Latitude 7290 Business Laptop | Dell USA Latitude 7290 Business Laptop | Dell USA
Premium materials: The unibody design provides a clean and seamless exterior with superior structural performance. Finished with soft-touch paint. Dell delivers the Latitude 7390 with a three-year standard manufacturer's warranty. Dell Support will first try to resolve the problem via remote maintenance and hotline on the next business day. If that does not help, you need to send the laptop to a repair center certified by Dell. You can find out about the fee-based warranty extension options here. An amazing display that lasts all day. Built with stunning resolution: The 12.5" HD screen produces life like visuals for remarkable viewing from every angle. The conventional touchpad is large with physically separated keys. The surface is roughened minimally, which ensures easy sliding of even moist fingers. However, it does not react to initial input at the very top edge. The mouse pointer can be moved with pixel accuracy, and fast (but not extremely fast) movements are followed well. You can configure gestures of up to four fingers with the aid of the Windows configuration settings, and there is also a Dell driver menu where some legacy functions can be controlled.
The palmrests and touchpad are cooler than skin temperature with a maximum of 28.4 °C / 83.1 F and are therefore cool to the touch.
Latitude Laptop and Tablet Diagnostic A Reference Guide for Latitude Laptop and Tablet Diagnostic
The average temperature for the upper side under maximal load is 34.8 °C / 95 F, compared to the average of 29.5 °C / 85 F for the devices in the class Office. During idle operation, the fan remains turned off, and the occasional load spikes such as those occurring while surfing do not change this. So we can immediately proceed to the stress test: After Prime95 and FurMark were started, it took almost 15 seconds before the fan started running quietly. Due to technical difficulties, we were unable to run the practically relevant WLAN test this time and therefore needed to rely on other tests of the battery life ( How we test). In the idle test, the Latitude 7390 achieves an outstanding result lasting almost 28 hours, which is almost exactly the same as the predecessor with a battery of similar capacity. The HP EliteBook x360 has 5% less battery capacity, but remains behind the test unit by 16% in the idle test, and 12% in the H.264 test. Continuing, the increase of the fan speed occurred with delays and in distinct steps. After about two minutes, the maximum noise level was reached, presenting itself as a bright whirring that was not too annoying. In a quiet room, it was still audible from a distance of about 5 meters (~16 ft). After reducing the load, the fan continued to run at high speeds for a quite a long time. The Dell Professional Sleeve 15 protects your 15" laptop wherever your busy day takes you. The professionally-stylish heather gray exterior is also water resistant to protect your laptop from the weather.The maximum temperature on the upper side is 43.1 °C / 110 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office. The ergonomically labeled, regular size keys have a slightly concave shape, but all the other keys appear flat. With an easily noticeable pressure point and short stroke, the keys are only slightly cushioned, which accommodates the tastes of the tester. In terms of its satisfying typing experience and high-quality haptic feel, the keyboard is in no way inferior to agood ThinkPad keyboard. We might have said the same for the subdued noise level during typing, but unfortunately Dell has messed up with the frequently-used Space bar, whose clattering is really noisy compared to the other keys.
