All the keys in the first row of my keyboard have stopped working, as well as the function keys. Can someone help me?

My computer is an Acer Aspire 5750 and the keyboard is ABNT2 (Brazilian Portuguese)

Thanks.

Você fala português? Bom, eu vou responder em português, se você não responder eu volto a usar inglês.
Funcionam as teclas: F1, F2, F4, F8 F12, Pause, Delete, Home, Pg Up, Pg Down e End, mas não funcionam todas as outras teclas F (F3, etc), nem o Esc e nem o Print Screen. Ah e também não funciona a tecla Fn, nem os comando provenientes dela

You speak Portuguese? Well, I will answer in Portuguese, if you do not answer I will use English again.

The keys work: F1, F2, F4, F8 F12, Pause, Delete, Home, Pg Up, Pg Down and End, but not all other F keys (F3, etc.), neither Esc nor Print Screen. Oh, and neither does the Fn key, nor the commands that come from it: anguished:

Yes, I speak Portuguese well. I suggest you create a new topic in the Portuguese community!
