Hi dk1350,
Welcome to Sony Community!
IRX4580XTD doesn'r sound right. Vaio computers usually starts with VPC,VGN,SVP,SVD,ect.
Here are the steps to check the model name of the computer.
- Click the Start button and then click All Programs.
- In the All Programs menu, click VAIO Care folder.
- Click VAIO Care.
- The model name is displayed along the bottom of the VAIO Care window. (e.g., VGN-FW550F)
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/.
