Hello. I think I may have a problem with the CPU, but I was hoping someone could look at what I have done here and confirm so I don't waste more time on this one.
Original Problem:
No Power.
Troubleshooting:
Thermal camera showed MOSFET PQZ1 getting really hot and inductor PLZ01 was reading short on both sides.
Replaced PQZ1 with new B03N03R MOSFET.
Laptop now charges and powers on, but only for about 10 seconds before it shuts down abruptly. The fan also runs high during the few moments the laptop is on.
Removed PLZ01 and measured both sides of the inductor. The side leading to the CPU reads short while the side leading to the MOSFET does not.
Partially shorted CPU or something?
Attached schematic and a picture of what I am measuring with PLZ01 removed.
