Check the pwbtn RSMRST and DNSBWON on the I/O if it's available when you power on .

 

[Usr0104]

Excuse my ignorance, where can I see that?

 

[admin]

It8987e it's the I/O Do a search for its datasheet than found rmrst and other signals if they are available when you power on your lap .

 

[Usr0104]

It8987e es la E/S Haga una búsqueda de su hoja de datos que encontró rmrst y otras señales si están disponibles cuando enciende su regazo.
