Visual inspection: burns, cracked components, bulging capacitors, solder bridges.

Inspect the schematic page for the Charger circuit. Verify if the ACOK (Adapter Current OK) signal is being sent from the charging IC to the SIO chip. If ACOK is low, the system will reject the charger. 5. How to Use the Schematic with a Boardview File
