So, I was able to install the kernel version 3.11.0-999-generic. Once I
rebooted, there was no difference. I changed the GRUB to
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash acpi_backlight=vendor AND
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash acpi_osi='!Windows 2012 AND
OK, so I was able to update my BIOS by installing Windows again.
Rebooted into Ubuntu and nothing happened. Nothing's changed I got this
from the terminal
maxo@Dayman:~$ sudo dmidecode -s bios-version sudo dmidecode -s

Christopher, I don't know how to update the BIOS on a full Ubuntu

to do it? It came in a zip file.
