This happened to me a couple of times, maybe more. I doubt Intel Rapid Start is the problem. Also, I configured it to hibernate my laptop after 15 minutes and my laptop still managed to wake up from suspend within that amount of time.
I could investigate that much as it happens randomly and always in the wrong moment, but I've managed to grab the dmesg the last two times it happened. Unfortunately, I couldn't find anything interesting in there. It shouldn't be complicated to realize a workaround (if wake up while lid is closed => put to sleep again), but I still would like a proper fix and an explanation of this problem. ** Attachment added: "dmesg autowake 1" https://bugs.launchpad.net/dell-sputnik/+bug/1161962/+attachment/4241232/+files/dmesg_autowake1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1161962 Title: XPS 13 wakes up from suspend spontaneously To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1161962/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
