...Did you ever disable it in the bios?
...If it is enabled there, it must be a windows setting. I have a Dell laptop in front of me and I can enable/disable in the control panel -> Mouse
Have you poked around in there?
Still having trouble with it disabled?
Have you disabled it in Device manager?
right click My Computer --> manage --> device manager --> Mice and Pointing devices right click on the one you want and enable/disable it.
I accessed the device manager through the control panel, but neither way gives me an option to control them. It only shows the "HID-compliant mouse" which I assume is my USB mouse.
when you put your new keyboard in, were there two connections or just one?
which model laptop is this?
I think that this is what you are already doing, but have a look here anyways. can you determine if you are using the Alps or Synaptics software?
