Qwick question :
I saw the specifications of the BH156HW03 screens, and it don't specifie that it's a IPS or TN models. I think it's TN because the datasheet specify that the display mode are "normally white". On the IPS screen, it is on "normally black". Anyone can comfirm my position?
If it is write, it is possible to modify the specification at the test?
Thanks

Why do manufacturers even bother releasing $2000 laptops with screens so dim you question which department made a mistake...

I am wondering what is the difference between Precision 3530 and this? Same body, same motherboard and actually same everything by the looks of it, just different model name? Ah, only Quadro graphics in Precision? I love my Precision, it is silent and cool under usual workloads, and can handle games when I feel like a bit of gaming.

I bought this computer. Its horrible speakers on it! And the backlihton keybord is very cheap... Apart from that good laptop

Fan Noise

We also got the 5591 in the Company. Unfortunately, if it is connected through Thunderbolt the fan is always on, even when on idle. When you believe the dell forum, it is because the thunderbolt chip on the mainboard is getting too hot. Seems dell forgot to include the chip into the cooling system. We are disappointed because in a quiet office to do not want to hear the notebook for "office work"s.

Hey Thanks so much for the wonderful and detailed  advice, Panko ---- I really do appreciate it. Now I feel I can configure the laptop with !6 GB RAM without having to worry about heat issues.

Actually, I wasn't considering adding a mechanical HHD , just ordering  a 1 TB Solid State Drive [I had thought that was an option on the Dell Features and Technical Specifications page, but perhaps I am mistaken]

But maybe your suggestion of 512 SSD and then adding a more storage with an external Hdd through a usb3.1 interface is more heat friendly to the 5591 chassis (as well as economical) ???

Many Thanks Once Again for your great insight !

" I guess the reviewer was in error when he indicated that the 5591 had 2 heat pipes."
-> I think if you choose model with dedicated gpu you will receive the second heat pipe. All other variants of the 5591 have only one heat pipe.

"..  should I therefore limit the configuration to 8 GB Ram due to heat concerns? "
-> No. Just go for 2x8gb.
The pipe dissipates the heat from cpu and if you have gpu, from both of them. The heat from RAM is very small and you can see that RAM modules dont have any pipe over or around them.

"..answering medical emails as well as downloading music videos."
-> i5 8400 + 2x8gb will be more than powerful for your purposes.
Only for the case when downloading videos - I am not completely sure if 5591 can have NVMe SSD + mechanical HHD at the same time, because from what I can see those ports may be physically overlapped each other. For the NVMe SSD must go, but for the hdd you can just take external hdd with usb3.1 interface..

Thanks so very much, Panko for your video suggestion and reply--- I guess the reviewer was in error when he indicated that the 5591 had 2 heat pipes.

A follow-up question if I may :

Although I would really prefer 16 GB Ram so as to avoid a future upgrade a few years from now , given the video tear down shows there is only 1 heat pipe on the 5591,  should I therefore limit the configuration to 8 GB Ram due to heat concerns?  I would not be doing any gaming or intensive applications on the laptop, although I might be on the 5591 for  ~ 6 hours/session answering medical emails as well as downloading music videos.
Also, as I know classical/jazz videos can over time take up a lot of space, I might want to consider a 1 TB ss rather than the 512 GB----but again, I have heat concerns given the limited amount of space within the 5591 chassis.

Any  thoughts or comments on this I would truly appreciate.

Thanks once again for your expertise!

Would the chassis of the 5591 configured with a i5-8400H processor, no touch screen,  512 GB SSD, 16 GB ram  WITH INTEGRATED GRAPHICS [instead of the dedicated graphics] still contain the 2 separate heat pipes as indicated in the review????

No, it has only one heat pipe. In youtube you can find and watch the video "Dell Latitude 5591 Unboxing Teardown" / it was published on Jun 16, 2018 :).

QuoteIt is useless and mutilates keyboard ergonomics. Nobody likes it.

It is useless for those who are not a software developer or do not know how to use this unit for efficient navigation, insert operations into 2 hands. I do not care about the touchpad on any laptop, I do not use them, their presence or absence does not bother me at all, because connects the radio-mouse, which is more convenient at times. But without an additional digital block, efficient writing of the code is not possible in principle, as is doing business in a number of other areas of activity. Using keyboards without them is simply impossible. This ugliness is complete. Therefore, many developers ignore the XPS line and similar options 15.6, basically a truncated keyboard is needed only for "effective" managers and simply for consumers of content, but not for real professionals, writing a lot of code, classes, scientists and mathematicians.

XPS have bad keyboard. No digital block.

Keyboard is subjective. Tons of 15"+ laptops out there with a numpad but many including myself prefer a centered keyboard and touchpad thus the unique appeal of the XPS 15. Degree of margin for a keyboard is also smaller than majority of other hardware meaning average isn't too far off from the best or worst. The XPS keyboard feels maybe average and Latitude 5000 although slightly better is far from top keyboards such as Thinkpad X1 and Surface. Not to mention the layout on it was already awful to begin. On the contrary layout on XPS seems to have improved by the looks of the 2 in 1 9575.

Not just the screen - performance, speakers, webcam, touchpad - they're all dreadful for this price in this age.

Again poor and dull IPS. Dell...save on every cent, although people do not need such cheap IPS and they are ready to pay  +30$-40$ for normal IPS (90%+ sRGB, 300+ nit). Some kind of dominance over all manufacturers, a natural conspiracy in the sector of 15.6" laptops, because in the sector 14" and 17" there is no problem to buy a cheaper 1000$ laptop with high-quality IPS. Marketers are completely off the reel... >:(

XPS 15 9570 configured to i7 and 1050 Ti from Dell's "Business" store retails at 1,400 USD which is a grand less than this but comes with better hardware. Go figure.
