How easy is it to replace a motherboard in a notebook?

[StoneAge]

Thanks for all the replies- I think I am just going to get a replacement and try to get a little money by selling it as a parts computer.

One of the deciding factors was finding www.zd7000forums.com on which I found out a LOT of people had recurring motherboard failure problems- so it looks like this has a high probability to be a big hole to throw time/money into.

Another question- if I sell this is there any way to reformat the hard drive (when the computer starts up there is no image on the monitor) so no personal info can be taken from it- or should I just remove it?
