HP LAPTOP PAVILION 15 NOT CHARGING Repair

Charging Port (DC Power Jack)

The DC power jack, often subjected to physical stress from plugging and unplugging, can develop internal breaks or loose connections. This prevents the necessary voltage from reliably reaching the laptop's internal charging circuitry, resulting in no charging indicator LED and an inability to power on or charge the battery. The initial intermittent operation and subsequent complete failure are consistent with a degrading connection, as observed in similar cases where users reported needing to 'push hard' on the charger.

Motherboard (Charging Circuit)

Even if the external power adapter and charging port are functional and delivering voltage to the motherboard, a fault within the motherboard's integrated power input or charging control circuit can prevent the system from recognizing the incoming power, activating the charging LED, or distributing power to the rest of the system. This could be due to a shorted component on the board, as indicated in troubleshooting scenarios where 19V reaches the DC-in jack but the charger LED remains off.

AC Power Adapter

A faulty AC power adapter fails to supply the correct voltage or current to the laptop. This prevents the laptop from receiving power to operate or charge its battery, leading to no charging indicator LED and no power-on response. While a common cause, similar troubleshooting instances suggest the issue persists even with a different adapter, making it less likely to be the sole cause in this specific scenario.
