Title:
  ACPI lid and battery info incorrectly reported on Samsung 530U

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  This is from a new Samsung Series 5 (530U) Ivy Bridge ultrabook. The
  ACPI information about battery status and laptop lid status is
  incorrect. They only reflect the state of the notebook at boot, and do
  not show (via /proc/acpi or other means) state changes such as:

  - plugging or unplugging the AC adaptor
  - charging status
  - closing or opening the laptop

  Laptop brightness controls were also affected, but testing with the
  latest Quantal backport kernel (3.5.0-14.15~precise1) shows that this
  has been fixed. The other issues mention above are all still present
  in Quantal as well.
