Hi Christopher, I've updated the BIOS as suggested and it is now suspending when I close the lid.
I will however try this for a while as I have heard that the process of updating the BIOS resets something and it does then work for a while. Many thanks for your help either way, I will let you know how it goes. I ran the command again and it responded with: 13XK 03/28/2013 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027368 Title: [Samsung NP530U3B-A01UK] Laptop does not suspend on lid close To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1027368/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
