I have taken the computer apart and have the motherboard at hand.
If I can find the current MB number how can I search for MB's replacement that are compatable with what I have and where might I find such items (IE how and what do I search for)

Go to ebay or use your laptop model number with your favorite search engine. Used laptop boards aren't cheap; it may be just as cost effective to get a new laptop and use your old hardrive. A good tech can migrate your old programs over to a new drive. Be sure it's the board and not the power supply before investing in used parts.
