I understand that you are having an issue with the notebook not starting, and wanted to assist you!  I see that the Caps Lock and Num Lock will blink 3 times, before the notebook restarts.

The blink code that you provided, usually indicates an issue with the Memory Modules.  Try reseating the Memory Modules, and let me know the results.
