Sleep & Hibernate on D525/Nvidioa GT218 ION

Sleep and Hibernate don't work as expected.


Sleep
=============

Does sleep but most times doesn't wake up. To wake up I press the power button. A blue led is turned on if wake up is successful. But most of the time the screen stays black and the blue led flickers just one second. Only a reboot (press power button 5 seconds) is possible.

Syslog shows:

Aug 20 13:14:09 sparky NetworkManager[632]: <info>  sleep requested (sleeping: no  enabled: yes)

Hibernate
===========

Most of the time hibernate turns screen black but doesn't turn off as expected. Power consumption is as high as in running state.


Sylog of failed hibernate:

How can I debug this problem?

Thanks for any help.

#1
Sleep
==============

I changed now the hardware from a silent Shuttle XS35GTV2 to a silent XS35V4. Sleep works now without any problem. I think it has to do with nvidia driver (black screen on wakeup). By the way XS35V4 is a brilliant hardware with a J1900 processor, completely silent and consumes only 6-12W! Full screen hd movie on youtube no problem.


Hibernate
==============

Still not working. I did some search on the internet but didn't find a final solution. It looks like hibernation depends on a swap partition? But my sparkylinux doesn't have any swap partition.

Does hibernation work for others?
