Hi yashwanth and welcome.

Have you reinstalled all the Sony Drivers and Utilities?

Unfortunately, you will have to update your Vaio manually. If you have changed from the original Sony OEM operating system, some things like Vaio Update and Vaio Recovery Centre will not work. You will also lose other applications and software.

You can download UPDATES from here: -

but you cannot download the original software.
