We're sorry to hear that you are having a hard time looking for this driver. What has changed prior to the issue? Have you already checked the Sony Website?
This is what we have on the website that is compatible for your laptop (Windows 7 64 bit), Intel® Chipset Driver, this utility installs the originally shipped version of the Intel Chipset Driver. I hope this helps.
