Grounding and PCB considerations

P+ and P-: These are the dual-purpose terminals used for both the Power Load and the Charger Input. Verified cause: Standby transformer T2 (EE13 core) has

Failure 4: Intermittent 5VSB

• Verified cause: Standby transformer T2 (EE13 core) has poor solder joints on pins 1 and 4. The schematic clearly shows T2 pin 1 going to D21 (SB340) and pin 4 to C31 (1000µF/10V). Reflow both.
