Hello, <br>I just wanted to give you some news about it there is no need to answer<br>Now the computer still doesn't begin when the button is pushed but it starts without problems if it is unplug. Also I checked the motherboard or at least the top of it I didn't take it apart, I didn't see any leak. So I guess that can be a problem with the button itself, the battery inside the motherboard, or the motherboard itself. For now I will leave it like that because it starts without problems if I use the button in the back of the computer and later I will think about changing the motherboard.
<br>Thank you for all your answers<br>Megan<br>
