Does anyone have boardview and schematics for Dell Precision 3480 laptop?
Computer shows no signs of activity: 5V 0A is showing when the charger is plugged in. No means to test whether computer runs off the battery since the battery is currently dead.
No heat spots of any kind with the charger plugged in. No shorts that I can see. Both USB-C ports appear to be in great condition. TPS65994bf chip gets 5V but not switching on 20V.
Before I attempt to change the chip, perhaps other areas I can look in?
