HP Notebook PCs - Some Function Keys or Keyboard Shortcuts Do Not Work Correctly with Windows 7
Special function keys trigger the desired action twice
When using the special function keys in Windows 7 the corresponding action may be triggered twice. For example, when pressing the Fn+F6 keys to toggle the mute on the computer, the sound will mute and then unmute. Or when pressing the FN+F3 keys to launch the default Internet browser, two browser windows will open.
