Hi

Just wanna clarify something. In BIOS, there is this option on the Mouse/Touchpad

I have selected PS/2 Mouse = Disable the integrated touchpad when an external PS/2 mouse is present.

What does this mean, I have connected my USB mouse and I can still use the touchpad. 

In windows, I need to install the driver and press Fn + F5 key to disable the touchpad. This should not be the case right as I have selected the PS/2 Mouse option in BIOS.

Please assist.
