Title:
  [Lenovo ThinkPad SL510] Loud beep on resume from suspend

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On my Thinkpad SL510 I get a loud beep when opening the lid to resume from suspend.
  Resuming seems to work as expected, no obvious other symptoms occur.
  The beep when closing the lid sounds normal: Quiet and about 130ms in duration.
  The duration of the loud beep is about 50ms or sometimes even shorter.

  The same symptom has been mentioned on this closed bug report: 
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1447331/comments/14

  I first experienced this after upgrading a freshly installed 14.04.1 to 14.04.2 via the LTS Enablement stack to Kernel 3.16.
  https://wiki.ubuntu.com/Kernel/LTSEnablementStack

  Yesterday a fresh install of 15.10 Beta 2 on the same hardware showed the same symptom.
  Resuming from suspend seems to work in both cases.
  The loud beep was not present in 14.04.1 with Kernel 3.13.

  lsb_release -rd
  Description:	Ubuntu 14.04.3 LTS
  Release:	14.04

  Not sure why it gives 14.04.3 above, since I never upgraded to that.
  It might also be worth mentioning that since installing the LTS
  Enablement  stack I keep getting updates for Kernel 3.13 and also for
  3.16, from which I can choose at system startup in GRUB.
