Swap space and hibernation on Centos 7

[H <agents@xxxxxxxxxxxxxx>]

I just reinstalled Centos 7 on my Dell Inspiron 15 7570. This time I created a swap partitition that is 24 Gb in size since the machine has 16 Gb of memory. Still unable to hibernate with 'systemctl hibernate' which generates a message that a 'dependency on hibernate.target failed'.

Typing swapon -s or cat /proc/swaps I see:

/dev/dm-2 partititon 25161724 0 -1

free -m gives me:

...

Swap 24571 0 24571

What am I missing? Suggestions what to check are appreciated.
