3.2.1 No power
ASUS motherboards come with a standby
power LED. The LED lights up to indicate
that the system is ON. If the LED stays
unlit, follow the instructions below to fix
the problem.
1. Make sure to adjust your power
supply to the correct AC input
voltage in your area, and the power
supply is turned on.

“—”: On; “O”: Off
• Before adjusting the AC
input voltage, ensure to
disconnect the power
plug. Failure to do so will
seriously damage the
power supply unit.
• Failure to adjust the power
supply to the correct AC
input voltage will seriously
damage the system.
2. Make sure you have attached the
power cord to the wall outlet.
• Connect the power plug
directly to the wall outlet. DO
NOT connect it to the power
extension, uninterruptible
power supply (UPS) or other
devices.
• Exchange the power plugs of
the system and the monitor to
check whether the wall outlet is
working normally.
3. If the problem persists, you may need to contact your retailer for a new
power supply unit. If the power supply unit functions, contact your ASUS
motherboard retailer for motherboard warranty service.
