I rely on TinyPilot to manage a Windows PC that lives in a closet. TinyPilot is a Raspberry Pi-based KVM: it streams HDMI video from the PC and pretends to be a USB keyboard and mouse so I can type over the network. My PC also sleeps aggressively to save power. A real keyboard wakes it. TinyPilot did not, so every remote session began with a trip to the closet. Wake-on-LAN was unreliable on that motherboard, so I decided to make TinyPilot behave like a normal USB keyboard during suspend.
