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)
- 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
