== I can't turn on the computer, it doesn't wake up? ==
* Please use the [[Airtop2 LED behavior description]] for further diagnostics.
'''LED Diagnostics feature is available only for models configured the with FM-AT2 FACE module'''
===1. Check power supply (PSU)===
*Verify Make sure the LED on the power supply brick is lit.*Make sure the DC cable is not damaged and functions connected properlyto the machine.*If you have another power supply use it Make sure the AC cord is properly plugged to eliminate both sides (power brick and determine to the failing sidewall).*In case you use other power supply make sure it provides uninterrupted power and stable groundingTry to plug the DC cable to the alternative DC socket on the Airtop2.
===2. Check memory (RAM)===
*Verify RAM modules are installeddiagnostic LED (R) lit <span style="background:Green">Green</span>*. The system will not boot without *If lit in <span style="background:yellow">Yellow</span> itmeans memory initialization has failed.*Also Swapping DIMMS with a good known working ones could Verify RAM modules seated correctly and firmly in their respective sockets.*Try to eliminate faulty memory stick issuessticks by swapping them with one another.
'''LED-R (RAM)''' This LED turns <span style="background:green">Green</span>, the moment the memory initialization is successful. This LED is <span style="background:yellow">Yellow</span> while the memory initialization is in progress. If the memory initialization has failed, for example: There is no DIMM installed / the DIMM is not supported - the R LED will stay <span style="background:yellow">Yellow</span>. The R-LED should stay <span style="background:Green">Green</span> at normal operation, also after BIOS POST is over. '''*LED Diagnostics feature is available only for models configured the with FM-AT2 FACE module*'''
===3. Check Peripherals (HDD/SSD/USB)===
*Mount the disks cartridge and close the door.
*Plug the power and power up the PC (either auto-on or pressing power button).

'''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.
'''*LED Diagnostics feature is available only for models configured the with FM-AT2 FACE module*''' == Airtop2 with Linux starts up with flickering/bad display == * [[File:Airtop2-bios-reset.gifrunning on embedded GPU is flickering/bad display on Linux]]
== I don't have any display output, there's nothing on the screen? ==
===1.Screen functionalityand connectivity===* Make sure both power and display cables are connected firmly on both sides.* Advise the H(Hdmi)/D(Display port) LEDS, <span style="background:Green">Green</span> means the cable is connected to the monitor properly.** Make sure the screen is turned on On and works properlyis functioning.* The best way to check if plugging it screen functionality is by connecting to a good known working machine.
===2. Proper connectivity==='''* Check if LED Diagnostics feature is available only for models configured the HDMI/DP cable are well connected to both the PC and the monitorwith FM-AT2 FACE module'''
'''LED-H (HDMI port)''' This LED is <span style="background:Green">Green</span> only when the HDMI port of the internal graphics is connected to a monitor. '''LED-D (Display Port)''' This LED is <span style="background:Green">Green</span> only when one or both of the Display Ports of the internal graphics are connected to a monitor. '''*LED Diagnostics feature is available only for models configured the with FM-AT2 FACE module*''' ===32. Validate memory===
*Display issues on POST are a common symptom of incorrectly assembled or bad Memory DIMMS
