+The functionality of WoL is dependent on three components supporting it:
   * **BIOS**: The system's BIOS must support WoL (you may have to enable WoL within your system's [[:install_batocera#bios_settings_if_batocera_fails_to_boot|BIOS settings]]).
   * **NIC**: The system's network adapter must support WoL to stay "awake" while the system is powered off.
+  * **OS**: The OS needs to be capable to tell the according NIC to go to sleep when it shuts down. Since Batocera is based on Linux, it got you covered.
 WoL is designed for use with wired Ethernet connections, but there are wireless NICs which may support Wake-on-Wireless (WoW). This article assumes you are using a standard wired connection.

 ==== Machine will not wake up anymore ====
-If you were successfully using WoL but suddenly it does not work anymore, a power outage of your Batocera system could be the issue. Since WoL functionality relies on a "sleeping" NIC state issued when shutting down the system, the NIC will not be in "sleeping" state anymore after power outage. Therefore you can only make WoL work again by manually booting and then shutdown the system once.
