and so on with other keys g =gt and keep pressing it is ttttttttttttt
if i press h = hy and if i keep pressing it is yyyyyy
i have remove the keybord and i manualy short the pins on motherboard to see if the problem is in my keyboard… the problem is not my keyboard, it o the same thinks
so i wondering if the problem is the bios… or the motheroard he send me is no good.
the bios version is 7wcn38ww
mtm is invalid
lenovo sn is invalid
uuid number is there.
