Hi kalle,
Welcome to Sony Community!
The SVS131A11T was not recognized by our system. To check for the correct model type "dxdiag" on the search box then hit the Enter key. A DirectX Diagnostic Tool windows will show up. Under System Information look for system model
Go to esupport.sony.com to get the compatible drivers and software of the laptop (US models).
Regards,
Jen
