If your computer is really sleeping(S3 sleep state) then so are all the programs that are running on it and they can't do anything. The only way a computer can wake itself up is with a timer.
Something like an Xbox one that can wake itself is still running a subsystem to perform recognition, and I believe is still using power too, but hopefully less than it would during normal operation.
Also, if you are having trouble expressing yourself in English, please feel free to write in any language and we can use a translation tool to read it.
Salut James,
Vraiment merci beaucoup pour ton aide et désolé pour mon anglais!!!
j'essaie de m'exprimer en anglais pour que tout le monde puisse m'aider.
