I have just received my corporate Lifebook S7220, with docking station (or port replicator) which has a PS/2 port on it. I plug into the PS/2 port a splitter (Y-cable) with my Fujitsu-Siemens keyboard and Fujitsu-Siemens mouse (Logitech M-SBF69) on it. All works fine except for the scroll wheel. The scroll wheel switch works OK but not the scrolling action. The Synaptic touchpad, which shows as a PS/2 connected device, is disabled when the PS/2 mouse is attached - there is a BIOS setting for this which corporate policy does not allow me to change (?).
I'm running the latest patched version of Windows XP. Logitech says there is no need for a driver. The mouse never shows up in Devices - only the Synaptic touchpad is visible.
Why don't I just use a USB mouse? Well, I have a PS/2 KVM switch, and it would be nice to continue to use it.
I think that this is a BIOS issue. Any suggestions?
