ASUS P5Q-EM DO 1-5
1.4 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.
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.
