Onboard LED

The motherboard comes with a standby power LED that lights up to indicate

that the system is ON, in sleep mode, or in soft-off mode. This is a reminder

that you should shut down the system and unplug the power cable before

removing or plugging in any motherboard component. The illustration below

shows the location of the onboard LED.

Before you proceed

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

• Unplug the power cord from the wall socket before touching any

component.

• Use a grounded wrist strap or touch a safely grounded object or a metal

object, such as the power supply case, before handling components to

avoid damaging them due to static electricity

• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic

pad or in the bag that came with the component.

• Before you install or remove any component, ensure that the ATX power

supply is switched off or the power cord is detached from the power

supply. Failure to do so may cause severe damage to the motherboard,

peripherals, and/or components.
