Examining the scheme, as against the component in the notebook card has not printed since the position of the component Posted after 1 hour 51 minute 54 seconds: Notebook is not turning nor the led on the power button, despite having 19v and also the voltage present on the J5608 connector 3.3v, and when I press the power button, this voltage is 3.3v drops to 0 volts, which is normal. I do not see hot components in the circuit. None of the components on the board are identified by codes indicating their position on the schematic. Where do I begin to measure and test the components? |
