace the battery as you'd from any traditional business notebook.
Warranty
The warrant amount of Dell's Latitude 7000 series is thirty six months by default. The warrant includes basic service on ensuing workday. As usual, you'll add additional services and enhance the warrant amount. Dell e.g. offers a guaranty extension to five years professional support with on-site service on ensuing workday for an extra one hundred seventy Euros (without VAT/~$230).

Input Devices
Keyboard
The standard keyboard options full-sized keys in a very 19mm grid and includes a backlight feature. The latter has four brightness levels and improves the already sensible legibility of the key labels in low light-weight conditions. The FN combos have a unique color (bright blue) and may be simply distinguished from the quality functions.
While the keyboard is slightly lively around "J", it's rather stiff generally. due to the medium key travel, the quiet sound and therefore the good point, prolific writers can just like the keyboard and you'll solely would like a brief time to urge accustomed it.
Touchpad
The touchpad options slightly sensitive surface of ninety x fifty millimetre (~3.5 x 2.0 inches) and convinces with sensible flying traits. customary commands work well, however the scale is usually too little for multi-touch gestures. we tend to just like the separate buttons with their rubberized surface. they're responsive and quiet. Our take a look at model doesn't feature a TrackPoint.
HD show with matte surface
HD show with matte surface
Our dell Latitude E7240 comes with a matte twelve.5-inch HD show with a resolution of 1366 x 768 pixels. this offers a component density of one hundred twenty five dpi. The compromise of screen property and image size is sweet and can be liked by several users. dell needs to supply a full HD show with bit support presently. However, alike several alternative choices, it couldn't nevertheless be organized at the time of testing.
The show brightness has ten levels, starting from a minimum of eight cd/m² (center) to a most of 237 cd/m² (upper middle section). Level seven corresponds to a brightness of 146 cd/m² then we tend to used it in our Wi-Fi take a look at. This brightness is usually spare and comfy for the eyes inside. the typical most brightness is 210 cd/m² and therefore the brightness distribution of eighty one is satisfactory. The brightness isn't reduced on battery. Combined with a matte surface, you'll work rather well outdoors. However, the dell Latitude E7240 permits solely restricted use on significantly bright summer days or in direct daylight.
The distinction of 334:1 is simply too low for multimedia system applications. Black appearance gray and colours look pale. the colour area is concerning hr of sRGB and not appropriate for skilled image written material. identical is true for grey levels, color exactness, and color saturation with plant settings. you'll clearly see the variations with naked eyes because the average DeltaE 2000 values square measure concerning nine. though activity can visibly improve the values, the tiny color area and therefore the important deviations in blue and magenta clearly show the restrictions of the show.
The viewing angles of the HD show square measure typical for Tennessee technology. within the vertical direction, colours invert or the image gets brighter with increasing angles. additionally, you'll see slight color changes. within the horizontal direction, the viewing angles square measure abundant wider. Therefore, the show is clear for many persons. Brightness decreases and colours amendment solely slightly here.

Performance
Three pre-configured models of the dell Latitude E7240 were offered at the time of testing. Despite discounts, none of the 3 may be a discount compared to Dell's usual costs. the highest model options Intel's Core i7-4600U-CPU, a 256 GB SSD and eight GB RAM. the value is beginning at 1470 Euros (~$1985) while not VAT while not extras. though the bottom worth of 1070 Euros (~$1445) while not VAT of our base model is considerably lower, the value continues to be steep and therefore the hardware was considerably axed. rather than associate Intel Core i7-CPU, it options Intel's Core i5-4200U-CPU. With 4 GB, solely 0.5 the RAM capability is accessible, and therefore the SSD features a little gross storage capability of solely 128 GB for today's standards.
System information: dell Latitude E7240
Processor
Similar to most new Haswell laptops, Dell's Latitude E7240 additionally uses associate ultra-low-voltage CPU. the facility demands of chipset, memory controller, and Intel's integrated Graphics 4400 square measure already enclosed within the low thermal style power of fifteen Watts. So, the whole power consumption is low, that is vital for sensible battery life. The performance of the Intel Core i5-4200U processors is concerning on par with the Intel Core i3-3110M-CPU's with a TDP of thirty five Watts. The take a look at model achieves 4948 points (single rendering) and 9943 points (multi rendering) in Cinebench R10 64-bit. wPrime calculates 1024m (multithread) in 672 seconds and SuperPi 32m (single thread) ends when 748 seconds.
In a realistic take a look at, we tend to regenerate video and audio files. If the conversion tool will use Intel's fast set Video, conversions will typically - counting on the supply and therefore the destination format - be done quickly. If a conversion task solely runs on the CPU, it would take considerably longer due to a high system load. In distinction, audio conversions with iTunes take advantage of high CPU clocks. The Intel Core i5-4200U-CPU reached thirty eight.9-fold speed. Its rank among Haswell ULV CPUs conforms to its clock rate.
The performance doesn't fall on battery power. The CPU clocks with its base clock of one.6 rate and therefore the GPU clocks between 950 to one thousand megacycle per second below continuous full load, however the clock rate didn't fall below these. we tend to ran the take a look at with Dell's energy profile "Ultra Performance (Max Fan Levels)".

System Performance
The system performance of the dell Latitude E7240 below review is, overall, balanced. The RAM capability of 4GB can be improved. A second module won't solely increase the RAM capability however additionally activate twin channel mode. The latter won't solely improve memory performance, however additionally increase the performance of the shared memory graphics by concerning ten - twenty fifth. The take a look at model achieves 4529 points in laptop Mark seven and 2423 points in laptop Mark eight (Work).

Storage Devices
The dell Latitude E7250 is simply too slim to deal with a a pair of.5-inch drive. Therefore, it used associate mSATA-SSD from Lite-On IT with a gross capability of 128 GB instead. However, the out there capability {is solely|is merely|is simply|is just|is barely} spare for basic necessities and may only be extended by commutation the mSATA module. however, the performance is convincing with 493 MB/s in serial reading and 303 MB/s in serial writing. The low interval of zero.1 ms is typical for associate SSD and improves the quick user expertise, although HD Tune isn't the most effective benchmark for non-mechanical drives.

Graphics card
The Intel HD Graphics 4400 integrated within the processor is quick enough for several forms of tasks and may be a sensible answer in a very business ultrabook. Full HD videos run while not inarticulate , Intel fast set Video will accelerate video conversion and therefore the performance is spare for unexacting games. many options as well as support of Intel's Wireless show and up to a few displays at the same time square measure appreciated within the business vary. Still, the sparing graphics unit isn't powerful enough for hard 3D tasks. Dedicated graphics cards square measure far better here and deliver the goods considerably higher frame rates.
The E7240 solely achieves 3167 points in 3D Mark Vantage and 725 points in 3D Mark eleven. Adding a second RAM module would activate twin channel mode and therefore the shared memory graphics card would take advantage of the improved memory performance. As a result, the graphics performance would increase by ten - twenty fifth.
The graphics performance falls neither below full load nor on battery. The GPU will reach its most clock rate of one thousand megacycle per second here.
