Title:
  Thinkpad x230 rapidly increasing Load_Cycle_Count on battery

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  When running my Thinkpad x230 on battery, the Load_Cycle_Count
  increases at a high rate: about 10-15 load cycles per minute. I
  discovered this issue in a quiet room, where I could hear the clicks
  (or "death rattle", as I've come to think of them).

  The following commands will stop the load cycle problem:

  sudo hdparm -B 254 /dev/sda
  sudo hdparm -B 255 /dev/sda

  However, it is difficult to keep the system from reverting back to the
  load cycle problem.

  Steps to reproduce:
  1. Boot the laptop on AC, then unplug the power. In a quiet room, you can hear the clicks begin soon after you unplug.
  2. Boot the laptop on battery. Even with "apm = 255" uncommented in /etc/hdparm.conf, the laptop will burn through the load cycles until I manually perform the hdparm command.

  I had limited results with an upstart job that did the hdparm command
  -- but it wasn't a complete, reliable solution. It didn't catch the
  AC-to-battery power transition, for example.

  As a result of this issue, my hard drive is probably going to meet an
  early demise:

  193 Load_Cycle_Count        0x0012   090   090   000    Old_age
  Always       -       107908

  Please help-
  Casey
