Q: Has this system ever had any prior Ubuntu releases installed on it, or is Trusty the first?
A: This system has had Saucy installed on it but the installation to Trusty was fresh (drives wiped). The behavior described did not occur under Saucy

Q: Can you also see if this issue happens while the system is connected to AC power for 24 hours?
A: I have tested this with the system connected to AC and it does occur. 

Q: There are a couple of initial triaging steps we can perform. One
would be to test the latest mainline kernel to see if this bug is
already fixed upstream. If it is not, we should also find out if this is
a regression. If it is a regression, we can bisect to find the commit
that introduced this.

So in addition to testing this bug with AC power, can you also test the latest mainline kernel, which can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc5-utopic/

Just let me know if you have any issues or questions installing that
kernel.

A: Haven't done this but will over the weekend. I see the note regarding
the outdated bios and will also test that (upstream kernel first, see if
it recurs; upstream and stock kernel using new bios as well).

Q: Can you review your BIOS settings to see if there is an automatic
wakeup set there?

A: There is not.

Q: Also, is the system waking up 24 hours from the time it is suspended,
or does it wakeup at the same time of day? Just trying to see if an
external USB device is waking it at a specific time.

A: The system will wake up 24 hours from the time suspended regardless
of time of day.

Q: One last thing, the Firmware Test Suite can dump some CMOS data to
see if wakeup is set. If possible, can you install fwts and run the
following:

sudo fwts cmosdump

Then attach the output.

A: Done and attached

Title:
  [Dell XPS 15 9530] Wakes from sleep after exactly 24 hours + 3-5
  seconds

Status in Dell Sputnik:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Symptoms: The system will wake itself from sleep after very nearly exactly 24 hours, + / - 10 seconds or so. /var/log/pm-suspend.log will show this:
  Sat May 10 22:08:49 MDT 2014: performing suspend
  Sun May 11 22:08:54 MDT 2014: Awake.

  In this case the system has resumed after 24 hours and 5 seconds with
  no user request to do so. Steps to reproduce: Suspend machine by
  closing lid. The system can be plugged in to charge while it is
  suspended, and then subsequently unplugged, but the suspend occurs on
  battery power, and when the resume occurs the system is also not
  plugged in. I have not tested other permutations. No other action is
  necessary. The system will randomly resume 24 hours + 3-5 seconds
  later.
