Latitude 7480 keyboard issue (mostly missed keys)
Hello,
I'd like to ask if i am the only one with some issues about the Latitude 7480 keyboard (bios 1.7.3, was the same with 1.8.1 too).
if i type normal (e.g. not very slowly) some keys are missed:
if i have to type "system" it produced sytem (the s is missed). (same behavior is observed in uefi shell, or bios add boot options)
if i have to type cat .. |grep , usually the result of typing is ...|Grep (like i am keeping pressing the shift key..)
if i have to use ctrl-shift-c / ctrl-shift-v (shortcuts for copy/paste) usually i just get C and V (e.g. ctrl missed)
using shift-ctrl-tab (to scroll between tabs / windows backward) in most cases produces just ctrl-tab (forward scroll)
this happens in linux, both console and Xorg, as well in windows (virtualized guest) and also in bios.

I can definitely vouch that this keyboard issue is occurring. We've ordered a few batches of 7480's for work, and I've been able to reproduce this issue on every single one of them. I can open up a word pad, type the same word over and over again, and some letters will appear out of order or skipped. I'm a pretty fast typer, so I had some of my coworkers try it--anyone who typed quickly ran into the same issue.
The computers were updated with the latest drivers/bios. I've been meaning to open up a case with ProSupport about it, hopefully it's something that can be fixed with a software update.

Yes, this is definitely an issue, and it seems not confined to the 7480 because another thread was created about this recently for another system. I notice it most on my own 7480 when I type one key, then another, and then the original key again, e.g. "ana", "efe", etc. I didn't realize how often that pattern occurs in the English language until I got this system, and it's absolutely infuriating to me because I type 140 WPM, so I see it all the time. This behavior does NOT occur with an external keyboard attached to this system.
My guess is that either this is related to keyboards on newer systems having changed over to S-e-r-i-a-l IO from the previous USB or even legacy PS/2 interfaces, and either there's an inherent issue with that new interface or (more likely) Dell just has a subpar keyboard controller for this new interface or something. I really hope this gets fixed in future products, because I'm now going to test Dell systems I'm considering for this issue before buying. My 7480 is a work system and I haven't been able to get a different model approved for this issue, but no way would I spend my own cash on a system with this issue. Ironically though, I spend a lot more time on my work system....

Yup, this is definitely still happening, even with all the latest drivers.
Perhaps someone from Dell could chime in? Is there a fix in the pipeline? It makes typing an unenjoyable experience on this computer.

Hi,
I spotted the same issue with keyboard, missing os misplaced letters during fast typing.
I checked it more detailed, it looks that problem exists in Windows, Linux and in BIOS too (there is input field in BIOS that you can check), which means that it is not a system or system drivers issue, but hardware or hardware's firmware.
I also found out how to reproduce it easily, so you can check if problem is fixed without trying to type for a long time. For me it's enough to type two letters with one hand in exactly the same time (in my case "a" and "t", but it does not matter which letters you are using) for 10 times. Then you can count how many letters were produced. In my case it's about 14-16, should be 20.

I raised that issue to Dell using NYB, they sent me 3 technicians, which replaced motherboard, keyboard, palmrest, but problem still exist. So I guess it's something in 7480 model, maybe firmware of keyboard/motherboard. Next they ask me to send that laptop to them to Dell service, so they can check and fix my issue. After 10 days they send me back my laptop with replaced motherboard, keyboard, palmrest and still same issue, saying that it was resolved.

Hi guys,
There's been a BIOS release that should resolve the keyboard issues you've been seeing.
http://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverId=5P09H
Let us know how you get on.

I'm happy to confirm that this BIOS release fixes the problem with the internal keyboard.
Works fine now. Thanks

I have exactly the same problem with a dell latitude 7490.
It seems that there is no bios update yet for this model to fix the issue.
To dell support: Do you know if a fix is planned for this model?
Thanks.

Hi raf2222,
Can you send me a PM (click on the envelope at the top right of the page) with the service tag and confirmation of which BIOS version you have installed? Is it just one system you have seen the issue on?
Thanks

Thank you Alasdair,
I sent to you a PM with the required information.
I however do not have any other 7490 model in the office to test this bug.
We have a lot of 7480 models and they all have the keyboard issue which is solved with the latest version of the BIOS.
The problem observed on the 7490 is exactly the same as the one observed on the 7480 (same behavior for missed keys)

Hello, 10x for your cooperation and apologies for late reply.
Updating BIOS to 1.9.3 helped a lot.
Updated almost immediately after release, so the below mentioned opinion can be considered real world one (e.g. it is based on enough long term experience:) )
shortcuts ctrl-shift works as expected, i am happily using ctrl-shft C/V/tab and they works properly. (10x for that). Also i did not see missed keys
There are still some minor issues when typing (to be honest the speed of typing is above the average, probably can be considered very fast)
reorder (swap) of keys.
typing "grep" sometime produces: "grpe"; typing "very" sometimes produces "veyr"
ghost keys.
typing "grep " (mention the space) sometimes produces: "gr'ep ", "gr'e p", "gr'p e", "gr' ep".
e.g. the "'" (character ' ) is the ghost, also reordering is seen too.

I can attest that I am experiencing the exact same issue on my 7490 (e.g. typing "init" results in "int"). This is occurring on BIOS version 1.2.8 (and it was also happening on 1.1.6).
My fingers are crossed for a BIOS update to fix us 7x90 folk, as right now the typing on this laptop is unacceptable. Thanks in advance!
