Erik Nasaroff, as per
http://support.lenovo.com/en_US/downloads/default.page?selector=expand
an update is available for your BIOS (2.54). If you update to this, does
it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

Title:
  [ThinkPad W530 2447] Brightness keys don't work as expected on

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  First I could only change the brightness level by one step. (From 100% to 95%.)
  After I added 'GRUB_CMDLINE_LINUX="acpi_backlight=vendor"' in /etc/default/grub the keys work as expected, but the notification showing the brightness level displays the wrong value.  Attached a picture with max brightness.
