Business notebook with long runtimes. Skylake, DDR4, M.2-SSD – Dell updates its Latitude 15 E5570. You still get a very good keyboard, simple maintenance as well as a docking port, and Dell also managed to improve the battery runtimes.

Great review! For a lot of people, the reason to go with latitude e5570 instead of Thinkpad T or X series is the optional skylake quad-core processors. So please do review a high end model that comes with either i5-6440HQ or i7-6820HQ, AMD Radeon R7 M370 graphics, PCI-e NVME SSD, 84whr battery and FHD non-touch display. Also, please review Dell Precision 7000 series m7510 and m7710, market equivalents of Lenovo Thinkpad P50 and P70 workstations. Would buy thinkpads if it weren't for constant use of pwms all over their devices. Inspirons and XPS seems to have the same screen flickering issues, though not as annoying as lenovo's low quality IPS displays. Really hope that Dell has better sense to install pwm free displays on latitude and precision lines like the e5570 in this review.
The display is awful
There is a numeric keypad but there is no Num Lock indicator LED. When you want to page down, there is no way to know whether the PgDn key will act as a number or cause a page down. Including an LED indicator for Num Lock would have cost next to nothing, There is no software alternative that I can find. So using this machine is constantly annoying.
They probably left out the led light because it can be annoying when you are watching something. If you look at the Shift Lock light and the mute light, they are very bright.
Ideally, there should be a led, but very dim.
And the keyboard backlight should be modifyable in not three but at least five presets.
Furthermore, I do love this keyboard because of the middle mouse button. Most laptops lack this one, and it comes in really handy when you assign it for you browser: open a link in a new tab. That spares out 3 clicks.
