Question about Dell Latitude D600 Notebook
basically the problem that you are having is a no P.O.S.T (power on self test ) issue or to make it clear the computer is having some problems turning on. Now, how is the capslock light related to the problem? For dell portables it uses Numlock, capslock and scroll lock key as diagnostic indicators as well. based on your discription, the off-flashing-off combination means that there is something wrong with the main board on your computer. and the badnews is the part costs a lot. you'd probably end up paying $400.00 for the parts and repair.
Hope this helps.

SOURCE: Dell D600 don't start
Try pressing firmly on the keyboard around the 6 and 7 keys and pressing the power button at the same time. Works with my D600 which has the same problem. Apparently it is a common problem with something looses or not soldered properly under there. Will eventually get around to pulling mine it apart to see if I can fix the problem permanently but this "fix" has been working for quite while now.
