In my case I had a new Dell 17 3793, updated BIOS, and installed Kubuntu 20.04 from a USB stick I created at the time 20.04 was released. If I don't give the install program access to the internet, then wake from suspend suspend works. But if I do give the install program access to the internet, or if I sudo apt update && sudo apt upgrade after install, then wake from suspend doesn't work. Using the original 20.04 kernel, 5.4.0-26 works but no later kernels I have tried work.

Further observations on failed wakeup: blank screen with flashing cursor. Caps Lock light does not change. But PrtScr+Ctrl+Alt+REISUB reboots. Ctrl+Alt+F2 or F3 etc and the cursor gives a barely observable flicker. Ctrl+Alt+F1 which should bring up the graphical login screen causes the flashing cursor to disappear, but still blank screen.
