some laptops require the user to turn on the PS2 mouseport in the BIOS setup and possibly turn off the keyboard pointing device (touchpad or pointer button) so there is no conflict between cursor movements being directed by two different sources. Perhaps yours is like that?
I just got a Dell Inspiron 2200. Running on Win XP SP 2, with 512 RAM, and 30 GB. I'm trying to plug in my microsoft optical intellimouse but the laptop isnt picking it up at all, the light on the mouse isnt even on, so its getting no power? am i doing something absurdly wrong? the computer will not detect the mouse atall. thanks for the help.
