My few months old notebook G51Jx was repaired by Asus TSD. They replaced the mainboard and videocard. Now Windows was not genuine anymore. After recovery also. So Asus told me to use the productkey on the back of the notebook. That works, but I had to activate via internet. So it is not pre-activated anymore. I think there is no SLIC 2.1 in de bios. How do I get that back?
