Identifying the hot keys
A hot key is a combination of the fn key (2) and either the esc key (1), or one of the function keys (4).
To use a hot key:
▲
Briefly press the fn key, and then briefly press the second key of the hot key combination.
Hot key combination Description
fn+esc Displays system information.
fn+f3 Initiates Sleep, which saves your information in system memory. The display and other system
components turn off and power is conserved.
To exit Sleep, briefly press the power button.
CAUTION: To reduce the risk of information loss, save your work before initiating Sleep.
fn+f4 Switches the screen image among display devices connected to the system. For example, if a
monitor is connected to the computer, fn+f4 alternates the screen image from computer display to
monitor display to simultaneous display on both the computer and the monitor.
Most external monitors receive video information on the computer using the external VGA video
standard. The fn+f4 hotkey can also alternate images among other devices that are receiving video
information on the computer.
fn+f6 Decreases speaker volume.
fn+f7 Increases speaker volume.
fn+f8 Launches HP Power Assistant. Displays charge information for all installed batteries. The display
indicates which batteries are charging and reports the amount of charge remaining in each battery.
