Sony Vaio PCG-71911M VPCEH2N1E schematic

[Raul Bob]

I have changed the power jack and laptop don't want to start no more. No leds power in no nothing. I need a schematic to find fuzes so i measure them to be shure it is OK. I measure power with multimeter and i have power on motherboard at power jack connector. Laptop worked ... When i tried to move it i forced jack and this broked. I find this only next day when my batery discarged. Charger gives me 18v . Can this be an issue?

Hi, you don't have any fuses in your laptop, your charger gives 18V DC, the correct voltage must be 19.5V DC. I do not know if 1.5V DC below the normal voltage will cause problems, it depends on the design of the charging circuit.
