Hi hazem madian, I would suggest you to contact Lojack and check if they can get records with the system service tag. For renewals also the same procedure can be followed and they will help you.
My laptop was stolen. I know that my ethernet modem is malfunction so there left two ways to log to the internet. First way was through WIFI and second through USB modem? So I need some one to confirm to me that the WIFI MAC address is the one that would appear during logging and not  the mac address. Also if the thief use his USB modem then what is the MAC address that would appear? Can I know if my stolen laptop has Lojack installed and enabled in BIOS? I used my service tag here, but I can't understand abreviations. Could any body tell me what is the abreviation of lojack for latitude e5420 in the laptop configuration?
what is Lojack abbreviation at latitude E5420 configuration?
