Title:
  ubuntu 1404_HWE_EOL kernel breaks Thinkpad T530 keyboard backlight
  operation

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  System: Lenovo Thinkpad T530 laptop
  OS: ubuntu 14.04 LTS, kernel 3.19.0-66-generic 64bit
  lsb_release -rd
  Description:  Ubuntu 14.04.5 LTS
  Release:      14.04

  With the above configuration the keyboard backlights and screen-top
  illuminator work as they are supposed to.

  In August I received the 1404_HWE_EOL update popup. Image taken today is 
attached.
  I installed the ubuntu 1404_HWE_EOL which installed (I think) some 4.4 kernel.

  After installing, the keyboard backlights and screen-top illuminator
  come on without hitting the special keys. When it returns from screen
  saver when I hit the return key these lights come on also.

  If I reboot to the old kernel all is well. So something is broken in
  the kernel that is installed with the 1404_HWE_EOL

  So I deleted this new kernel for now.

  The popup comes up constantly for almost 4 months now, many many times
  per day. This is a huge annoyance.

  More seriously is that no other updates are coming in. This poses
  security issues at a minimum.

  Accepting the update causes the backlights and screen-top illuminator
  to go on with every screen saver operation which is just as annoying.

  I hope someone can fix this so I can move forward and stop the annoyances to 
boot.
