Hi Christopher,

I am sorry for the delay, seems like I did not read my email for over two weeks...

I have just tested with "Ubuntu 16.10 "Yakkety Yak" - Alpha amd64 (20161008)". No changes and exactly the same dialogs as described in the original report.

I have also updated the desktop to 16.10 (alpha), no improvement either.

Let me know how how can I help further. This regression is really annoying... I have to go through grub and BIOS settings each time I am taking the notebook off the docking station.

As a workaround I had to disable optimus in BIOS. That also requires putting the following line into /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="thinkpad-acpi.brightness_enable=1 acpi_backlight=vendor"
Otherwise the machine hangs at boot in kernel. These kernel parameters need to be removed each time I switch BIOS to internal graphics in order to get reasonable battery life.
