I read the "my situation is this ..."
Put the laptop in the closet with lid open, install the WOL.service, ssh to the laptop and sudo poweroff. laptop is off. From the other room you work on, send a packet to the mac address, the laptop should wake up and be pingable. Send again sudo poweroff, the laptop turns off and not be pingable. Then send the packet again, laptop wakes up and is pingable. This is option 2.
