Hi JacoSwart,
Welcome to Sony Community!
We don't have ways to check the model using the serial number. If you still have the laptop with your, you may check the model by going to Vaio care, or BIOS page, or underneath the battery compartment (if the battery is removable).
We kindly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.
Regards,
Jen
