 3 are the vital components of a great business notebook, security, stability, and reliability. The main purpose of such a laptop is to keep your information and data safe, so it doesn't need to best hardware or stunning looks. This, however, didn't stop Dell from giving the Latitude 145420 the Tiger Lake treatment, while keeping the older Comet Lake UCPUs as well. While it isn't the most premium device, it makes up for that by offering excellent battery life and performance. Today we are presenting you with laptop media's top 5 picks about the Dell Latitude 145420. The laptop offers two Sodom slots, one of which is already full. Both of them can handle up to 64GB of DDR4 RAM in total, running at dual channel mode. There is also a single M.2 PCIeX4 slot, for future SSD upgrades. Here is our teardown video, which shows exactly how the upgrade process goes. It gives all the info you need, in order to safely get access to both the Sodom and SSD slots.

Thank you, you're awesome. Where this laptop shined, is with its battery life. While the size of the battery unit won't suggest exactly that, sitting at 63 watt hours. It performed amazingly in our battery tests, lasting for 18 hours and 53 minutes of web browsing, and 11 hours and 49 minutes of video playback. As with all of our tests, we have the Windows Better Performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with. It's safe to say that the laptop can last through 2 workdays, without a charger, no problem. You get a pretty wide I.O., which is split between the left, rear, and right sides. On the left, you will find 2 Thunderbolt 4 ports, along with an optional smart card reader. On the other side, there is a security slot, an RJ45 connector, 1 HDMI 2.0 port, 2 USB type A 3.2 Gen 1 ports, a 3.5mm audio jack, and a micro SD card reader. On the back, you can see a SIM card tray. The laptop comes with a pretty great keyboard plus touchpad combo, which is essential for office work. The keyboard has pretty large keycaps, decently long key travel, and clicky feedback, which is also pretty quiet, making for a quiet office atmosphere. The touchpad is also quite good, having a smooth surface, which offers decent gliding and accurate tracking. However, it does lack dedicated buttons, which would have been appreciated. Dell has you choosing between 2 displays, both with a 14 inch diagonal and an IPS panel. The first one has a 768p resolution, while the second bumps that up to full HD. Our device was equipped with the full HD display, which had comfortable viewing angles, a maximum brightness of 283 nits in the middle of the display, and 263 nits as an average for the entire area of the display. The contrast ratio is quite high, sitting at 1350 to 1. Sadly, the laptop covers only 53% of the sRGB color gamut. The color accuracy was pretty off with the factory settings, with a Delta E value of 6.0. When we applied our design and gaming profile, the Delta E value dropped down significantly, reaching 3.6, which still is nowhere near the standard. Here are the results of our test, with both the factory settings, left, and with our design and gaming profile applied, right.
