The connectivity is good for an ultrabook. Apart from USB 3.0 ports (1x with charging function), which became standard in the meanwhile, the Dell Latitude E7240 features a standard HDMI interface and a mini DisplayPort for digital connection of external displays. In addition, it has a card reader and a conventional Gigabit LAN interface. In our opinion, the interface layout is good. There are sufficient interfaces for connecting the usual peripherals like printer, external display, hard drives or optical drive on the rear side without disturbing cables left or right of the notebook. The right side houses another USB port, which can be used to quickly connect a digital camera or a smartphone. In addition, a card reader is placed there, making it easily accessible.

Three pre-configured models of the Dell Latitude E7240 were offered at the time of testing. Despite discounts, none of the three is a bargain compared to Dell”s usual prices. The top model features Intel”s Core i7-4600U-CPU, a 256 GB SSD and 8 GB RAM. The price is starting at 1470 Euros (~$1985) without VAT without extras. Although the base price of 1070 Euros (~$1445) without VAT of our base model is significantly lower, the price is still steep and the hardware was significantly axed. Instead of an Intel Core i7-CPU, it features Intel”s Core i5-4200U-CPU. With 4 GB, only half the RAM capacity is available, and the SSD has a small gross storage capacity of only 128 GB for today”s standards.
The system performance of the Dell Latitude E7240 under review is, overall, balanced. The RAM capacity of 4GB could be improved. A second module will not only increase the RAM capacity but also activate dual channel mode. The latter will not only improve memory performance, but also increase the performance of the shared memory graphics by about 10 - 25%. The test model achieves 4529 points in PC Mark 7 and 2423 points in PC Mark 8 (Work).

The Dell Latitude E7250 is too slim to house a 2.5-inch drive. Therefore, it used an mSATA-SSD from Lite-On IT with a gross capacity of 128 GB instead. However, the available capacity is only sufficient for basic requirements and can only be extended by replacing the mSATA module. Nevertheless, the performance is convincing with 493 MB/s in sequential reading and 303 MB/s in sequential writing. The low access time of 0.1 ms is typical for an SSD and improves the fast user experience, though HD Tune is not the best benchmark for non-mechanical drives.
The Intel HD Graphics 4400 integrated in the processor is fast enough for many kinds of tasks and is a good solution in a business ultrabook. Full HD videos run without stuttering, Intel Quick Sync Video can accelerate video conversion and the performance is sufficient for undemanding games. Several features including support of Intel”s Wireless display and up to three displays simultaneously are appreciated in the business range. Still, the frugal graphics unit is not powerful enough for demanding 3D tasks. Dedicated graphics cards are much better here and achieve significantly higher frame rates.
The E7240 only achieves 3167 points in 3D Mark Vantage and 725 points in 3D Mark 11. Adding a second RAM module would activate dual channel mode and the shared memory graphics card would profit from the improved memory performance. As a result, the graphics performance would increase by 10 - 25%.
The graphics performance falls neither under full load nor on battery. The GPU can reach its maximum clock rate of 1000 MHz here.

Casual games like Angry Birds or Fruit Ninja do not pose a problem for the Dell Latitude E7240. Even undemanding titles including World of Warcraft can be played very well with medium settings. Higher resolutions or slightly higher details are possible in this game. You should definitely deactivate anti aliasing in Diablo III so it will run smoothly and the performance will increase. Like many Dell models, the Latitude E7240 does not support several usual resolutions including 1366x768 and 1600x900 pixels on external monitors leaving our tests limited to the available resolutions.

The Dell Latitude E7240 only gets louder when the performance requires it. In low load scenarios, it works quietly or with very low fan activity most of the time. When the fan runs for a short time between the silent times, we measure a quiet 29.3 dB(A). The noise of 37.4 dB(A) is clearly audible under medium load. Under full load the noise increases to a maximum of 40.3 dB(A) to 43.3 dB(A). We did not observe a high frequency or pulsating noise.

Although the Dell Latitude E7240 is hardly audible under low load, the case remains cool with a maximum of 31.2 °C (88.16 °F). But, this changes under permanent full load for at least one hour. The rotating fan causes a noise of 43.3 dB(A) and can no longer keep all parts of the case cool. We measured temperatures from 45.1 °C to 49.6 °C (113.18 to 121.28 °F) in four segments on the underside. The temperature even increases to 55.7 °C (132.26 °F) at the vent grille. You should not use the laptop on your lap in this load scenario. However, you can use it on your desk without problems, as the temperatures stay uncritical in the keyboard and touchpad area.
The sound is dominated by trebles, but you can hear more basses and mid tones than usual in a business notebook. Although the sound is not sufficient for a great multimedia experience, Internet videos, radio broadcasts and background music profit from it. You can change the volume from zero to 100 by two steps. The maximum volume is good and virtually distortion-free. But, external speakers are necessary for presentations to a larger audience. You can connect such via 3.5 mm jack (combined audio in/ out), HDMI, or USB.
The power consumption of the Dell Latitude E7240 is very low. We measured 3.7 Watts while idle and up to 34.8 Watts under full load on mains. Both results indicate the possible range of power consumption and are not realistic. Under full load the power consumption falls by about 3-4 Watts after a short time, as the CPU clock decreases to 1.6 GHz to 1.8 GHz. In idle mode with minimum display brightness, it is hardly possible to use the Latitude E7240, as you will hardly recognize the display content with a display brightness of 8 cd/m². The power consumption is about 6.5 Watts with settings suitable for office use. The relatively low power consumption is necessary, as the battery capacity of 31 Wh is rather low. Dell offers a 41 Wh model as an alternative, but neither price nor availability was known at the time of testing.

We could not run the usual Battery Eater tests on our test model due to an incompatibility problem, which we could not solve. Therefore, we manually measured the time with the same settings. During reading with low load and maximum energy settings, minimum display brightness and disabled Wi-Fi, the Dell Latitude E7240 achieved a battery life of 7:42 hours. In our Wi-Fi test with brightness level 7, the battery life decreases to 4:33 hours. Under full load (maximum display brightness, profile maximum performance, Wi-Fi on, Battery Eater Classic without recording), the device ran for 1:16 hours. The battery test of PC Mark 8 (Work) recorded a battery life of 3:33 hours. The optional 41 Wh battery should increase the battery life by about one third.
