Re my comment above - I should have said Nouveau Drivers - It is an NVIDEA Card.
I am referring to using the PRIME option to switch from Intel to NVIDEA card

Title:
  Acer Aspire M5 481T consuming power while turned off! Battery drains
  with system halted!

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Guys, I'm facing this problem just since I installed Ubuntu 15.04. The
  laptop came with Windows 8 installed and this problem didn't exists
  there. Everything seems to run just fine, but when I turn it off with
  50% of battery for instance there is no energy after some hours and I
  can feel that the laptop is a little hot, but there is no noise like
  anything was on.. What could be happening? I've searched for some
  solution, already tried to include some options in grub config like
  noapic, nolapic, irqpoll, acpi=off and others without solution. Also
  tried to check WOL but it's ok too. What could be happening? How to
  solve this problem?
