HP notebook pc's require several drivers depending on what hardware was installed in them. As you probably realize, HP posts nothing other than a touchpad driver for this notebook. Notebooks (unlike desktops) require specific drivers from the laptop maker. You may be able to order a cd-rom containing the required drivers. We do not know what hardware HP installed in your notebook so there's nothing more we can do for you other than to tell you to check the product information link on the webpage for this machine to see if you can figure out what hardware is onboard. There are a couple of software utilities (Everest and Belarc Advisor) that may also be able to id your machines hardware.
