Thank you, the advice helped and now am able to use my touch pad. Cheers.

go to this HP site -- http://h18004.www1.hp.com/products/quickspecs/13569_na/13569_na.HTML

you will have to reboot, press F2 or F10 to enter the BIOS and disable the webcam from there. But read the specs first and see if there is a way to disable the camera by way of function key

If you have a wireless router and it is connected to the DSLor cable modem then - To connect to your wireless router, the router needsits wireless settings to be configured with the SSID, encryption key etc., alsothe wireless cards and wireless adapters in all the laptops/computers needs tobe configured with these router's wireless settings. Then the laptops/desktopcomputers can communicate with your wireless router and access the Internet via the DSLor cable modem.
If the other laptops are connecting to the wireless router, then look at the wireless card configuration in these laptops and apply the same settings to your HP Probook wireless card.

Double tap on the upper left corner of the trackpad.

You need to install the 'HP Hotkey Support'

Select your installed OS and search the HP Hotkey Support.
After that, download it and install it. Download.

Hi there,
Simply tap twice on the orange light and your pad will be working again, this is basically a lock like the HP had in earlier which was made enable/disable by Fn+F7 key, As a new advancement its a lock and also indicator, when you see orange light it means that touchpad is locked, for unlocking simply tap twice on the orange light on touchpad, and it will start working again
