As far as wireless technology goes, the E5420 provides WLAN. The WLAN card uses the 802.11 b/g/n standards. Further to this the Broadcom NetXtreme 57xx Gigabit controller is also on board. Up-level your presentation: Present flawlessly with the optional FHD webcam and high-performing mics. performance is even worse. The Core i7-10610U has Intel’s ancient UHD graphics solution. It’s entirely inadequate for modern games or 3D applications. You shouldn’t expect to play any 3D game sold in the last five years, and even big budget titles from a decade ago can struggle at higher detail settings. Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light. Conclusions

Professionals and demanding users generally value the selection of ports very highly. The 14 inch notebook has everything on board that we would expect from a work notebook, without providing as many as a precision workstation would have. These include a screw tight VGA port, a PC-Card (PCMCIA) shaft, and FireWire. The older PC-Card standard, which has already gone out of fashion in the consumer world years ago (replaced by ExpressCard), is still popular in the business world. Using this special extension cards (mainly controllers) can be attached. The connection for fast external hard drives is also on board as eSATA, although there is no USB 3.0. Nothing about the Latitude 5420 suggests it might be a good laptop for anything unrelated to work, so perhaps it’s no surprise the display fails to hold up.To praise: Windows 7 Home Premium 32-bit is contained on a DVD. The user therefore doesn't have to create recovery discs, as is usually the case with other manufacturers.

Stay connected with up to 450 Mbps LTE mobile broadband speeds. Wi-Fi 6E allows 7 additional channels (in 6 GHz band) for more bandwidth, which provides faster, smoother Wi-Fi, especially in high-density areas. Travel with ease with new eSIM technology that connects to more global carriers without having to switch SIM cards. The next figure shows how well the display can reproduce dark parts of an image, which is essential when watching movies or playing games in low ambient light. As a real deal business notebook the Latitude E5420 can offer everything that can be wished for when it comes to communication technologies. Since we opted for the Basic-Version, the tested device contains neither Bluetooth or an HSDPA module. The corresponding mini PCIe slots (2x) next to the antenna and the SimCard slot are of course available.Dell Optimizer in Dell Latitude 3520enhances battery life and extends usage time in laptop dell through personalized adaptations, while Express Charge Boost offers a fast charge of up to 35% in 20 minutes or 80% in an hour with Express Charge.

Specifications

New ExpressConnect automatically joins the strongest access point in the office and directs bandwidth to critical applications, wherever you work.\ Turn the laptop upside down, and you will find the ventilation grills and the speaker cutouts. Unfortunately for left-handed people, the heat exhaust is placed on the left side of the notebook.

Audio quality is not where we’d expect the Latitude 5420 to excel. Work laptops often don’t prioritize audio, and this laptop makes no claims about enhanced sound. The firmness of the lid has also been a success. This could only be bent holding the edges to a small extent. The surface consists of brushed aluminum, and can be dented inwards in the middle. Fingerprints may be slightly visible, but do remain, and have to be removed with a cleaning cloth. The base unit could only be bent minimally with considerable strength. The hand resting area and the base plate on the compact chassis lie firmly attached. Merely the area under the optical drive is a weak spot as usual, which dents considerably with the application of pressure. Stay connected at fast speeds of up to 450 Mbps with LTE mobile broadband in your laptop dell. Wi-Fi 6E offers 7 additional channels in the 6GHz band for improved bandwidth and smoother Wi-Fi, especially in crowded areas. Effortlessly connect globally with eSIM technology of Dell Latitude 3520, eliminating the need to switch SIM cards. New ExpressConnect automatically joins the strongest access point in the office and directs bandwidth to critical applications, wherever you work.The benchmark PCMark Vantage determined a score of 4.832 points. This level is below that of older systems with the Core i3-380M ( Samsung RV511: 5.432) or the i3-370M ( Samsung SF510). The cause of this is the low HDD Sub-Score (2.582 points), which should actually be higher with a 7200 rpm hard disc (fast turning). When it comes to the system noise, Dell's 14 inch notebook is definitely acceptable although with some shortcomings. When in an idle state, or when performing simple tasks such as surfing the web, the cooling fan goes off for longer periods of time. We did measure an idle system noise of 32.8 dB(A) though. The noise that was measured by our noise meter comes from a fast turning hard disc (7200 rpm, base noise). The active noise level lies at 33.2 dB(A).
