Looking for a bios update for a hp port replicator model PA287A(HSTNN-IX02) having problems when a hp 6510b laptop is docked were touchpad works irratically when it is docked only ,all sw and bios patches have been installed on laptop no drivers for the dock is found anywere on the net , thank you

There is no bios update for this item. What you might need to do is locate a firmware update for it if there is one. The issue is that something in the replicator is using the same IRQ that the touchpad has. Dock the computer and use device manager and see if there are any conflicts. If there are set up a hardware profile for docked and normal. In the docked mode you want to disable the other offending hardware.
