Since the wakeups are random and doing tests is complicated, I'd like to ask to all of you with this problem to try the following.
First, run the following command: cat /proc/acpi/wakeup Look at all the devices that are able to wakeup the laptop (those with *enabled) and for each of those (except for LID0), do the following: sudo echo DEVICENAME > /proc/acpi/wakeup e.g. sudo echo EHC1 > /proc/acpi/wakeup Check with the first command if all the devices are *disabled (except for LID0 of course). Note: these changes are not permament. -- 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.
