@Markerrag -- It isn't as bad as all that. You can find most manuals on the Internet for free so long as you have the model number of your computer. Just fire up your favorite search engine, run your query and that is usually all it takes.
And here is something else. Even if you are not sure how to do something such as replace a wireless card for a laptop (or module, as the case may be) you can probably find step-by-step instructions for that, too.
And all of that is available for free. Pretty cool, huh?
