Title:
  [Acer AO 751h] Laptop requires a hard reset to recover from  suspend
  state

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Description:	Ubuntu 14.04.1 LTS
  Release:	14.04

  Since update to Lubuntu 14.04.1 from lubuntu 13.10, the laptop is not
  able to resume from suspend anymore. I've checked this happens runing
  lubuntu 14.04.01 LiveCD too (but not with the LiveCD of previous
  version of Lubuntu). If I start  the OS with the previous kernel
  3.11.0-26 I have not the problem. But starting with kernel 3.13.0-32
  or  3.13.0-34 it is there.

  If I suspend the laptop closing the lid, or from the menu, pressing
  the power button (to show the exit menu) or running sudo pm-suspend,
  the laptop get suspended, the screen will off, and the power button
  led blinks as expected. But then it is not possible to awake again
  neither pressing a key or pressing the power button. If in that state
  I try to power off keeping pressed the power button, that still does
  not work: the blink led still blinks and nothing happens. The only way
  to recover the system is  removing the battery and turning on again.

  That I expect:
  After suspend the laptop, I am able to resume it again, just pressing a key, or pressing the power button.

  I've tried starting with "acpi_osi=linux" but didn't help. (anyway,
  that was not necessary with the previous kernel/OS version).
