HP EliteBook 8540w Mobile Workstation - Manual (Page 48)

Initiating Standby
Press fn+f3 to initiate Standby.
When Standby is initiated, your information is stored in memory, the screen is cleared, and power is
conserved. While the computer is in Standby, the power lights blink.
CAUTION: To reduce the risk of information loss, save your work before initiating Standby.
The computer must be on before you can initiate Standby.
NOTE: If a critical battery level occurs while the computer is in Standby, 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 in advanced power settings.
To exit Standby, 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 Standby.
NOTE: In all Windows operating system windows, references to the sleep button apply to the fn+f3
hotkey.
