$sudo nano /etc/systemd/logind.conf

Uncomment 'HandlePowerKey=ignore', save and exit.

$sudo nano /etc/acpi/powerbtn.sh

Last line reads /sbin/shutdown -h now "Power button pressed"
Comment it out, and add new line

gnome-session-quit --power-off

Save and exit.

sudo restart systemd-logind

No response following the post,

$whereis gnome-session-quit
$sudo nano /etc/acpi/powerbtn.sh

fixed the line to read /usr/bin/gnome-session-quit --power-off
