Title:
  Asus X200MA Black Screen with Kernel 3.13.0-45 and -46

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Filing this report was recommended to me in the thread to report
  1416849 "Booted into blank screen after the security update..."

  I also use an Asus X200MA with Ubuntu 14.04 and have had the same
  issue i.e. a black screen since the update from 3.13.0-40 to
  3.13.0-45. The update to 3.13.0-46 didn't help so I'm back to using
  3.13.0-40.

  I tried Christopher Penalver's suggestion and upgraded the BIOS to the latest version 504 (from November 2014). With 3.13.0-46 this results in an initially scrambled screen that slowly becomes a white screen after a minute or so. I can still use 3.13.0-40.
   
  $ lsb_release -rd
  Description:	Ubuntu 14.04.2 LTS
  Release:	14.04

  $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date:
  X200MA.504

  Thanks a lot.
