  CPU stuck on minimum frequency after resume from suspend and unplugged

Status in “linux” package in Ubuntu:

Bug description:
  This happens on a Dell Latitude E6540 (4th gen core i7 CPU).

  Steps to reproduce:

  1) normally boot the computer and make sure  everything works as expected (i use the ondemand governor)
  2) suspend
  3) make the computer is unplugged and resume

  Expected behavior: cpu should work normally
  Actual behavior: cpu always stays at minimum frequency (in my case 800 MHz)

  If i resume from suspend while plugged to the AC charger, everything
  works as expected.
