Using the keyboard
Using the action keys
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)
and revert back to standard settings by pressing the fn key and an action key to activate the assigned
function. Refer to
Using Setup Utility (BIOS) on page 84 for instructions.
CAUTION: Use extreme care when making changes in Setup Utility. Errors can prevent the
computer from operating properly.
