Latitude 7450 Owners' Thread

Thanks, John. If anyone finds an M.2 that fits and has decent size, 500GB+, please give a holler!

 

I think everyone is looking haha!

Reference post #63 in this thread, where a m.2 SATA was tried and did not work. It must be m.2 PCIe interface and 2242 size.

Sort of like the rainbow unicorn or something...

 

Great PDF describing technical specifications...

edit: added file, link was taken down.

 

I noticed that the 4-cell battery is rated higher (54 Whr) compared to the 4-cell battery (45 or 47 Whr) on the e7440. Does anyone know if they are interchangeable? It would be great to get a bit more juice on the e7440 if they are truly compatible. I hope it isn't something subtle where it doesn't exactly fit, similar to how the E4300 and E4310 batteries were.

 

Just received my 7450 (256 GB SSD, integrated Graphics 5300U, FHD touch) and am very happy with it. Thing i did wrong was order it with the "normal" 8.1 instead of Pro, only to find that out after i installed all my programs and such. Bought an upgrade key and succesfully running Pro now ;-). Apart from that i am very happy with the device (coming from a late 2011 E6520).

However i found out that this laptop is "Ubuntu Certified" (http://www.ubuntu.com/certification/hardware/201408-15385/).

1. Is there a way to get the "Dell" Ubuntu Image for this?
2. Is it in any way possible to run this as a dual boot, when 8.1 is already up and running now?
3. I would like dedicated boot instead of Hyper-V, but maybe both are possible (just like Parallels can use the Bootcamp Image on a MAC to run Windows, so you have dual boot and virutalization).
4. Anyone knows a nice sleeve for this laptop? I've ordered a 15" laptop bag so the laptop will be "loose" in the compartment, so a sleeve would solve that.

 

You can see on pg. 70 of the manual kaspik posted (#93, right before yours) that the dimensions are exactly the same for the 3-cell and the 4-cell.

7450 Battery Specs by jprg24 posted Feb 27, 2015 at 8:55 AM

EDIT: Just realized you were referring to the 7440. Double checked and the battery sizes are identical to those posted in the image above. (see http://partnerdirect.dell.com/sites/channel/Documents/Latitude-7000-Series-Technical-Guidebook.pdf)

 

How lighter is it with respect to the E6420? How it performs? I also owns an E6420 with 8gb of ram, an ssd, and a quad core, 8 threads i7-2720QM CPU and decided to move to this new series.
In my case I was scared the 7450 was not that much lighter than my 6420, so I went with a 7250 (12.5") with a I7 5600U CPU and 16GB of ram but now I am scared I will notice the difference in CPU performance, at least for those jobs (networking simulations) that are CPU bound. Comments (on weight and cpu performance)?

 

Actually i made a typo, i had the E6520, not the E6420. The difference between those to is 0,5 kg and the E6420 is another 0,5 kg lighter compared to the E7450. But i also had the 9 cell battery in the E6520 so for me it is a huge huge difference! Processor speeds are comparable, the i5 i had in the E6520 has the same performance level, however my CPU utilization is now 30-40% lower and everything feels much smoother (both had SSD). Although i use a lot of application simultaneously (average):Word 2013 (1-2 files), Excel 2013 (3-4 files), Skype, Onenote 2013, 10-15 Chrome Browser tabs, another texteditor, 3-4 PDF files (large +/- 5-10 Mb), several other small tools, putty/FTP etc), it are not heavy things i do with it and performance is good.

So i could imagine that network simulation jobs could severely impact processor performance on a "U" CPU. In performance per watt it is a no brainer though....

Check some of those hits, maybe it does not make that much of a difference in the end. https://www.google.nl/search?source...5600U vs i7-2720QM&aqs=chrome..69i57.3104j0j7

 

I know I've been posting this twice in the past, but I'm just curious if this notebook is relatively quiet. I've heard that the fan of the Latitude 7440 could be very noisy and that there were reports of coil whine. Then I read notebookcheck's review where the reviewer felt that the Latitude 7450 fan sounds a little high pitch. So I would certainly like some feedback from the new owners here before I decide to fork out a lot of money to purchase it.

 

I've been working on mine now for a couple of days. To me it is relatively quiet, no high pitch noise or whatsoever. But i have to compare it to a 3-year old E6520. But i would say it is quiet.
