DELL Latitude 7410 Powering Only When Connected to Mains

This symptom occurs when the laptop fails to initialize or maintain operation upon battery power alone. To confirm this, disconnect the AC adapter while the device is powered on; if the system experiences an immediate hard shutdown, the laptop is failing to draw power from the internal battery. Check for power LED indicators, such as a blinking amber light, which signify a mismatch between expected power input and actual system state.
