I've appeared on CBS News, in USA Today, and at many other outlets to offer analysis on breaking technology news. In terms of display options, it is a bit disappointing that Dell still offers a 768p TN panel as a default. It is strongly advisable that you stay away from it, and go for the IPS variant. We got the non-touch option, and it is a pretty budget-friendly offering, as you will see later on. Dell Latitude 15 3520’s IPS panel has a Full HD resolution, comfortable viewing angles, and a good contrast ratio. Unfortunately, it covers only 53% of the sRGB color gamut, and it uses relatively low-frequency PWM up to 89 nits. Thankfully, the more sensitive users can take advantage of our Health-Guard profile, which completely eliminates the issue.

The maximum measured brightness is 348 nits (cd/m2) in the middle of the screen and 321 nits (cd/m2) average across the surface with a maximum deviation of 11%. The Correlated Color Temperature on a white screen and at maximum brightness is 6610K (average) – almost matching the 6500K optimum for sRGB. Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day. As we said, the Latitude 15 3520 boasts a simplistic design. It is entirely made out of plastic, which is matte and grippy on the top, base, and bottom covers, while the sides are glossy. Structurally, the laptop is not very strong. Unfortunately, there is some flex pretty much everywhere. Interestingly, the lid is tougher than the base in this aspect. It is also rather thin at 18.06mm and weighs 1.79 kg.SupportAssist, previously called My Dell, provides system updates, detects issues and sends you alerts based on your device, which makes solving and preventing problems easier than ever.

The section below provides links to articles that contain information about the different hardware on your system. They can help you to troubleshoot any problems that might be identified by the above diagnostics. There are also general "How to" articles that can help with tasks, for example like updating the BIOS or upgrading a hard drive. AC Adapter and Battery Dell Latitude 15 3520 comes with a Full HD IPS panel, model number Panda VNCT2-156DL02 (NCP0057). Its diagonal is 15.6″ (39.62 cm), and the resolution – 1920 х 1080p. Additionally, the screen ratio is 16:9, the pixel density – 142 ppi, their pitch – 0.18 x 0.18 mm. The screen can be considered Retina when viewed from at least 60 cm (from this distance, the average human eye can’t see the individual pixels).

Dell covers the Precision 3520 with a one-year warranty, though also offers its business-focused ProSupport service plans as optional add-ons. CPU Compromises

Interestingly, even when the Performance mode is applied from BIOS, the processor can’t seem to pass the 3.00 GHz mark under extreme load. Thankfully, it maintains a relatively high frequency after long periods of time. Comfort during full load
