Hi wadyta,
Thank you for visiting Sony Community!
Sony Vaio VPCSB18GG is an Asia-Pacific model. Unfortunately, we have limited information about the part number and we do not have the compatible parts for this unit. You may contact Asia-Pacific support for further assistance.
For other concern and further assistance, we kindly recommend visiting our Sony Global Website for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.
