I am using the A18 bios, and the release date according to Dell US website was 04 May 2016, so I think it is the latest bios.
The output of the "sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date" is: martyn@martyn-Latitude-E7440:~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date [sudo] password for martyn: A18 04/28/2016 martyn@martyn-Latitude-E7440:~$ -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1513914 Title: Dell E7440 touchpad jumps position Status in linux package in Ubuntu: Triaged Bug description: Ubuntu 15.10 - Dell E7440 touchpad works correctly when freshly started each time; but after some time running the mouse pointer starts to randomly jumps position when I try to use the touchpad.
