As an update - fiddling with BIOS and holding power button for 2-3 seconds seems to wake up the machine now!
(Again, this is an i7-4550u with HD5000 GPU) What works: - Waking up! What doesn't quite work: - Lid opening still doesn't wake - HD5000 driver is spewing errors on sleep/wake, so waking from within X will show console errors before rendering the screen properly.
