i see, my mistake. on the notebook is writen only x55v, but on the box is writen x55vd - sx003. so X55VD
Thanky You very very much! (somewhat ate my PM away so I post this in public..) I will try the BIOS mod right away! But please tell me which tool did You use, as I tried both AMI and after that the Award tool, but both of them reported wrong input bios type... Should I do anything in advance of flashing the BIOS? Best Regards J4ni
