Seems that HP has made those keys active simply by pressing and holding them down (nowhere does it state how long that interval is).
BUT (and now comes the good news), they can be disabled in BIOS so that they function strictly as "F" keys (page 38):
"An action key performs an assigned function. The icon on each of the f1 through f4 keys and f6
through f12 keys illustrates the assigned function for that key.
To use an action key function, press and hold the key.
The action key feature is enabled at the factory. You can disable this feature in Setup Utility (BIOS).
See Using Setup Utility (BIOS) and System Diagnostics on page 68 for instructions on opening
Setup Utility (BIOS), and then follow the instructions at the bottom of the screen."
Then, after it's disabled in BIOS, they will only function as "special" keys as Mr. Clement stated, pressing the Fn key in combination with it:
"To activate the assigned function after disabling the action key feature, you must press the fn key in
combination with the appropriate action key."
Here's a link to the User Manual for further reference:

If you're still having a problem with it because of the proximity of the Fn key, then I believe you can disable it altogether by stopping HP Quick Launch in Task Manager. Test it out offline before gaming to make sure stopping it doesn't affect other keyboard functions that you may need.
Game on, my friend!!
