NOTE: Depending on the country or region, your keyboard may have different keys and keyboard
functions than those discussed in this section.
Using the keys
You can quickly access information or perform functions by using certain keys and key combinations.
Using the action keys
An action key performs an assigned function. The icon on each of the function keys illustrates the
assigned function for that key.
To use an action key function, press and hold the key.
CAUTION: Use extreme care when making changes in Setup Utility (BIOS). Errors can prevent the
computer from operating properly.
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 52 for
instructions on opening Setup Utility (BIOS), and then follow the instructions at the bottom of the
screen.
After you have disabled the action key feature, you can still perform each function by pressing the fn
key in combination with the appropriate action key.
