Since modesetting may play a part in making resume fail, I retried after switching the onboard Intel Q35 graphics of the HP dc7800p CMT to an Nvidia GT520.
Expectedly this has caused some changes to how the system behaves:
It will suspend once, stopping its fans - as well as usually respond to the keyboard Wake Up button and even work long enough to allow the user to re-logon, but then often freeze or panic with the Caps Lock and Scroll Lock lights blinking.
If it does continue to a usable desktop, further use of the Sleep key will only cause the monitor to go dark briefly, but always keep the fans running, and automatically wake up again just seconds later most of the time - also resulting in freezes with Caps Lock and Scroll lock blinking in many cases.
No chance at using Ctrl-Alt-F1/7 to recover from there of course.
