procedures are discussed in the following sections.

Initiating Sleep (fn+f3)
Press fn+f3 to initiate Sleep.
When Sleep is initiated, your information is stored in random access memory (RAM), the screen is
cleared, and power is conserved. While the computer is in the Sleep state, the power light blinks.
CAUTION To reduce the risk of information loss, save your work before initiating Sleep.
The computer must be on before you initiate 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 RAM is saved to the hard drive. The factory
setting for critical battery action is Hibernate, but this setting can be changed in advanced power
settings.
To exit Sleep, briefly press the power button.
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.
ENWW Hotkeys 5

Switch the screen image (fn+f4)
Press fn+f4 to switch the screen image among display devices connected to the system. For example,
if a monitor is connected to the computer, each time you press fn+f4 the image switches among the
computer display, the monitor display, and a 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 receiving video information
from the computer.
The following video transmission types, with examples of devices that use them, are supported by
the fn+f4 hotkey:
●LCD (computer display)
●External VGA (most external monitors)
●S-Video (televisions, camcorders, VCRs, and video capture cards with S-Video-in jacks, on select
models)
●Composite video (televisions, camcorders, VCRs, and video capture cards with composite-video-
in jacks)
NOTE S-Video and composite video devices can be connected to the system only by using
an optional docking device.
Viewing battery pack charge information (fn+f8)
Press fn+f8 to display charge information for all installed battery packs. The display indicates which
battery packs are charging and reports the amount of charge remaining in each battery pack.
Decrease screen brightness (fn+f9)
Press fn+f9 to decrease screen brightness. Hold down the hotkey to decrease the brightness level
incrementally.
Increase screen brightness (fn+f10)
Press fn+f10 to increase screen brightness. Hold down the hotkey to increase the brightness level
incrementally.
