How the Blue LED Works by System Conditions

Here is the information for how the blue Alive LED indicated by the system conditions.

  • No boot media + RAM: Solid light and the device booted to BIOS.
  • Boot media + No RAM: Solid light but shows nothing on the monitor.
  • No boot media + No RAM: Solid light but shows nothing on the monitor.
  • Boot media + RAM: Solid light and the device booted normally. If any OS is absent from the recognized boot drives, the device booted to BIOS.

So, the blue LED always turns on regardless of recognizing RAM modules.

But in this point, we can think that the indirectly way to know the RAM modules recognized or not.

Plug the power cord without boot media, if the RAM module works then H2 is going to boot to BIOS after about 10 seconds. If so, when you push the power button on the board, the board turns off immediately.
