Take note of the following precautions before you install motherboard
components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. Use a grounded wrist strap or touch a safely grounded object or to
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
3. Hold components by the edges to avoid touching the ICs on them.
4. Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
5. 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.
Power LED
The motherboard has a green power LED (SB_PWR1). When lit, this LED
indicates that the system is ON, in sleep mode, or in soft-off mode, a
reminder that you should shut down the system and unplug the power
cable before removing or plugging in any motherboard component.
