Keyboard trouble

[Ferraz]

Hello there,

Im a recent intern in a shop where we repair computers and etc and I just recived a PC, an old laptop, ASUS L3000D and I cant fix it.

The problem is, the keyboard is working fine on BIOS but when I get in Windows it stops working..

It has now Windows 7 Pro, previous one, Windows XP (same problem)
Already tried lot of things and read hundreds of comments to solve this problem and nothing works, even my boss doesnt know how to fix it, so employee of the month goes for me if I can fix, i guess xDD

Tried:
-The energy thing, unplug all, pressing button till dischargers, plug back in, nothing.
-Tried all options in BIOS, nothing
-Modified Registers, nothing
-Unnistall Drivers, Install new ones, nothing
-Keyboard languages all set
-And many others things I cant remember now, it has been 3 days im working on this, my head hurts..

Its a PS/2 Standard Keyboard, directx recognizes it, its all fine there, I just dont know what to do more..
USB Keyboard works

Anyone can point me in the right direction?

Thanks in advance,
ps.: Sorry for bad English, Portuguese guy here

Its a laptop? Are these issues for the built-in keyboard? Does a USB keyboard work?
