I can confirm that suspend works properly with Bios 1.15.4 but it's again broken with 1.17.3 :(

Latitude E5470] suspend/resume failure Status in linux package in Ubuntu: Confirmed Bug description: To generate the crash: 1) Suspend the system (e.g. choose suspend from the top menu). 2) At any point, unplug the cord (the bug happens if I unplug at any point after suspend, even if I then replug before I resume) 3) Try to resume (pressing power button). Computer reboots. What should happen: Regular resume from suspend. (If I leave the computer plugged in, resume works fine.) I have performed the tests at https://wiki.ubuntu.com/DebuggingKernelSuspend and included the results. Note that the computer never crashes during any of the tests except when /sys/power/pm_test is 'none'. This appears the same/similar to #bug #1645758 but I dont't know how to add to the apport info to that bug instead of filing my own.
