Hit "FN" and the "NUM Lock" key together to unlock it.

I believe thats the combination.

Let me know.

The following website contains the needed drivers:

Select your model of CF-51 Toughbook, but you MUST be specific. There are about nine variations of the CF-51 so you must use the right drivers.

Download the hkeyapp, hkeyset, and hotkey files and unpack all files. Use the default unpack locations. If you download the files for a laptop version that is not your own, when you try to run any of these files the computer will tell you that the file is not for your model. If the files successfully unpack then you know you have the right files.

For hkeyset and hkeyapp you must run the set-up applications in the unpacked folders.

Go to Control Panel>System>Hardware>Device Manager and go to Other Devices.

The Hotkeys will appear as an "Unknown Devices" so if there is more than one, right click and choose "Update Driver".

Select "Install driver from specific location" and direct it to "C:\util2\drivers\hotkey" folder.

The computer will find the file and install the driver after which point you must restart the computer.

Hope this helps. It took me a while to figure this stuff out on my own so hope it speeds up somebody else's attempt.
