My dell latitude d630 I have pressed and held down the "FN" key and powered the laptop on. Firstly, all three status lights on ones and then stay off. What does this error light sequence mean?

It sounds like you have a bad AC adapter . When you plug it in to the outlet in the wall and into your computer , do you see a charge indicator light on the computer? I'm asking you this because even with a bad battery your computer should operate without any problems with the AC adapter plugged in.

Testimonial: "Excellent purchased the new adapter and and what do you know problem solved.Thanks a million."

There are two common causes for this and both relate to the power supply.

First is that the connector on the main board is loose or has a bad connection

If you are proficient with a soldering iron this is an easy fix for approx $10

They have some very good step by step guides for replacing power sockets.

It could also be a dying power supply which is the second most common cause.

Replacements are easy to obtain and cost between $20 to $60.
If it is the PSU either get an original replacement (EBAY is best bet) or get one of the many multi laptop PSU's available but if you get the latter please make sure it carries enough or preferably MORE amperage than you need.

The old supply will have the details of both the voltage and current on it and you need to match the voltage exactly and keep the same or better current rating eg 1000 Mw or 1A or whatever it says.
