dúvida Lenovo G40-80 - ACLU3 / ACLU4 UMA MN-A362 Rev 1.0 - does not turn on, but if the led states on and does not consume

[Edwar estiven peña gaviria]

I have a levono g40-80, which does not turn on, shows that the power led and battery are working, but the equipment itself does nothing, I have a laboratory source and the source tells me in the amperage that it is consuming 0.012 A without the battery, with battery are 1.038A and the 20v are maintained, estor a little blind since I do not have the schematic,  if anyone is so kind to help me i would appreciate it very much.

@Edwar estiven peña gaviria 

does it have input voltage of 19v after input mosfets?

if yes, do you have the voltages of 3.3v and 5v on the coils?

[Edwar estiven peña gaviria]

in the case of the 19v if depsues of the mosfet if in the piece that has the numbering Pr301 I have the 19V (both before and after the mosfet), and in the case of the 3.3 and 5v if I also have them

@Edwar estiven peña gaviria I don't understand you have 3.3v and 5v?

[Edwar estiven peña gaviria]

What I mean is that the signals you mentioned I have both 3.3V and 5V, I apologize if I do not explain myself well

@Edwar estiven peña gaviria power button has 3.3v? zero when pressed?
super io has 3.3v in what represents the power and this pin resets when the power is pressed?

[Edwar estiven peña gaviria]

1: Power button, if you have 3.2V
2: The power button if it goes to 0V
Note that I hope is useful: In some touches (not all) that I do to the power button does not go down to 0v but goes down from 3.2v to 1.25v and returns to 3.2

Pin 33 of the Super IO marks 5.0v
Pin 75 marks 3.3V
Pin 100 3.3V
Pin 105 marks 0.0v
pin 110 cuandro preciono the power button pass from 3.3v to 0 and to 3.3v again

I write all this since I do not have the schematic, so these measurements are what I know in a way General, and I do not know if the data are explicitly what you are requesting.

and I thank you for the help

I'm really sorry if I don't answer you right away and I will recover (hospital) more or less, but I'm already close to the plate, I already try the pins you mention

[Edwar estiven peña gaviria]

I get this when I try to enter the download, it's because I have no credits, right?

@Edwar estiven peña gaviria mesmo sem esquema dá pra verificar pelo menos o básico. Comece rastreando os sinais mostrados no fluxograma do post #9. Verifique no SIO pois todos os sinais estão relacionados a ele.

 

Aguardo retorno. Grato.

Espero comentarios. Agradecido.
