My system is ASUS N56VJ. The suspend feature works the first time if I sudpend by closing the lid/or specifically selecting to suspend form the settings menu(top right gear button).Lateron it just does not suspend..

Secondly if i press the hardware power button and choose to suspend from the poped up menu, i can suspend as many times i want.. same is the case if i suspend using

sudo pm-sudpend

it suspends everytime.

the difference in the way suspend happens can be juged by the output of

acpi_listen

while suspending using the above different options.

i have logged the acpi_listen optput as:

 1. button/power PWRF 00000080 00000001 @@@@SUCCESS (using power button)
 2. button/power PWRF 00000080 00000002 @@@@SUCCESS (using power button)
 3. button/lid LID 00000080 00000001    @@@@SUCCESS First Time! (closing the lid)
   video GFX0 00000080 00000000     @@@@ comes up when lid is opened
 4. button/lid LID 00000080 00000002    @@@@ Failure! 
   video GFX0 00000080 00000000     @@@@ comes automatically as suspend fails
   button/lid LID 00000080 00000003 @@@@ and this follows immediatelly (not sure why this comes two times)
   video GFX0 00000080 00000000     @@@@ and this too.
 5. button/power PWRF 00000080 00000003 @@@@ Failure! now suspend from power button fails too until reboot
 6. button/power PWRF 00000080 00000004 @@@@ Again Failure! now suspend from power button fails too until reboot

the complete dmesg log is attached with the important messages posted here synced with above 6 attempts to suspend:

full dmesg log

Important points 1) what i can fetch out here is that when i use the power button to suspend from the popped up menu, the command executed to suspend is

execute_shutdown_or_sleep

while closing from the lid im not sure what command gets executed for sleep from the above logs.

Secondly, i am only prompted for a password on waking up when i do that by closing the lid/or selecting suspend from the power menu in top right corner,and not when i do it using sudo pm-suspend or by using the suspend option in popped up menu on pressing h/w power button.Maybe this is important?

Thanks.

few more inputs..

1)My Machine info ASUS N56VJ

2)output for cat /proc/acpi/wakeup

So i guess suspending it from the closing of lid/using the settings menu,something erratic happens that makes the system not suspend any more.

My current OS: ubuntu 13.04 BETA 3.8.0-15-generic. though i tested with 12.10 as well and the observations are identical.

Any help please?

thanks for the reply.. but i cant test it as of now.. as my notebook has been bricked!.. will test it when it comes to life. :) –  ashishsony Apr 26 '13 at 11:33

I have an Asus n56vz, quite similar to yours, and the answer Helmo gave worked for me. I actually used the code from workaround #27 in the thread he provided:

Add SUSPEND_MODULES="alx" to /etc/pm/config.d/modules

Now suspend seems to work each time, regardless of how I suspend, pressing the power button, going through the menu, or the fn + f1 key.

Good luck!
