It's a 5 or 6 year old laptop with a 1.8 Ghz CD2 CPU, 1 GB of RAM (128 MB of which is going to the IGP) and 120GB HDD. It's just an old computer, I'm afraid. You can add another gigabyte of RAM. Which will help if you're running Vista or Win7. Also make sure you don't have any viruses or malware. You can also reduce the number of programs that start running upon booting the machine up.
I don't think Sony is going to be of any help. As the computer is obviously out of warranty. You may to see about bringing the computer to an independent computer repair shop. But 5 or 6 years a good run for a laptop overall.
