Re: Diode and mosfet onboard testing


I test the motherboard with another power supply (work ok) and its led
flashing continuously
I exclude a problem to the power source, what is the next test you advice
me.

thanks so much

I have a fault on a laptop motherboard:
After I plug in the connector the power supply protection stop the power.

No component with visible fault (I control with a microscope), no
component
with heat surface.

My next step would be to test the power supply's protection
circuit.
Use a separate (controlable) load and see at what current the
supply kicks out.
