: When you locate the schematic for the GS44B, GS54B, or NM-C561, ensure you understand the symbols and notation used. Schematics can vary slightly in representation, but they generally provide:
Essential standby voltages including +3VALW and +5VALW . These must be present even when the laptop is off for the power button to function. Primary Rails: +1.2V : DDR4 memory power. +1.05VALW : PCH/CPU standby power. gs44b gs54b nm-c561 schematic
