There is new release or BIOS for XPS 13 9343 laptop. Finally no repeating keystrokes apparently! I am so tired of these and so happy to be able to have only typos I get from my own fingers :)

Upgrading to BIOS A07 on Ubuntu

• Go to the Dell support page and download the sucker
• With sudo put it to /boot/efi dir
• Restart and press F12 to get to upgrade window
• Follow Instructions to Upgrade your BIOS firmware

And here we go – typing is back to normal AT LAST.
