These tests are called POST or Power On Self Test. When a test fails, the user is notified via POST codes, Light codes, or Beep codes. For diagnosing LED light codes you need to:- Power on the laptop or restart it if it is already on.

What about just one flashing LED? I have just the Volume Down light flashing. None of my LED’s are broken; they all light up during the startup check.
The volume down indicates a memory problem. possibly bad memory sticks or bad memory slots. Try replacing the memory.
I have the same issue. Did you find a solution?
