Hi, for my sons laptop i bought new backlit keyboard MSI steel series. The backlit doesn't work, so I updated BIOS to latest version from Medion web site. Now the backlit stil doesn't work and the hot buttons (ventilator,P1,P2, backlit etc..) stopped working. The main problem is that i didn't made a copy of the previos Bios. Old bios was E1763IM7.50P / 1763EM7X(there is a blick on the picture of the last number) ver7.14. Any one can help? Medion Erazer X7831 MSN: 30018095 MD99032
