1.4 Before you proceed
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.
Onboard LED
The motherboard comes with a stand-by power LED. When lit, the green 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. The illustration below shows the location
of the onboard LED.
