BTW, this is not as it is supposed to work, is it? When the lid is open, and 
the system suspends/hibernates, the lid sends a wakeup signal as soon as the 
system has gone to sleep mode. This seems an odd behaviour. Perhaps it is the 
laptop firmware that misbehaves.

In any case, as a workaround I've put the following script in /lib/systemd/
system-sleep/

#!/bin/sh
#
# /lib/systemd/system-sleep/lid_wakeup_disable 
#
# Avoids that system wakes up immediately after suspend or hibernate
# with lid open (e.g. suspend/hibernate through KDE menu entry)
