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.

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.

  Running Xubuntu 12.10 with the following Sputnik Kernel: 
  3.5.0-26-generic #42+kamal15~DellXPS-Ubuntu
