HP dv4-2160us manual Initiating Sleep, Initiating QuickLock, Decreasing screen brightness

Initiating Sleep

CAUTION: To reduce the risk of information loss, save your work before initiating Sleep.

Press fn+f5 to initiate Sleep.

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.

The function of the fn+f5 hotkey can be changed. For example, you can set the fn+f5 hotkey to initiate Hibernation instead of Sleep.

NOTE: In all Windows operating system windows, references to the sleep button apply to the fn+f5 hotkey.

Initiating QuickLock

Press fn+f6 to initiate 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 Windows user password or a Windows administrator password is entered.

NOTE: Before you can use QuickLock, you must set a Windows user password or a Windows administrator password. For instructions, refer to Help and Support.

To use QuickLock, press fn+f6 to display the Log On window and lock the computer. Then follow the instructions on the screen to enter your Windows user password or your Windows administrator password and access the computer.
