Board-level diagnosis for power, charging, no-display, BIOS, port and component faults where practical repair may be possible.
Board-level diagnosis
Find the affected section before deciding the repair.
A motherboard fault may involve power input, charging, voltage regulation, BIOS, display output, ports or damaged components. Diagnosis is used to judge whether component-level repair is practical.
