[Help] Dell Inspiron 15 ac adapter wattage no determined

[Raziel19935]

Hello guys, I had repaired this laptop with motherboard Iris bsw mb 14279-1
https://ibb.co/RbDFh4G
But it does not detect the power supply, I changed the source, even the dumbest thing like charging the battery in another laptop and flashing the bios, Measure and have all your input voltages from the power supply .This is very rare

Any help are welcome

Post or link the schematic if on this forum. Outside links are not allowed.

Dell uses an adapter_id pin that functions with a single wire interface (Maxim / Dallas semiconductor) to offer the identity of the connected power adapter from Dell.

Be sure your adapter is the original and is suitable for this logic board. If it is, the circuit that starts at the dcin connector on the logic board needs to be reviewed.

This leg of the circuit does get damaged and there are a few threads on this forum discussing their repair.
