Suggestion:
If you get really desperate, go on ebay and find people selling your laptop. Then, send them msgs asking if they will mail you a copy of the software for you for a nominal fee.
Another thing is, if you can find out what mfr and model they used for components in your laptop, maybe you can get the drivers from the actual mfr's websites?
A little extra:
From someone who's tried looking up drivers for a sony product, Sony's support website is terrible.
