Hallo all.
I have a sony vaio pcg-313111m with mbx-244 TUCANA m/b. The laptop has no power.
When I first open it I see that the U51 rt8223 was burn. I replace it and when I plug the power supply I have 10mA but still no power. I do some measurements: U51 pin16: 0.5V, U67 pin28: 19.28V, pin4: 19,28V, U65 pin1-4:19.25V, pin5-8: 0.7V.
I don't know where to look, if someone can help I will be grateful.
The schematic
Thanks in advance.
