New Dell Latitude 5590 - supports only 2x pci-e lanes for Nvme M.2 slot.
It limits ssd performance to only 1700 MB/s. Crystal mark test: prntscr.com/imt60q
Dell business partners advertise and sell SSD M.2 Nvme drives like Samsung Evo 960 as add-on. Be carefull it will work only 50% performance, shame on Dell! Its 2018!

I need to use a CD Rom Drive.  Does this have such an input device? The Dell Latitude 5580 (i5-7200U ?

@Jeff Brody: @joschh:

Much cheaper laptops sport FHD IPS displays with around 350 nits of brightness, 1300:1 contrast ratio, 95% sRGB and 70% AdobeRGB color coverage. MBPs and Surfaces have over 500 nits, 1800:1, and impeccable color gamut.
And here's a batch of "professional" and "business" laptops from Dell, HP and Lenovo that are more than x2 as expensive as the cheapest quality laptop, that only averages at 250 nits, 800:1, and 65%/40% on a same display config, with 250Hz PWM flickering to add to the insult.
(I don't know much, but my guess is that the Latitude 5580 and Precision 3520 use different displays, as they have in the past)

I'm not saying all business laptops have crappy displays, but most Full-HD non-touch IPS displays are garbage, and for some people, anything else isn't a viable option at the present.

Just got mine and I'm quite pleased.  FHD display completely satisfactory.   Not sure why the comment "worst display" .. far from the "worst" IMO.

Why the worst? Very low maximum brightness, low real viewing angles, extremly wrong colors - white is gray, gray is black, ... I had to change contrast, RGB brightness ... by at least 30 percent to partially fix the color. If I compare all low cost HD lenovo, acer ... displays with 5580 FHD, the 5580 FHD is way the worse. If someone really want to buy the latitude, the best is to buy previous model - 5570 because it has much better display. Btw. dell even did not mention nontouch FHD display nits (only the touch version) in their product sheet ... one could ask why  :)

"The worst display I have ever seen!"

Please be a bit more specific. What was that bad about it?
If it comes with a low quality display, it's probably not the same as in Precision 3520
like Benjamin stated. The 3520 display test results look quite good except of PWM flickering (even it's on high frequency).

Why? The brightness is low?

I just returned 5580 with FHD nontouch display. The worst display I have ever seen!

Is the screen supplier depends on country?
For FHD screen, I learn that is AUO, but on a website I see LG...
And for LG, it seems to be less that the specify 300nits.

We have just tested the Precision 3520, which uses the same chassis as the Latitude 5580: https://www.notebookcheck.net/Dell-Precision-3520-i7-7820HQ-M620M-Workstation-Review.224112.0.html

The Latitude 5580 with FHD and HQ CPU would be nearly the same, main difference is the GPU.

When we will see the other SKU of this laptop. I want to know how this laptop will work with FHD IPS panel and i7 (U or HQ).

Best Regards!

I am looking forward to buy this laptop, but before that I really want to know if I can put both a 2.5 HDD/SSD and an 2280 M.2 SSD at the same time. Is it possible ? If not, can this laptop boot from the 2242 M.2 slot ?

Strange that review says nothing about TDP configuration of CPU.

from reviews of X1 Carbon and direct competitor Thinkpad T570 we know they make use of configurable TDP feature, to raise TDP from 15 to 25 Watts.

Was it too difficult and time-consuming to run Intel XTU utility to check these numbers?

Also would be interesting to confirm that Precision 3520 use TDP-down from 45W to 35W.

QuoteA total of three internal storage bays are available in the form a 2.5-inch SATA III bay, an M.2 2280 slot with NVMe support, and an uncommon M.2 2242 slot.

So what would be the third storage bay, unless it's meant the slot for the WWAN card? In that case it can probably be used for cache only when using 2.5" HDD.

As far as I recall E7440 was one of the very few models that had the option to use the m.2242 slot for a "bootable" SSD. On most other models it was available only as cache drive.

This http://en.community.dell.com/support-forums/laptop/f/3518/t/19992358 suggests the same.

One suggestion for reviewers is to check what storage combinations are possible. Dell is specifically infamous about it, that it seems like more than 1 disk is supported but in reality it's not. Either one disk physically blocks the other, or second disk can only be used as cache.


BTW, it's very frustrating to read these Dell reviews on low-end SKUs. I know that editors may not have a choice here and they review whatever piece of hardware is made available to them but I wished it could be models that 'average' home user is likely to buy. I have the feeling that when business models are reviewed it always goes to extremes. Either it's 2500€+ laptop with UHD screen and Xeon processor, or a low-end one with 768p screen and HDD.

I am really waiting for the Dell Precision 3520 review and I hope it won't be the low-end model again.

@dthrp: Thanks for all the effort! I already knew some of the E5570 reviews but it seems like the Latitude 5580 uses a different panels, so I can't rely on these display tests.  :-\

@Benjamin: Sadly the Precision 3520 isn't the one for me. According to other reviews the display quality isn't pretty good.
