Hi Kryptur,
The battery pack built in your VAIO computer is not removable that's why you can't find any replacement battery anywhere. We strongly suggest that you contact an authorized Sony service/support center and replace the battery pack with a new one specified by Sony.
We 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/ to assist you with this issue.
Regards,
Jen
