Title:
  Power button not recognized (no ACPI event produced)

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  On a Dell Inspiron 1210 ("Mini 12"), the power-button is not
  recognized with recent kernel versions.  I know it *is* recognized
  with the linux-image-3.11.0-23-generic kernel (I did not test out
  several images to determine exactly where the regression/bug was
  introduced).  The BIOS of the Inspiron is version A04 (the latest
  version available).

  To reproduce:

  1. boot normally with a "bad" kernel version (e.g. 3.13.0-32-generic, as provided in Ubuntu where the kernel is configured with the CONFIG_ACPI_BUTTON=y option)
  2. switch to a console and log-in (or alternatively, open a terminal after logging in to a desktop env.)
  3. run the "acpi_listen" executable from the terminal
  4. press the power button.

  With a "bad" kernel version, nothing will happen (no text will be
  printed to the screen).  With a "good" version, you will see some text
  indicating that an event occurred.

  Consequently, with a "bad" kernel, if you suspend the machine via the
  power-off menu option, there is no way to resume (I also tried to
  close and open the lid after suspending, to no avail).
