Hey everybody... I've got an HP Pavilion ze4400 on which the touchpad doesn't work. I can't be sure whether it's a faulty device or if drivers aren't installed. In Control Panel, under Mouse, Hardware, only one device (the USB mouse I'm using) shows up. I'm not sure what the standard touchpad driver for HP notebooks is. Going through the Add Hardware Wizard and telling XP that the device is already installed, it then gives me a list of installed hardware to select from. I don't know what that driver is, if it's even in there. Anyone know what the driver is? Anyone else have this problem? Thanks!
