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

f1 Opens Help and Support, which provides tutorials, information about your Windows

Help and Support also provides automated troubleshooting tools and access to
customer support.
f2 Decreases the screen brightness level incrementally as long as you hold down the
key.

VGA video standard. This action key can also alternate images among other devices

turn off the keyboard backlight.
