How to identify LED Light codes:

When a laptop or computer first powers on, it goes through an initial set of diagnostic tests to make sure vital components are preforming correctly. 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.
  • Identify the correct flashing light sequence.
