Hello Guys
So i have this tablet and doesn´t power and not charching the battery.
i didn´t found any schematic for this board.
I though it was the charging ic BQ25601 i order a new one and i replace but didn´t solve the problem.
I have a ampmeter and i see that the resistance iscilate between 80ohms and 110ohms wich i believe is too much. with or without the battery is the same.
with ampmeter i check the consume and oscilate between 0.06a and 0.04a.
i tried to inject 5v in the usb port to check any short but isn´t and consume about 0.02a.
i check the battery connector and have no short, i check the board for short but till now didn´t find any.
sorry for the big text but if someone try to help knows what i already try.
thank you all in advance
