The only way I can wake up my laptop (HP Elitebook 8460p) from suspend is by pressing the power button. Neither the built-in keyboard/mouse nor the external ones (connected via USB) wake the laptop up.

Things I already tried:

  • Enabling the USB devices in /proc/acpi/wakeup.
  • Checking the bootlog to find out the /dev paths of the USB mouse/keyboard, then:

    udevadm info -a -p $(udevadm info -q path -n /dev/input/mouse2)
    

    I then checked for every device in the list using:

    cat /sys/devices/.../power/wakeup
    

    if it is possible to enable it, and if so, I do that.

  • I have enabled wake on USB in the BIOS.

Here some outputs you might need:

This is a little bit out of my element, but it sounds like you're laptop is going into hibernate instead of suspend. –  bahamat Jun 14 '13 at 4:26
