Thanks for the reply. I understand the first two points, but I would like to ask you a little more on the third one, becouse I'm totally new to Flirc: what do you mean by "No button is recorded to the wake key in flirc"? If I would like to wake up the PC from S3 or S4 mode, using for example the "MENU" button of the Apple remote, I suppose I should record that button IR code (inside the Flirc configuration software) in order Flirc can wake up the PC when that IR code is listened, right? maybe the "No button" was intended for "That specific button"? sorry but is not clear to me
