Tool
Philips (cross) screw driver
The motherboard comes with an onboard standby power LED. This LED lights
up to indicate that the system is ON, in sleep mode or in soft-off mode, and not
powered OFF. Unplug the power cable from the power outlet and ensure that the
standby power LED is OFF before installing any system 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.
