I had troubles with gaming with my new notebook G51Jx. The MB is G60J. The TSD has replaced the MB and Videocard. After recovery Windows is no longer genuine, because SLIC 2.1 is missing in the bios after the replacement. The pre-activation does not work anymore. For pre-activation is needed Asus's OEM digital certificate, Asus's home premium SLP product key, and SLIC 2.1 the your bios (which should be in the bios already). The Asus TSD said to use the productkey from the sticker on de back of the notebook. I want a bios with SLIC 2.1. What to do?
