My computer is a HP Z240 tower workstation, Ubuntu version:
Description: Ubuntu 18.04.5 LTS
Release: 18.04
I can and do suspend my computer by pressing Fn-Key + F1-key on the HP
keyboard. The F1 key is marked with a crescent moon to indicate this
functionality. The suspend state is indicated by a blinking led on the
computer case.
>From 16.04 I was used, that in suspend state any keypress on the
keyboard would wake up the computer again immediately: The screen would
(if turned on) display what was last visible when suspend was executed
through the abovementioned function key. The led on the computer case
would light steadily.
Now a keypress on the suspended computer leads to a short activation of
the harddisk, the led on the computer case will light steadily but the
monitor (also if on) remains dark. After about 2-5 seconds the harddisk
stands still again, the computer becomes silent and the led on the
computer case is blinking again, as in suspend mode. I presume the
computer is now again in suspend mode.
When this state is reached, a second keypress leads to a correct awake
from suspend, the harddisk spins, the led on the case lights steadily
and the monitor displays what is expected. The computer can then be used
as expected.
Note: I have 64 GByte of RAM and only 32GB Swap partition, so I presume
(and hope) that hibernation (RAM to Disk) plays no role here, only
suspend and wake-up from suspend.
