I have this Sony laptop which does not switch on. Even the supply indicator on the front does not light up. i have opened the laptop. the supply is getting to the connector on the motherboard but i don't have any information to trace the voltages elsewhere on the motherboard. Can anyone help? May be a circuit diagram for the PSU part othe motherboard.
