Hotkey combination	Description

fn+f1	Initiates Suspend, which saves your information in system memory. The display and other system
	components turn off and power is conserved.
	To exit Suspend, briefly press the power button.
	CAUTION: To reduce the risk of information loss, save your work before initiating Suspend.
	NOTE: If a critical battery level occurs while the computer is in the Suspend state, the computer
	initiates Hibernation and the information stored in memory is saved to the hard drive.
	The function of the fn+f1 hotkey can be changed. For example, you can set the fn+f1 hotkey to
	initiate Hibernation instead of Suspend.

fn+f2	Decreases the screen brightness level.

fn+f3	Increases the screen brightness level.

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 from the computer using the external VGA video
	standard. The fn+f4 hotkey can also alternate images among other devices that are receiving video
	information from the computer.

fn+f5	Initiates the QuickLock security feature. QuickLock protects your information by displaying the
	operating system Log On window. While the Log On window is displayed, the computer cannot be
	accessed until a user password or an administrator password is entered.
	NOTE: Before you can use QuickLock, you must set a user password or an administrator
	password.

fn+f6	Displays charge information for all installed batteries. The display indicates which batteries are
	charging and reports the amount of charge remaining in each battery.

fn+f7	Mutes or restores speaker sound.

fn+f8	Decreases speaker volume.

fn+f9	Increases speaker volume.

fn+f10	Plays the previous track of an audio CD or the previous section of a DVD or a BD.

fn+f11	Plays, pauses, or resumes an audio CD, a DVD, or a BD.

fn+f12	Plays the next track of an audio CD or the next section of a DVD or a BD.
