Mint 17.2 Wakes Up a Few Seconds After Suspending

By | November 21, 2015


After selecting “Suspend” from the session dialog, the computer goes to sleep and wakes up on its own a few seconds later.


Probably cause it network adapter hardware, driver or firmware.



Troubleshooting Steps:

  1. Unplugged USB mouse, keyboard and network cable
  2. Restarted PC
  3. Checked system log -> does not indicate what woke the computer up (“ACPI: Low-level resume complete”)
  4. Checked suspend log -> /var/log/pm-suspend.log
  5. Disabled wake up capable devices
    1. List wake up capable devices -> acpitool -w
    2. Disable particular device -> acpitool -W [Device No.]
    3. In my case, disabled GLAN, EHC1, EHC2, & HXC
  6. Removed e1000e module, shutdown VirtualBox virtual machines (Win 8.1 IE 11 Virtual Machine may be a cause), then re-added the module
    1. sudo rmmod e1000e
    2. double-check that GLAN is still disabled with acpitool -w
    3. Computer will now sleep without waking up.
    4. sudo modprobe e1000e
  7. Re-enable wake up devices with acpitool -W [Device No.]
  8. Restarted computer. Launched various apps (Chrome, Firefox, Virtual Box + VMs) and tried to suspend PC. Works for now.
