Same question, different Vaio. I got a PCG-K25. What could I do to keep this thing running with the new sony vaio. It has 512mb of memory, and like 60gb of hard drive. Would it be worth it to replace the internal hard drive, or just buy a external one? Also she told me the fan might not be working, how can I tell? It's blowing the warm air out the back. Would it be worth the money to get a cooling pad?
