|Do you have the wired network adapter working? if so connect a cable to the router so you can connect to the Internet. Go to the Sony driver site and look for the drivers for your system.|
Batteries have a life expectancy of 1-3 years before they get so weak that they do not charge. You need to replace the battery and there are many links online for that. There is a possibility that the charge section on the motherboard has failed and that is why it will not charge. Unfortunately very few shops have a battery for testing (I get users looking to see if I can try a battery but we do no stock them).
