=== 1. ''Possible reason: Power supply failure'' ===
=== Solution - Check power supply (PSU) ===
*Make sure the LED on the power brick is lit.
*Make sure the DC cable is not damaged and connected properly to the machine.
*Make sure the AC cord is properly plugged to both sides (Wall mounted well plugged).
*Try to plug the DC cable to the alternative DC socket on the Airtop3.
=== 2. ''Possible reason: Memory failure'' ===
=== Solution - Check memory (RAM) ===
*Verify diagnostic LED (R) lit <span style="background:Green">Green</span>*.
*If lit in <span style="background:yellow">Yellow</span> it means memory initialization has failed.
*Verify RAM modules seated correctly and firmly in their respective sockets.
*Try to eliminate faulty memory sticks by swapping them with one another.

=== 3. ''Possible reason: Peripherals failure'' ===
=== Solution - Check Peripherals (HDD/SSD/USB)===
*Unplug peripherals and try to power up with bare minimum, that includes HDD/SSD/USB devices.
*Verify power up without storage. Sometimes damaged drives may cause the overall system to malfunction.
=== 4. ''Airtop3 BIOS reset''===

'''LED-B (BIOS)*'''
This LED is <span style="background:yellow">Yellow</span> after display initialization.
If BIOS setup menu is needed, the DEL button is functional from the moment the B-LED is <span style="background:yellow">Yellow</span>.
The B-LED is <span style="background:Green">Green</span> when the OS takes charge of the system.
