HP Compaq Presario C542EA Notebook PC - Manual (Page 26)

Switching 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 toggle images among other devices receiving video information
from the computer, such as S-Video.
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)
Initiating Hibernation (fn+f5)
Press fn+f5 to initiate Hibernation.
When Hibernation is initiated, your information is saved to a hibernation file on the hard drive and the
computer turns off.
CAUTION To reduce the risk of information loss, save your work before initiating Hibernation.
The computer must be on before you initiate Hibernation.
To exit Hibernation, briefly press the power button.
The function of the fn+f5 hotkey can be changed. For example, you can set the fn+f5 hotkey to initiate
Sleep instead of Hibernation.
