I can't turn on the computer, it doesn't wake up

LED Diagnostics feature is available only for models configured the with FM-AT2 FACE module

1. 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 (power brick and to the wall).
  • Try to plug the DC cable to the alternative DC socket on the Airtop2.

2. Check memory (RAM)

  • Verify diagnostic LED (R) lit Green*.
  • If lit in Yellow 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.

*LED Diagnostics feature is available only for models configured the with FM-AT2 FACE module

3. 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. Airtop2 BIOS reset

  • Power down the PC and unplug the power cable.
  • Open the service door.
  • Remove the disks cartridge.
  • Reset the BIOS by pressing the low profile push button SW1 (RTC_RST).
  • 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 Yellow after display initialization.
   If BIOS setup menu is needed, the DEL button is functional from the moment the B-LED is Yellow.
   The B-LED is Green 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

I don't have any display output, there's nothing on the screen

1. Screen functionality and connectivity

  • Make sure both power and display cables are connected firmly on both sides.
  • Advise the H(Hdmi)/D(Display port) LEDS, Green means the cable is connected to the monitor properly.*
  • Make sure the screen is turned On and is functioning.
  • The best way to check screen functionality is by connecting to a good known working machine.

*LED Diagnostics feature is available only for models configured the with FM-AT2 FACE module

2. Validate memory

  • Display issues on POST are a common symptom of incorrectly assembled or bad Memory DIMMS
  • Please refer to Check memory RAM to diagnose Memory
