Hotkey Description
fn+escescDisplays information about system hardware components and the system BIOS
version number.
fn+f3Initiates Sleep, which stores your information in system memory. The screen clears,
and power is conserved. The power lights blink when the computer is in the Sleep
state.
To exit Sleep, briefly press the power button.
CAUTION:To reduce the risk of information loss, save your work before initiating
Sleep.
NOTE:If a critical battery level occurs while the computer is in the Sleep state, the
computer initiates Hibernation and the information stored in memory is saved to the
hard drive.
The function of the fn+f3 hotkey can be changed. For example, you can set the fn
+f3 hotkey to initiate Hibernation instead of Sleep.
NOTE:In all Windows operating system windows, references to the sleep button
apply to the fn+f3 hotkey.
fn+f4Switches 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+f8Displays charge information for all installed batteries. The display indicates which
batteries are charging and reports the amount of charge remaining in each battery.
