Using keypad w/laptop, beep sounds

I just bought USB number keypad to use with a laptop or notebook computer. Yesterday, I connected it to a Gateway laptop (Win XP) that I occasionally use at a client's office. It was immediately recognized; I used it and was pleased with the experience.

I later tried using with an older Compaq Presario 700 laptop. Prior to connecting it, I had turned on the ToggleKeys setting that makes the computer beep when pressing the Caps Lock, Scroll Lock, or Num Lock keys. It's an audible signal that's helpful in knowing whether the Lock key is being turned On or Off; for example, it you hit the Caps Lock key to turn it on, you hear a high pitched beep; turning it off yields a low pitched beep.

On the Compaq Presario (Win XP), I had to disable the Use ToggleKeys setting; otherwise, hitting any key on the keyboard caused a beep. Now that I think about the Gateway, I believe ToggleKeys setting was disabled on it; I had not enabled it because the computer does not belong to me. But, the point is, I would think the ToggleKeys setting could be enabled and, of course, hitting number keys on the keypad would not cause beeps.

As I test, I connected the keypad to my desktop PC (Win XP). With it, I CAN have ToggleKeys enabled while using the keypad and NOT get beeps when hitting the number keys on the keypad. Surely, this is how it should work.

I suspect that nothing can be done to correct this with the Compaq Presario, but thought I'd post the explanation here in case anyone has any thoughts on whether some Windows or BIOS setting can be changed in the Compaq Presario so that the keypad works properly with ToggleKeys enabled.
