HP 8440P manual Switching the screen image, Viewing battery charge information

Page 47

When Sleep is initiated, your information is stored in system memory, the screen is cleared, and power is conserved. While the computer is in the Sleep state, the power lights blink.

The computer must be on before you can 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 memory is saved to the hard drive. The factory setting for critical battery action is Hibernate, but this setting can be changed using Power Options in Windows Control Panel.

To exit Sleep, briefly press the power button or press any key on the keyboard.

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.

Switching the screen image

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, pressing 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 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)

●DisplayPort

Viewing battery charge information

Press fn+f8 to display charge information for all installed batteries. The display indicates which batteries are charging and reports the amount of charge remaining in each battery.

Decreasing screen brightness

Press fn+f9 to decrease screen brightness. Hold down the hotkey to decrease the brightness level incrementally.

Increasing screen brightness

Press fn+f10 to increase screen brightness. Hold down the hotkey to increase the brightness level incrementally.

Activating the ambient light sensor

Press fn+f11 to activate and deactivate the ambient light sensor.
