1. A point of sale system comprising:
a head unit configured to enter a sleep mode after a period of inactivity;
an input output (I/O) unit coupled to the head unit and coupled to a network, wherein the I/O unit is adapted to receive a Wake-on-LAN (WOL) event over the network, the WOL event comprising a network message;
the I/O unit comprising a Local Area Network (LAN) chip that is adapted to, in response to a received WOL event, generate a WOL event signal to a first embedded controller, the first embedded controller adapted to, in response to the WOL event signal, generate a wake up message and transmit the wake up message to the head unit, wherein the WOL event signal is adapted to cause a processor to wake up when the LAN chip is directly electrically coupled to the processor and the wake up message is different than the WOL event signal;
the head unit comprising a second embedded controller and the processor, the second embedded controller adapted to receive the wake up message and, in response, generate the WOL event signal to the second embedded controller directly electrically coupled to the processor, the WOL event signal causing the processor to exit the sleep mode, wherein the head unit is remote from the I/O unit.
