LATITUDE E3450

Hi

I got a brand new latitude E3450 with ubuntu pre-installed. However there is a very serious problem with this configuraton. A keystroke randomly gets stuck and the character is repeated unless i press another key. This hapens  5-6 times a day as far as i observed, this is becoming  very very annoying especially while writing a thesis or an article. 

Spending some time googling i came across this  ubuntu forum thread. It appears exactly the same issue but for E7450 and has been solved with a bios update....

askubuntu.com/.../dell-latitude-e7450-repeating-keystrokes-issue

My BIOS version is :

>sudo dmidecode -t bios -q
BIOS Information
Vendor: Dell Inc.
Version: A03
Release Date: 11/27/2014

After all, I think 3450 has the same problem but remaind unfixed. Does anyone know if Dell is to release any update for this ? This is a very serious issue :(

Many thanks in advance 

Cheers
