I want to attach an external mouse and keyboard to an old laptop (Compaq Armada 4110d). The laptop has a ps/2 connector at the back (marked KB and Mouse). The laptop works with an external keyboard or mouse individually, but when I try to use one of those convenient Y-connectors (also with individually marked connectors for KB and Mouse), the external keyboard refuses to work. When I connect JUST the keyboard to its proper connector at the cable (and leave the mouse unconnected) the keyboard doesn't work either. I'm pretty sure the splitter/cable is still OK and not damaged since it was purchased and used only about a month ago for use on another-brand laptop. Is there another kind of splitter that I should be using for this Compaq laptop? I used the splitter/adapter on Thinkpad with no problems whatsoever. The laptop is roughly 10 years old. Currently with W98se. The laptop manual doesn't give any clue whether using external mouse/keyboard simultaneously would NOT work - except to show that the clock and data pinouts for mouse and keyboard use are exactly the same. So... would this mean that any splitter WON'T work?
