: Use the boardview to safely locate the source, gate, and drain pads of the two primary DC-in MOSFETs. If the gates fail to receive their required turn-on bias voltage from the charging IC, the main power rail (+19V) will stay isolated, disabling the laptop entirely. 2.

A strange issue reported by a technician on ChinaFix. After swapping multiple motherboards, the only thing that worked was plugging in a (bad) battery first to "wake up" the circuit. The solution involved checking the RT8243AZQW chip (the main system power controller) which was overheating, causing the logic to fail until a battery forced a different power path. The boardview is vital to trace the 3.3V and 5V enable signals from this controller to the EC.
