I'm new to Tom's and this is my first post. I have a Dell Insprion 8130 w/no touch pad settings window. I'm running Windows 7. In 'Control Panel' the 'Mouse' option indicates there is only a PS/2 compatible mouse option available. The 'Mouse" window on my Inspiron 1545 has a selection for a Dell Touchpad. I'd like to know what kind of touch pad I have, where I can download the driver that is compatible with Windows 7. Thanks
