Dell Studio 1735 LED POST Codes Diagnostic Indicators


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.

    I have a dell studio 1735 that will not boot. when I turn it on the lights will go from left to right, then back again, then the power shuts off. I have replaced hard drive, cpu so far with no improvement. Also, the only time the moniter works is when I push the “D” key, and start. My service tag is 3bwffg1, and my express service code is 7249942513. I have also replaced battery and charger. Any suggestions or help? Thx, Loren
