There seem to be a few different Latitude E5580 :
At least the two first seem to have exactly the same specs but different prices. Why?
Under "for the home user" (translation from Swedish, http://www.dell.com/sv-se/shop/cty/sc/laptops?c=se&l=sv&s=dhs&~ck=mn) Latitude is not mentioned. Why?
Does not Dell have e-mail support for product questions? Why not in that case?
Thank you for pointing that out, I didn't see that.
My previous experience from Latitude is the E5550 that I use at work. It has one of the nicer keyboards I have used and has a good overall feel if you ask me. I am doing some software developing at home and am looking for a solution to use both for just that, either sitting by the desk or having the laptop with me somewhere else. I guess a dock would be suitable then. The dock I have at work is however too big, but the WD15, or even the wireless dock (love the absence of cables) seem like more compact solutions. I have a Dell U2412M monitor; it does not have a HDMI connection, but a VGA, DVI, and DisplayPort ones. I guess that the DisplayPort one could work best together with the wireless dock? (the review I have seen is https://www.youtube.com/watch?v=JeUU1PIyq-4)
I've used the E5550 myself and yes its keyboard is one of the better versions out there. Dell makes solid business-grade keyboards for their Latitude models; the quality of the keyboards in their other product lines is not as consistently, although they have been getting better.
I've never used a wireless dock, although it's not something I would ever consider. First, I want a dock that charges my system, and second I wouldn't want a wireless connection to a device that would have things like an external hard drive attached. If you want to consider it, that wireless dock uses the WiGig standard, so you would also need to get the WiGig option for any system you want to use with it, and I don't know if the 5580 is even available with WiGig. But I personally would recommend either the WD15 or better yet the TB16 dock, although the latter would require you to get Thunderbolt 3 on your system, which is optional on the 5580. The WD15 can do up to dual 1080p displays or a single 2560x1600 display (or single 4K only at 30 Hz), whereas the TB16 can handle up to dual 4K displays at 60 Hz and even some triple display configurations. Note that with either of those docks, to use them with the 5580 you'll need the version that comes with the larger of the two available power supplies, so for the WD15 you'll need the one with the 180W AC adapter and for the TB16 you'll need the one with the 240W adapter. Good luck!
How is the compatibility between the WD15 and Latitude 5580?
http://www.dell.com/sv-se/shop/accessories/apd/452-bccw?c=se&l=sv&s=dhs&cs=sedhs1&sku=452-BCCW#polar... - WD15 does not say it is compatible with E5580
Also, it seems I need to order directly from Dell to get the optional Thunderbolt 3 port, but the web page does not seem to work:
Additionally, I first got a lot of hits when I searched for "Latitude E5580", then I only got one and now I get none...
When googling I found
but there I could not find _any_ laptop with 512 GB SSD, which I found from the start...
First, note that the model name is just "Latitude 5580", not E5580, so that may be affecting your search results. The "E" was dropped with the xx80 models because that letter indicated the generation of underside docking connector on the system, and the xx80 models removed the underside docking connector and switched to USB-C and Thunderbolt instead.
For WD15 compatibility, the WD15's FAQ page here lists the Latitude 15 5000 Series as compatible, which would include the Latitude 5580. However, I remember another thread saying that the article was wrong about only needing the 130W adapter version if you want to charge the system that way; the customer found out that they needed the WD15 with the 180W adapter instead, so you may want order that instead, otherwise you can try ordering the 130W but you want to try to save some money, but you might have to return it if it doesn't work properly.
For Thunderbolt and the 512GB SSD, I'm not sure what to tell you about not being able to order it. Different regions have different online stores, so what I'm seeing in the US won't match what you're seeing somewhere else. But in the US, I see 22 different preconfigured options for the Latitude 5580, and some of them allow customization, and in those I can add Thunderbolt and a PCIe SSD up to 512GB. Some other Dell systems include 1TB PCIe SSDs, but I don't see that here. In your case it could be a temporary glitch or it's possible that options for the 5580 are being reduced since the Latitude 5590 has been released, but fyi the 5590 does not support booting from the internal hard drive in Legacy BIOS mode; it requires UEFI booting. That's not an issue for most people, but I just wanted to let you know. The 5590 also does not support Windows 7 at all, whereas the 5580 will support Windows 7 if you order it with a 6th Gen Core CPU rather than a 7th Gen.
One more point I forgot to mention about docks. If you go with the TB16, you'll need the version with the 240W adapter, not 180W. Basically both the WD15 and TB16 are available with 2 different AC adapter capacities depending on the power requirements of the systems you'll be using them with. The WD15 can be ordered with a 130W or 180W adapter, and the TB16 can be ordered with a 180W or 240W adapter, because the TB16 dock itself consumes more power than the WD15. A Latitude 15 5000 Series model needs the higher-wattage option of whichever dock you choose so that there is enough power available to meet the system's requirements after the dock has reserved the amount of power that it needs for itself and any external peripherals you might connect to it. Therefore if you go with the WD15, get the 180W adapter, but if you go with the TB16, get the 240W adapter.
Thanks a lot for the detailed information!
When searching for 5590 I could only find there are versions with 8GB RAM inside - 16GB does not seem to be selectable. Any idea why this is so? Or have I just not found the right web page?
