after i bought my sony vaio AR320E it works brilliatally.after sometime the bluetooth stops working and indicates that validity period expired.it is supported by toshiba.
I would guess that its not the hardware that need validating its actually the software, since Hardware doesn't need validating. I would suggest you try here http://support.vaio.sony.co.uk/submenu/selfservice.asp?site=voe_en_GB_cons I can't acttually search since you need to be registered to get proper information about different products and problems.
