ok… I was trying to install the wrong BIOS
the E1781IMS.310 is for i7-5xxx while mine is i7-4720 . So I needed a 
E1781IMS.310T

$ cat /proc/cpuinfo | grep "model name" | head -n 1 | cut -d ' ' -f 5 | cut -c 4
4

the bios is upgraded !but I still have this issue. I tried the 349.16
free driver instead of 352 but the issue is still the same.

$  sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
E1781IMS.10T
