I continue with my Armada 3500 story and the keyboard problem

So if i'm right, the keyboard are plugged on the motherboard with a large
connector. But if i remove it, the continuous "beep" (like you run your
notebook and stay press a key all time) are still here.

Symptom now ...

Notebook run (after unplugged CMOS battery and the "press F1 to save
settings") but the continuous beep are here.. And the notebook boot but take
a very long time ... (3 minutes for passing bios, 10-15 minutes for booting
XP)

on the windows deskop, i can't use keyboard and mouse, even if i plug
external keyboard. But if i plug external usb mouse, i can move pointer but
not click on any icon.

I really need a solution for desactivate internal keyboard & mouse of my
armada 3500

Thanks for reading
