The "Dot" Key not working properly ----> .

Hello everyone,

in my ASUS, when I type the . <--- key (the dot one), instead of writin the normal dot . , it delete backwards (like the delete key, but in reverse).

Is the only key of the keyboard that is not working properly. Any advice?

I tried to do the shift, double shift and double shift + alt thing but is still not working.

Thank you in advance
