Using the action keys

An action key performs an assigned function. The icon on each of the f1 through f4 keys, and the 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 HP PC Hardware Diagnostics (UEFI) on page 63 for instructions on opening Setup Utility (BIOS), and then follow the instructions at the bottom of the screen.

To activate the assigned function after you have disabled the action key feature, you must press the fn key in combination with the appropriate action key.

CAUTION: Use extreme care when making changes in Setup Utility. Errors can prevent the computer from operating properly.
