This problem appears again in XPS 13 9343 (sputnik 2015 edition), on stock Ubuntu 15.04:
Linux laminato 3.19.0-16-generic #16-Ubuntu SMP Thu Apr 30 16:09:58 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux I'm using EFI boot -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1161962 Title: XPS 13 wakes up from suspend spontaneously Status in Dell Sputnik: In Progress Status in linux package in Ubuntu: Incomplete Bug description: My XPS 13 wakes up from suspend by itself. This is very annoying and potentially dangerous since it happens while the computer is its sleeve/bag. Can't tell from the pm-suspend and dmesg what causes the behavior so please let me know what logs you need to investigate it and I will provide them. Further note: It seems like the spontaneous wake up is happening around 40 minutes after suspend every time it occurs. However, the spontaneous wake up does not occur every time.
