I had a similar issue when I installed Kubuntu 13.04 on my laptop, hibernate would behave as you mentioned... I fixed it by disabling my Bluetooth module. It would appear that on occasion Bluetooth, WLAN, and Ethernet drivers can interfere with hibernation.

Perhaps try disabling them systematically and see if your hibernation issue still occurs.

  • Thanks for your reply. Can you tell me in detail how to disable them before hibernating? do i need to do it everytime or the setup is onetime? pls advise.

Try this link How to enable hibernation?

In short do this:

  1. Type in the following at prompt (this example uses gedit as editor):

    gksudo gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

    If the file already exists, it might be a good idea to save a backup copy.

  2. Fill it with this:

    [Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

  3. Save the file and reboot.

It worked for me on HP-540 laptop without disabling anything
