Problem
A laptop with no power or random shutdown can be caused by adapter fault, charging section issue, short circuit, liquid damage or motherboard component failure.
Diagnosis path
The correct path is adapter check, DC jack inspection, board-level visual inspection, short testing and data risk review before quoting.
Customer guidance
Motherboard repair should remain diagnosis-first. A starting range may be visible, but final cost depends on chip-level work, parts and warranty scope.
Diagnosis-first service: final estimate after inspection.
