===== Sony =====
==== Battery Replacement Program ====
Sony initiated a global replacement program for certain lithium-ion notebook computer battery packs manufactured by the company to address the concerns of customers over the recent over-heating incidents in certain notebooks manufactured by companies other than Sony. We encourage all customers to check to see if their battery is affected and to follow the directions on proper use of their VAIO notebook and battery in Important Safety Information and Precautions. If you are eligible, a free battery will be provided to you.
The voluntary replacement program only applies to certain models and serial numbers of the VAIO battery packs. Select your battery model and part number from the drop-down boxes, type your serial number and then click the Check Battery button.
